Greetings and best wishes for 2014:

Our cluster has two working builds of 2012.1pl9 

(a) MPI-2 with Intel MPI, which I configured as follows (the "module" stuff sets up relevant compilers and libraries):

./configure -batch -ifort -icc -blaspath /usr/local/intel/Compiler/2013.5.192/composer_xe_2013.5.192/mkl/lib/intel64  -mpp -openmp -mppbase /usr/local/intel/impi/ -prefix /home/co

This seems to work OK, except that I obviously have only N-1 processes doing any actual computing. (Is having a dedicated "helper process" beneficial for very large jobs?)

(b) GA-MPICH using

./configure -batch -blaspath /usr/local/intel/Compiler/2013.5.192/composer_xe_2013.5.192/mkl/lib/intel64 -icc -ifort -mpp -openmp -auto-ga-mpich -prefix /home/comartin/apps/molpro2012.1pl9MPICH 

For various reasons our sysadmin recommends that we use Intel MPI exclusively. How would I go about compiling a GA-IMPI version? Any suggestions on how to hack in a -auto-ga-impi stanza in configure?

Many thanks in advance
Jan Martin

PS: we basically do NOT run across nodes.
