Compilers on Commodity Clusters

See this article in context within the following user guides: Lens | Rhea

Commodity Clusters at the OLCF can be accessed via the following wrapper programs:

  • mpicc to invoke the C compiler
  • mpiCC, mpicxx, or mpic++ to invoke the C++ compiler
  • mpif77 or mpif90 to invoke appropriate versions of the Fortran compiler

These wrapper programs are cognizant of your currently loaded modules, and will ensure that your code links against our OpenMPI installation. More information about using OpenMPI at our center can be found in our Software Documentation.
