The HPC supports four programming environment (PE) modules to easily switch between compilers. Each programming environment contains the full set of compatible compilers and libraries.
These compilers are: , the , , and the .
📝 Note: You cannot use more than one PE-module at the same time. For example, if you are working with GNU and then you decide to work with the Intel compiler, first unload the PE-gnu module and then load PE-intel.
The GNU Compiler Suite
To load the GNU module:
module load PE-gnu
You can check which modules are loaded in your system by typing:
$ module list
Currently Loaded Modulefiles:
1) gcc/5.3.0 2) openmpi/1.10.3 3) xalt/0.7.5 4) PE-gnu/1.0
To display information about the module, such as the size, the compiler, or the source from which the module was created, etc., use the following command:
$ module display PE-gnu
-------------------------------------------------------------------
/software/dev_tools/swtree/cs400/modulefiles/PE-gnu/1.0:
module-whatis PE-gnu defines the environment needed to build
applications using GNU compiler suites on this system.
conflict PE-gnu PE-intel PE-pgi
setenv PE_NAME GNU
setenv PE_CC mpicc
setenv PE_CXX mpic++
setenv PE_FORTRAN mpif90
prepend-path PATH /software/dev_tools/swtree/cs400_centos7.2_pe2016-08/PE/1.0/noarch/bin
module load xalt
-------------------------------------------------------------------
You can switch between the two versions of PE-gnu v1.0 and PE-gnu v2.0:
$ module switch PE-gnu/1.0 PE-gnu/2.0
$ module list
Currently Loaded Modulefiles:
1) gcc/5.3.0 2) openmpi/2.1.1 3) PE-gnu/2.0 4) xalt/0.7.5
The Intel Compiler Suite
If you are working with another module, first you need to unload it.
module load PE-intel
You can see what the module provides with the commands module list and module display.
$ module list
Currently Loaded Modulefiles:
1) intel/16.0.1 2) openmpi/1.10.3 3) xalt/0.7.5 4) PE-intel/1.0
module display PE-intel
-------------------------------------------------------------------

setenv PE_FORTRAN mpif90

module load xalt
-------------------------------------------------------------------
The Portland Group Compiler Suite
If you are working with another module, first you need to unload it.
module load PE-pgi
You can see what does the module provides with the commands module list and module display.
$ module list
Currently Loaded Modulefiles:

The Numerical Algorithm Group Compiler Suite
If you are working with another module, first you need to unload it.
module load PE-nag
You can see what the module provides with the commands module list and module display.
$ module list
Currently Loaded Modulefiles:
1) nag/6.0 2) mpich/3.2 3) xalt/0.7.5 4) PE-nag/1.0
$ module display PE-nag
