Compilers

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: GNU Collection Compiler (GCC), the Intel compiler, The Portland Group (PGI), and the Numerical Algorithms Group (NAG).

📝 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:

The Intel Compiler Suite

If you are working with another module, first you need to unload it.

You can see what the module provides with the commands module list and module display.

The Portland Group Compiler Suite

If you are working with another module, first you need to unload it.

You can see what does the module provides with the commands module list and module display.

The Numerical Algorithm Group Compiler Suite

If you are working with another module, first you need to unload it.
