Environment Modules
The PMACS cluster utilizes modules to enable users to alter their environment. These modules alter your execution path ($PATH
) and add or modify the user's environment variables. User loadable modules are available if the system default packages don't meet your requirements. Environment modules are used in place of hard-coding paths in your $HOME/.bashrc file.
To know what modules are available, you'll need to run the "module avail" command from an interactive session:
[asrini@consign ~]$ bsub -Is bash Job <9990024> is submitted to default queue <interactive>. <<Waiting for dispatch ...>> <<Starting on node063.hpc.local>> [asrini@node063 ~]$ module avail ------------------------------------------------------------------- /usr/share/Modules/modulefiles ------------------------------------------------------------------- NAMD-2.9-Linux-x86_64-multicore dot module-info picard-1.96 rum-2.0.5_05 STAR-2.3.0e java-sdk-1.6.0 modules pkg-config-path samtools-0.1.19 STAR-hg19 java-sdk-1.7.0 mpich2-x86_64 python-2.7.5 use.own STAR-mm9 ld-library-path null r-libs-user bowtie2-2.1.0 manpath openmpi-1.5.4-x86_64 ruby-1.8.7-p374 devtoolset-2 module-cvs perl5lib ruby-1.9.3-p448
Example use of modules:
[asrini@node063 ~]$ python -V Python 2.6.6 [asrini@node063 ~]$ which python /usr/bin/python [asrini@node063 ~]$ module load python-2.7.5 [asrini@node063 ~]$ python -V Python 2.7.5 [asrini@node063 ~]$ which python /opt/software/python/python-2.7.5/bin/python
After running the above commands, you will be able to use python v2.7.5 till you exit out of the interactive session or till you unload the module:
[asrini@node063 ~]$ module unload python-2.7.5 [asrini@node063 ~]$ which python /usr/bin/python
Modules may also be included in your job scripts and submitted as a batch job.
