Hi Juha,
I do this for a particular MPI version we use here. Within a hierarchical
module naming scheme (HMNS), it's a little extra work because you have to
create EasyBuild compatible modules and also "pseudo" easyconfigs so that EB
can figure out where things go in the hierarchy.
As an example, here what I added to the existing MPI module to make it
EB-compatible:
# Fool EasyBuild that this is an EB module
setenv EBROOTMPICH2 ${mpi_home}
setenv EBVERSIONMPICH2 Parastation-5.0.27
conflict MPICH2
# Need to add to the hierarchy when loading the MPI version
module use
/usr/local/eb/hierarchical/installed/modules/all/MPI/GCC/4.9.1/MPICH2/Parastation-5.0.27
and here's the corresponding pseudo-easyconfig:
# This file is a dummy as I'm using the system installed MPICH2
name = 'MPICH2'
version = "Parastation-5.0.27"
homepage = 'http://www.par-tec.com/products/parastation-mpi.html'
description = """ParaStation MPI provides a standard interface for parallel
applications that require either MPI or MPI-2 library functionality. """
toolchain = {'name': 'GCC', 'version': '4.9.1'}
moduleclass = 'mpi'
As it stands there's no automatic method for this, you have to separate
compiler from toolchain for the HMNS to work, so you will be forced into faking
it for the compiler, MPI and math libraries separately. It takes a little
understanding but is very do-able.

I would like to use EasyBuild to install application level software stack on
two systems, one "regular" PC cluster, and one Cray XC30 system. I would like
to use the compilers, MPI libraries and math libraries that are already
installed on the machines as the toolchain. What would be the best approach to
use EasyBuild framework in this kind of situation?
Best regards,
Juha
