The information here is applicable to LSU HPC and LONI systems.
A user may choose between using /bin/bash and /bin/tcsh. Details about each shell follows.
System resource file: /etc/profile
When one access the shell, the following user files are read in if they exist (in order):
- ~/.bash_profile (anything sent to STDOUT or STDERR will cause things like rsync to break)
- ~/.bashrc (interactive login only)
When a user logs out of an interactive session, the file ~/.bash_logout is executed if it exists.
The default value of the environmental variable, PATH, is set automatically using SoftEnv. See below for more information.
The file ~/.cshrc is used to customize the user's environment if his login shell is /bin/tcsh.
Modules is a utility which helps users manage the complex business of setting up their shell environment in the face of potentially conflicting application versions and libraries.
When a user logs in, the system looks for a file named .modules in their home directory. This file contains module commands to set up the initial shell environment.
Viewing Available Modules
$ module avail
displays a list of all the modules available. The list will look something like:
--- some stuff deleted --- velvet/1.2.10/INTEL-14.0.2 vmatch/2.2.2 ---------------- /usr/local/packages/Modules/modulefiles/admin ----------------- EasyBuild/1.11.1 GCC/4.9.0 INTEL-140-MPICH/3.1.1 EasyBuild/1.13.0 INTEL/14.0.2 INTEL-140-MVAPICH2/2.0 --- some stuff deleted ---
The module names take the form appname/version/compiler, providing the application name, the version, and information about how it was compiled (if needed).
Besides avail, there are other basic module commands to use for manipulating the environment. These include:
add/load mod1 mod2 ... modn . . . Add modules rm/unload mod1 mod2 ... modn . . Remove modules switch/swap mod . . . . . . . . . Switch or swap one module for another display/show . . . . . . . . . . List modules loaded in the environment avail . . . . . . . . . . . . . . List available module names whatis mod1 mod2 ... modn . . . . Describe listed modules
The -h option to module will list all available commands.
Module is currently available only on SuperMIC.
- 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
$ mpirun_rsh -tv -np
Here is a list of some commonly used command line options:
- Pass all subsequent arguments (specified by
) to your program. This option must be the last one on the command line.
- (Default) Catches the fork(), vfork(), and execve() system calls if your executable is linked with the dbfork library.
- 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.
- Tells TotalView to attach to process
after it starts executing.
- 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.
- Same as -remote.
- Specifies the path name of a startup file that will be loaded and executed.
