1) Try loading gcc and intel compilers at the same time. What happens?
$ module list
Currently Loaded Modules:
1) intel/16.0.1 2) cray_mpich/7.3.0 3) TACC/1.0
$ module load gcc
Lmod is automatically replacing "intel/16.0.1" with "gcc/5.2.0".
Due to MODULEPATH changes, the following have been reloaded:
1) cray_mpich/7.3.0
$ module list
Currently Loaded Modules:
1) TACC/1.0 2) gcc/5.2.0 3) cray_mpich/7.3.0
Having both intel and gcc compilers loaded would be a conflict, so the module system does not allow it.
2) Determine recommended compiler / dependencies for a software package you use. Are they available on Lonestar5?
*As an example application, we will consider Tophat. Listed on the Tophat website are the following dependencies: bowtie, boost
$ module avail bowtie
$ module avail boost
