The LONI computing facilities, encompassing its hardware, software, network connections, and data, are a vital but limited resource for the Louisiana community. Therefore the LONI sites have an obligation to protect their facilities and ensure they are used properly. Allocations are used to assure equitable consumption of system resources, while personal access to the systems is controlled via user accounts. You, personally, are constrained by legal and other obligations to protect resources and the intellectual property of others on the systems.
Given the extensive nature of these resources, responsibilities are attached to the right of access. Responsible user conduct is required so as to assure fair access by all researchers. Failure to use these resources properly may result in various penalties, including, but not limited to, loss of access, academic, civil and/or criminal action.
2.1. Individual Account Management
You have the responsibility to protect your account from unauthorized access, and for the proper expenditure of allocated resources. Tools are provided to help you manage your resources, but you are responsible for using these tools properly.
2.1.1. Valid Contact Email
Every account has a contact email address associated with it, and this address must be issued by a LONI institution. Email is used as the primary communication channel between LSU@HPC and the user. The user is responsible for keeping this address up to date. In the event that an address is discovered to be invalid or unresponsive, the associated user account will be locked until the issue is resolved.
2.1.2. No Account Sharing
Your account is for your personal use only. It is not to be shared with others; neither students nor other collaborators. Others who need system access must request their own account. User authentication certificates, if they are used, are considered personal accounts and are not to be shared. Any activity indicating account sharing will result in the account being locked until remedial action is taken. Repeated misuse may result in permanent loss of system access.
2.1.3. Protecting Passwords
Your passwords and certificates are the keys to account access. You are responsible for their protection and proper use. Protective behavior includes:
- never sharing passwords
- never writing passwords down where they can be easily found
- never using tools which expose passwords on the network (e.g. telnet).
See Guidelines, Section 5, for more information.
The private key portion of an authentication certificate is the equivalent of a password. If you use certificates, you are responsible for ensuring that file and directory permissions prevent others from reading or copying any private keys.Back to Top
2.2. Fair Use
Access to a system does not grant you blanket authorization for any and all activity. You must recognize that reasonable use may vary from machine to machine within a system, depending on the function of the machine. Machines in a cluster serve one of two basic functions.
2.2.1. Computational Nodes
These are the nodes which perform the intended heavy computational work of a cluster. They are accessed via the job scheduler (e.g. LoadLevel or PBS) through the submission of job control scripts. Computational tasks are never to be run on the cluster head nodes, as this has the potential of impairing operation of the entire system.
2.2.2. Head Nodes
Head nodes are used for the interactive work required to prepare a computational task. Appropriate work on the head nodes includes: light editing, compiling, post analysis previewing, and job script creation. Extensive post processing should be done on the compute nodes. Any processing on the head nodes which adversely impacts system operation is subject to preemptory termination. Repeated abuse may result in the locking of user accounts or other administrative action as deemed appropriate.
2.2.3. Authorized Use
Authorized use of the system is defined by the purpose outlined in the proposal on which the usage allocation is based. Your use of the account is limited to activities reasonably required to accomplish that purpose.
2.2.4. Unacceptable Behaviors
The following activities are explicitly considered unacceptable and are subject to the penalties outlined below:
- using, or attempting to use, LONI computing resources without a valid allocation, or for purposes other than those stated in the allocation proposal.
- tampering with or obstructing the operation of the facilities.
- reading, changing, distributing, or copying others' data or software without authorization.
- using LONI resources to attempt to gain unauthorized access to other (non-LONI) sites.
- activities in violation of local or federal law
2.3. Reporting Suspicious Activity
You are responsible for reporting, as soon as possible, any suspicious activity you notice on your account, and exposure or compromise of passwords, passphrases, or certificates. See Section 5 for reporting procedures.Back to Top
2.4. Data Confidentiality
You are responsible to ensure the confidentiality of any data you use on LONI resources that is restricted from general public access. LONI sites provide technology to preserve the confidentiality of data, but it is your responsibility to use that technology appropriately. Such data may include:
- Intellectual property, such as report drafts or research in progress,
- Proprietary data, such as data owned by a specific company, or licensed applications.
- Regulated data, such as medical, personal identifying information, or student records.
It is your responsibility to be aware of any requirements on a data set and verify that a given LONI site can provide appropriate protection before attempting to use it. Be aware that some sites may be subject to state laws which impose requirements on data stored on those sites.Back to Top
Papers, publications, and web pages of any material, whether copyrighted or not, based on or developed under LONI-supported projects must acknowledge this support by including the following statement:
- This material is based upon work supported by the Louisiana Optical Network Institute (LONI).
2.6. Software Development
Software developed with allocations approved by LONI or by proxy, via the allocations processes governing allocation of LONI resources, is subject to intellectual property rights as established by the LSU and participating institutions. Questions should be directed to the Director, Office of Intellectual Property, LSU, or the user’s home institutution.1Back to Top
Work performed under a peer-reviewed allocation must be published in the open literature.Back to Top
2.8. Non-Academic User Requirements
Non-academic (corporate/industrial, government, etc.) users frequently have more stringent usage requirements than those that might be provided by the LONI as a whole or by a particular site within LONI. It is the user's responsibility to assure the resources used satisfy the requirements of their organization. For LSU users, see: Office of Intellectual Property site.Back to Top
2.9. Software Licenses
All software used on LONI systems must be appropriately acquired and used according to the specified licensing. Possession or use of illegally copied software is prohibited. Likewise users shall not copy copyrighted software or materials, except as permitted by the owner or the copyright. Some installed software may require special authorization in order to be used. Users must abide by the licensing requirements and protect it from misuse.Back to Top
2.10. Final Reports
Requests for subsequent allocation awards will not be allowed until an end of project report has been received for all prior awards. Copies of prior final reports must be attachmented to the submitted proposal.Back to Top
2.11. Additional Requirements
Individual sites may be subject to organizational policies with additional requirements beyond this policy. Those organizations will make those policies available. It is your responsibility to be aware of and abide by those policies.Back to Top
Failure to abide by these policies may result in a variety of penalties imposed.
3.1. Account Suspension/Revocation
Accounts may be temporarily suspended or permanently revoked if compromised or abused. Your account may be suspended without advance notice if there is suspicion of account compromise, system compromise, or malicious or illegal activity.Back to Top
3.2. Loss of Allocation
Unauthorized behavior can result in loss of your current allocation, and may lead to the inability to obtain future allocations.Back to Top
3.3. Administrative Action
Unauthorized activity may be reported to your PI, your advisor, or your home institution for administrative review and action.Back to Top
3.4. Civil Penalties
Civil remedies may be pursued to recoup costs incurred from unauthorized use of resources or incident response due to compromise or malicious activity.Back to Top
3.5. Criminal Penalties
Activities in violation of federal, state, or local law may be reported to the appropriate authorities for investigation and prosecution.Back to Top
4.1. Additional requirements
As stated in Section 2.5, individual LONI sites may be subject to requirements beyond the scope of this document. However, it is your responsibility to identify if such requirements exist.Back to Top
4.2. Support/Diagnostic Access
LONI site personnel may review files for the purposes of aiding an individual or providing diagnostic investigation for LONI systems. User activity may be monitored as allowed under policy and law for the protection of data and resources. Any or all files on LONI systems may be intercepted, monitored, recorded, copied, audited, inspected, and disclosed to authorized site or law enforcement personnel, as well as authorized officials of other agencies, both foreign and domestic. By using LONI systems, users acknowledge and consent to this activity at the discretion of authorized site personnel.Back to Top
4.3. Access Notification
Access to user data and communications will not normally be performed without explicit authorization and/or advance notice unless exigent circumstances exist. Post-incident notification will be provided in such cases.Back to Top
The following are suggestions for helping maintain the security of your account.Back to Top
5.1. Password Management
- Do not write down your password where it can be easily found and/or associated with your account.
- Do not tell anyone your password, not even LONI support staff. Support staff will never need your password, will never ask for it, and will never send a password in e-mail, set them to a requested string, or perform any other activity which could reveal a password.
- If someone insists they need your password to do something, report it to the LONI helpdesk: firstname.lastname@example.org.
- Do not store your password(s) in unencrypted files or even in encrypted files if possible.
- Pick passwords that are difficult to guess. Birthdays, family names, and single dictionary words are examples of easily guessed passwords.
- Change your password periodically, even if you have no reason to believe that anyone else has it.
5.2. Reporting Suspicious Activity
5.2.1. Password Exposure
If you think your password may have been compromised or exposed, but have no reason to believe that your account has been used, change your password immediately.
5.2.2. Certificate Exposure
If you believe your certificate has been exposed, revoke your certificate and have a new one issued.
5.2.3. Account Compromise or Suspicious Activity
If you believe your account has been compromised or find signs of suspicious activity, take the following actions:
- notify the LONI helpdesk immediately (email@example.com)
- do not modify files found in your account
- do not execute unknown programs you might find
- if possible, do not use your account until the issue is resolved
Some indications of account compromise include:
- files in your home directory or project areas which you did not create
- alteration or deletion of your files not done by you
- discrepancies between your allocation balance and what you think you have used
The central point of contact for any problems and concerns with regards to this policy is the LONI help desk which can be reach at firstname.lastname@example.org. Other modes of contact are listed on the LONI web site help page.Back to Top
LONI User Allocation and Account Policy
Last revised: 21 Aug 2013.
▶ Table of Contents
- Accounts and Allocations
- The Allocation Process
- Machine Access Policy
- Resource Allocation Committee Members
1. Accounts and Allocations
LONI (Louisiana Optical Network Initiative) maintains several high performance computing (HPC) systems at its member sites, interconnected by a high speed optical network. The machines currently include IBM Power5-575 systems and Intel Xeon-based clusters. Detailed information can be found on the LONI web site. LONI controls access to these resources via a formal user allocation and account creation process. All decisions in these matters are made by committee made up of representives from each of the LONI member organizations.
Gaining access to LONI resources, be it CPU time or data storage, involves a two step process. The first step requires the submission of a proposal outlining the resource requirements. Approval of the request results in the award of an allocation. Allocations are awarded on a by-project basis to the principle investigator (PI) who submitted the proposal. Full-time faculty and research staff at LONI Member and Associate institutions are eligible to serve as a PI. The LONI Management Council reserves the right to designate others for PI eligibility. Allocations for CPU time are blocks of Service Units (SU) awarded for use on a specific machine, while storage allocations are awarded in terms of Gigabytes (1 billion bytes) of disk space. Currently, only extended storage on the /project file space requires an allocation.
The second step involves the authorization of system user accounts for the expenditure of allocated resources. In order to run a program, a user must be able to charge expenditure to an allocation. To accomplish this, tools are made available to the PI to control authorization of users. The PI associates an email address with an allocation to which all user account requests are sent for authorization. The PI is responsible for all authorizations, but may formally delegate someone to manage this process. Once a user account is authorized to use an allocation, the user is allowed to submit jobs or otherwise expend the allocation. This implies that a user must be authorized for at least one non-expired allocation before the systems can be used. Likewise, a user account may be authorized to use multiple allocations. It becomes the responsibility of the PI and user to make sure the appropriate allocation is charged for work.
Currently, one SU corresponds to one hour of wall-clock time on one processing core. A single machine will have multiple nodes (individual servers) available, and multiple cores within each node. This allows many cores to be used for a single parallel processing job, but can lead to not-so-obvious charges. For example, running for 1 hour using 8 cores on an 8-core node consumes 8 SU's. On the other hand, running for 1 hour on 1 core of the same 8 core node, which allows the single core to access all of the node memory, also consumes 8 SU's. In simple terms, the number of cores that are reserved for a job, and hence are unavailable to others, is the number used to calculate SU usage.Back to Top
2. The Allocation Process
LONI resources are partitioned by category, and all allocation proposals go through the LONI Resource Allocation Committee (LRAC). The LRAC represents three distinct approval authorities: individual member institutions; the LONI Management Council (LMC), represented by the LONI director; and the LRAC as a panel. Table 1 shows the distribution of LONI resources by category:
|Category||Available Resources||Allocation Authority|
|Louisiana Non-Member LONI||5%||LRAC|
|Small Allocation (< 50,000 SU’s)||30%||By member, 5% per institution.|
|Large Allocation (> 50,000 SU’s)||45%||LRAC|
Allocations are granted at the beginning of every calendar quarter and have a duration of one year. Application deadlines are one month prior to the start date, as summarized in Table 2.
|January 1||December 1 (prior year)|
|April 1||March 1|
|July 1||June 1|
|October 1||September 1|
A PI may request, or be requested, to make a formal presentation to the allocation authority in conjunction with their proposal submission. At the end of any allocation, a summary report must be submitted to the authorization authority. Any request for allocation renewal must include a summary report, including renewals for startup allocations. The summary should indicate if the goals of the proposed work were accomplished, any major results, and a list of any publications that result.
To facilitate management of proposals, they are identified as belonging to one of several classes (Table 3).
|Economic||A proposal to assist commercial interests with the adoption of high performance computing as part of their business process. Awarded by the LMC from the Economic Development resources.|
|Discretionary||A proposal determined to be of value, but lying outside the normal allocation process. Awarded by the LMC from the Discretionary resources.|
|Small||A proposal requesting a Small allocation. May be awarded from LRAC or institution resources.|
|Startup||A proposal requesting an allocation for the purpose of exploring the value of high performance computing for a new project. This may be awarded in any category, within a member's 5% resource pool. Only 2 startup allocations may be active at any time per PI. Serial application for Startup Allocations is discouraged as the intent is to use them to develop proposal material for one of the other allocation types.|
|Large||A proposal requesting a Large allocation. May be awarded by the LRAC against Large or Non-Member resources. Large requests are limited to 4M SU, and a PI may have a total of 6M SU active at any given time. Only faculty members of LONI member and Louisiana associate institutions may serve as the PI for large allocations.|
2.1 Proposal Requirements
A request for an allocation requires that a formal proposal be submitted via the LONI web interface to the LRAC. The proposal is expected to be 5 pages or less, and concentrate on justifying the computational resources requested. The following outline should be followed:
- Problem Statement - section limited to 1 page, or less, describing the desired outcomes of the project.
- Background - section limited to 1 page or less, describing how the resources will be used to address the problem (i.e. student access for course work, specific models, etc.).
- Methodology - section limited to 1 page, or less, describing the computational methodology that will be used. This should include the applications required.
- Research Plan - section limited to 1 page, or less, describing the research schedule, including the anticipated expenditure of granted resources. Allocations are assumed to be uniformly consumed over their lifetime. If this will not be the case, an estimate of expenditure by calendar quarter is required.
- Requirements Analysis - section limited to 2 pages, or less, detailing the basis for the requested computer time. Requests for large allocations must exhibit an understanding of application efficiency, scaling, and provide accurate estimations of the SU requirements.
- Attachments - must include summary reports from previous allocations.
Please note that the maximum proposal page limit is 5, not including summary reports in the Attachments. The page limit was chosen with an eye to making it relatively easy to compose an allocation request, or to modify and reuse a successful application made to another center. Additional information may be attached as addendums, such as copies of awarded grants which will be supported by the requested resources.
Project allocations are competitively reviewed and granted based upon the description of the proposed research and the use of technology. For Large Allocations, priority is given to funded research. All decisions made by the LRAC are deemed final. Appeals can be directed to the LMC or the member institution council representative.
Renewal allocations follow the same process as all other allocations. Proposal writers should be aware that both past usage history and submission of progress reports will be considered in the award determination. Applications for allocation renewals should ideally cite peer reviewed publications that acknowledge LONI resources and only require an updated version of a previously successful application.Back to Top
2.2 Allocation Management
An allocation is considered valid so long as a positive resource balance remains, and the expiration date has not been exceeded. Once an allocation expires, or has been fully consumed, users accounts will be blocked from submitting work against the allocation. There is no mechanism for extending an allocation beyond one year, nor for adding resources once an allocation has been expended.
User accounts must be associated with a valid allocation, and if not, will be retained for a maximum of 1 year pending authorization against a renewed or different allocation. With these restrictions in mind, the PI is required to use the tools provided to monitor system usage and control authorization of project member accounts. PI's are strongly advised to carefully budget their usage appropriately throughout the year. Automatic reminder emails will be sent by the management system as an allocation nears expiration. PI’s are ultimately responsible for assuring that a current and actively monitored management email address has been assigned to each allocation.
At the end of any allocation, a short summary report must be submitted to the allocation committee. Failure to submit this report may be used in the consideration of future allocations. The report may simply reference any formal publications that resulted from using LONI resources, or provide a highlevel overview of what was accomplished.Back to Top
2.3 Early Allocation Access
If a PI who has already been awarded a large allocation by LRAC puts in a new request, and there is a good reason to start the project before the next cycle, then the local representative can tell staff to award as much as 25% of the project request. Justification must be provided in the renewal proposal. The LRAC committee would be made aware of this action and its reasons by the local representative using "LONI Allocations" listerver.Back to Top
3. Machine Access Policy
3.1 Job Queueing
Various workload balancing algorithms are used to determine how jobs are assigned resources on a given machine. The way a job is handled is determined by the job queue it is submitted to. Efficient use of the queing system requires that users request runtimes consistent with estimated runtimes of their jobs. In particular, requesting more time than is necessary for a particular job can lead to inefficient and unfair queuing. Therefore, users that routinely request more time than is needed for their jobs are subject to a “priority penalty” that will lower the priority of their jobs. Each system sets a maximum number of jobs that a single user may have running without special permission (see below). There is no limit to the number of jobs that are particular use may have queued. Users that wish to obtain a higher priority for their jobs may use special priority queues (see below).Back to Top
The available processors are currently divided into 2 architecture specific groups: IBM P5-575 systems running AIX, and Intel x86 sustems running Linux. The processors in each group are further subdivided into preemptory and dedicated pools. Certain mission critical applications, such as storm surge prediction during a hurricane threat, are granted immediate access to processors in the preemptory pool. Processors in the dedicated pool are used to run all other job types. The processors are accessed through different job queues.
There are 5 job queues which use different combinations of the processor pools, and allow for different job characteristics.
3.2.1. Preempt Queue
The preempt queue controls access to the preemptory pool. Authorized applications submitted to this queue will cause the termination of all other user applications running on preemptory nodes.
3.2.2. Checkpt Queue
The checkpt queue controls access to nodes in both the dedicated and preemptory pool. Jobs running in this queue may be subject to termination by the preempt queue, thus are implicitly assumed to support restarts based on periodically saved information. No refunds of lost SU's are offered if jobs in the checkpt queue are terminated by preemption. The user running jobs without restart capability assume this risk. However, the benefits from using this queue include access to larger numbers of nodes, and/or faster throughput, depending on how busy the queue is.
3.2.3. Workq Queue
The workq queue controls access to nodes in the dedicated pool. Jobs in the work queue will run until they terminate as planned, their requested run time has expired, or they stop due to an abnormal system failure. Jobs which are terminated due to system errors beyond the user's control may be subject to refund of expended SU's. Poor planning is not considered grounds for a refund.
3.2.4. Interactive Queue
The interactive queue gives real-time access to jobs for on-line analysis or debugging, but only allows very short run times. It supports development work, but not production.
3.2.5. Priority Queue
The priority queue controls nodes in the dedicated pool, but allows applications to be given higher priority with prior approval. Approval may be granted during training sessions, for demonstration purposes, or other special needs. The SUs charged will be adjusted by a factor of 1.3, and no more than 20% of an allocation may be expended in the queue. Requests for priority access should be directed to email@example.com. This queue does not impact other running user jobs, but will delay the start of lower priority jobs already in the queue.
3.2.6. Queue Availability
The named queues do not necessarily exist on all machines, and the maximum time allowed in the queues will vary from machine to machine. For system specific information, please refer to the architecture group Running Jobs pages on the LONI documentation web site.Back to Top
Currently disk space usage is controlled via user quotas rather than on a per-project basis. Storage may become an allocated resource in the future. At such time, a request for storage space will be required in the allocation request. At the current time, an estimate of required space is requested.Back to Top
3.4. Special Requests
A request for special access to LONI machines (such as usage of all nodes on a machine or exceptionally long runs) must be explicitly stated in the proposal for LONI resources. Appeals to the decision of the LRAC may be made to the LONI Management Council.Back to Top
4. Resource Allocation Committee Members
The current LRAC members shown in Table 4.
Each member holds approval authority for their respective institution. The LONI Director is also a member, and holds approval authority for the LONI Management Council.Back to Top
LONI Storage Policy
Last revised: 5 January 2011
▶ Table of Contents
1. Storage Systems
Available storage on LONI high performance computing machines is divided into six file systems (Table 1).
|Scratch||Storage on a node that is available only during job execution.|
|Work||Storage provided for the input, intermediate, and output files of a job.|
|Home||Storage provided to each active user account.|
|Project||Storage provided for a specific time to hold project-specific data.|
|PetaShare||Storage funded via NSF.|
|Archival||Long term storage (TeraGrid users only).|
All of the file systems share common characteristics. When they are too full, system performance begins to suffer. Similarly, placing too many individual files in a directory degrades performance. System management activities are aim at keeping the different file systems below 85% of capacity. It is strongly recommended that users hold file counts below 1,000, and never exceed 10,000, per directory. If atypical usage begins to impact performance, individual users may be contacted and asked to help resolve the issue. When performance or capacity issues become significant, system managers may begin purging files, stopping jobs, or take other actions to ensure continued system operation.
Management makes every effort to avoid data loss. In the event of a failure, we will make every effort to recover data. However, the volume of data housed makes it impractical to provide system-wide data backup. Users are expected to safeguard their own data by making sure that all important code, scripts, documents and data are transferred to another location in a timely manner.Back to Top
2. File System Details
Scratch space is available on all systems. You are free to use the scratch space, but files are subject to deletion once a job ends. The size of this file system will vary from system to system, and possibly across nodes within a system. This is an ideal place to put any intermediate data file that your job may need only while it is executing. Users should not have any expectation that files will exist after a job terminates.
Work is the primary storage that you will utilize when running jobs. Work is a common file system that all nodes have access to. It is ideal for input files, checkpoint files and output. Some systems may have an enforced storage quota per user, but Work space maybe exempt from this quota. However, Work is a shared resource that all jobs utilize. No single user should consume an excessive amount of space for long periods of time.
On some systems, Work has quotas enforced per user. This does not imply that each user should intend to fully consume this amount, since the quota system uses overbooking to optimize available space. This quota serves as a hard upper limit to prevent a single user from disrupting performance of the entire system. Files on Work will persist for some time after a job completes. This allows users to retrieve results and move them to a more permanent location. Users should not have any expectation of backup.
Work may be purged periodically, which means users should have no expectation that the storage will persist for long periods of time. The criterion for purging files is based on age, such as removing of any file not accessed in the last 30 days. This age limit may be shortened or combined with other criteria, such as file size, as necessary to maintain the system’s operational status.
All user home directories are located in the Home file system. Home is intended for the user to store source code, executables, and scripts. Home maybe considered “persistent” storage. The data here should remain as long as the user has a valid account on the system. Home will always have a storage quota, and is clearly a hard limit. While Home is not subject to management activities controlling capacity and performance, it should not be considered permanent storage, as system failure may result in the loss of information. Users should arrange for backing up their own data.
The Project file system may be available on some systems, and provides space specific to a project. Project space allocations must be requested, and they are available for a limited time period. Allocations are typically 6 months or less. Two months before an allocation expires, the user will be notified by email. Users may request to have the allocation extended. Renewal requests should be submitted at least 1 month prior to expiration to allow decision and planning time. If the storage allocation is not extended, the user will have 1 month after the expiration date to off-load their data. Users should have no expectation that data will persist after a project’s expiration, thus alternate safe keeping and data protection actions must be taken in advance.
2.5 Archival (TeraGrid Users Only)
Archival space is intended for long-term storage of user data. Users will be granted an amount of space for a period of time. Users can expect allocations to be for 1 or more years. Archival storage provides a single copy of data.
PetaShare is a NSF funded project lead by Dr. Tevfik Kosar. His group is responsible for all allocations, and establishes the usage policies. Please visit http://www.petashare.org/ for more information.Back to Top
3. System Specific Information
|System||File System||Storage (TB)||Quota (GB)||Purge File Limit (Million)|
|Dell x86 5TF Clusters (Eric, Oliver, Louie, Poseidon, Painter)||Work||9 (Lustre)||100||2|
|IBM P5-575 (Bluedawg, Ducky, Zeke, Neptune, Lacumba)||Work||0.27/1.8 (NFS)||20 / 40||0.5|
|Dell x86 50TF Cluster (QueenBee)||Work||60 (Lustre)||(none)||8|
|"||Project||60 (LPFS)||By request||N/A|
As discussed in the Introduction, the file systems are also subject to purge if usage exceeds 85% of capacity.Back to Top
4. Job Use
On all systems, jobs must be run from the Work file systems, and not from the Home or Project file systems. Files should be copied from Home or Project space to Work before a job is executed, and back when a job terminates, to avoid excessive I/O during execution that degrades system performance.Back to Top
5. Project Allocation Requests
Space is allocated on the Project file system by request only for periods of 6 months. A request for initial or renewal allocation may be made by sending an email to firstname.lastname@example.org. The email must include the name of the PI, a valid contact email, any existing allocation account information (CPU or storage), and a justification statement. Allocations are divided into 3 classes, each with a separate approval authority (Table 3). All storage allocation requests are limited by the available space, and justifications are required to be commensurate with the amount of space requested. All requests should be sent to email@example.com.
|Small||Up to 100GB||HPC@LSU Operations Manager|
|Medium||Between 100GB and 1TB||HPC@LSU Director|
|Large||Over 1TB||LONI Resource Allocation Committee|
Requests that must be approved by the LONI Resource Allocation Committee will be forwarded to firstname.lastname@example.org.Back to Top
Researchers are asked to acknowledge their use of LONI resources in any publications or reports that result from their research. The following statement should be included in any such work:
Portions of this research were conducted with high performance computational resources provided by the Louisiana Optical Network Initiative (http://www.loni.org).
