Bash

The RedHat7 machines do not have the /usr/local/etc/bash_profile file. To avoid an error message appearing when you login to to one of the machines add the following to your ~/.bashrc

 #source bash_profile on debian machines
 [ ! -f /etc/redhat-release ] && source /usr/local/etc/bash_profile

Be sure to remove other calls to source /usr/local/etc/bash_profile from your ~/.bashrc.

Modules

Modules are install for GCC, MPICH, and several commonly used software packages.

Setup

Setup your environment to access the modules by running the following command:

 #setup lmod
 export PATH=/usr/share/lmod/lmod/libexec:$PATH
 #setup spack modules
 unset MODULEPATH
 module use /opt/scorec/spack/lmod/linux-rhel7-x86_64/Core/
 module use /opt/scorec/modules
