* I recommend to use the new ''Hydra'' MPI process manager. See sec. ''2.4 Scalable Process Management System'' in the [http://software.intel.com/sites/products/documentation/hpc/mpi/linux/reference_manual.pdf Reference Manual]. This avoids the need to set up and tear down the older and considerably less stable MPD manager.

* The '''openmpi''' and '''impi''' modules can '''coexist at runtime''' if:
** impi is loaded first and is called using <code>mpiexec.hydra</code>,
** ompi is loaded second and is called using <code>mpirun</code>,
** you don't attempt to compile software using the convenience wrappers like <code>mpicc, mpif90,</code> etc. For these wrappers, the last module loaded will be active. It may be possible to use full paths like <code>$IMPI_HOME/bin/mpif90</code>, but this has not been tested fully.

This is an overview of the compilers and MPI libraries available on Carbon. Each package name leads to its documentation.

Module catalog.

Compilers

GNU family

Intel Software Development Products

As of 2011, we have the following tools under support within the Intel® Composer XE 2011 for Linux bundle.

Documentation is installed locally mainly under: 

$ICC_HOME/Documentation

$ ls -F $ICC_HOME/Documentation/en_US

No longer maintained on Carbon:

MPI

OpenMPI

This is the primary and recommended MPI version. It supports Ethernet and InfiniBand interconnect, with InfiniBand set as default by means of an OMPI_MCA_… environment variable.

Intel MPI

MPICH/MPICH2

  • Not installed explicitly, but Intel-MPI is based on MPICH2 and provides an MPICH2 runtime environment for precompiled binaries.
