Softenv

SoftEnv is a utility that is supposed to help users manage complex user environments with potentially conflicting application versions and libraries.

System Default Path

When a user logs in, the system /etc/profile or /etc/csh.cshrc (depending on login shell, and mirrored from csm:/cfmroot/etc/profile) calls /usr/local/packages/softenv-1.6.2/bin/use.softenv.sh to set up the default path via the SoftEnv database.

SoftEnv looks for a user's ~/.soft file and updates the variables and paths accordingly.

Viewing Available Packages

Using the softenv command, a user may view the list of available packages. Currently, it can not be ensured that the packages shown are actually available or working on the particular machine. Every attempt is made to present an identical environment on all of the LONI clusters, but sometimes this is not the case.

Example,

$ softenv
These are the macros available:
*   @default
These are the keywords explicitly available:
+amber-8                       Applications: 'Amber', version: 8 Amber is a
+apache-ant-1.6.5              Ant, Java based XML make system version: 1.6.
+charm-5.9                     Applications: 'Charm++', version: 5.9 Charm++
+default                       this is the default environment...nukes /etc/

+gaussian-03                   Applications: 'Gaussian', version: 03 Gaussia

Listing of Available Packages

See Packages Available via SoftEnv on LSU HPC and LONI.

For a more accurate, up to date list, use the softenv command.

Caveats

Currently there are some caveats to using this tool.

  1. packages might be out of sync between what is listed and what is actually available
  2. resoft and soft utilities are not; to update the environment for now, log out and login after modifying the ~/.soft file.
Availability

softenv is available on all LSU HPC and LONI clusters to all users in both interactive login sessions (i.e., just logging into the machine) and the batch environment created by the PBS job scheduler on Linux clusters and by loadleveler on AIX clusters..

Packages Availability

This information can be viewed using the softenv command:

% softenv
Managing Environment with SoftEnv

The file ~/.soft in the user's home directory is where the different packages are managed. Add the +keyword into your .soft file. For instance, ff one wants to add the Amber Molecular Dynamics package into their environment, the end of the .soft file should look like this:

+amber-8

@default

To update the environment after modifying this file, one simply uses the resoft command:

% resoft

Usage

  • Compile programs with debugging enabled and optimizations turned off: -O0 -g
  • Request an interactive session, for example:
  • $ qsub -I -X -V -l walltime=4:00:00,nodes=2:ppn=8 -A allocation -q checkpt
    
  • Run a serial application with totalview
  • Run an MPI application by adding the switch -tv to the command line. For example:
  • $ mpirun_rsh -tv -np  -hostfile  
    

Here is a list of some commonly used command line options:

-a
Pass all subsequent arguments (specified by ) to your program. This option must be the last one on the command line.
-dbfork
(Default) Catches the fork(), vfork(), and execve() system calls if your executable is linked with the dbfork library.
-e
Tells TotalView to immediately execute the CLI commands named within this argument. All information you enter here is sent directly to the CLI's Tcl interpreter. More than one -e option is allowed per line. For example, the following writes a string to stdout:
cli -e 'puts hello'
-patch_area_base address
Allocates the patch space dynamically at the given address. See "Allocating Patch Space for Compiled Expressions " in Chapter 14 of the TotalView Users Guide.
-patch_area_length length
Sets the length of the dynamically allocated patch space to the specified length. See "Allocating Patch Space for Compiled Expressions" in the TotalView Users Guide.
-pid
Tells TotalView to attach to process after it starts executing.
-remote
Debugs an executable that is not running on the same machine as TotalView. For more information on the autolaunch feature, see "Setting Single Process Server Launch" in the TotalView Users Guide.
-r
Same as -remote.
-s
Specifies the path name of a startup file that will be loaded and executed.
