[molpro-user] running parallel GA Molpro from under Torque?

Firstly, I can only echo Jeff's comments about MVAPICH2 over OpenMPI for 
the case of using Infiniband.

Secondly, you need to decide which MPI library you really want to use. 
You have given both a '-mppbase' option, and a '-auto-ga-openmpi' 
option, but these are mutually exclusive. The auto option will build 
everything, including a copy of OpenMPI, however it's use is best 
restricted to a single machine. If you want a GA/openmpi build for your 
cluster I strongly recommend to build GA against your system MPI 
library, and then pass the GA build directory via -mppbase to Molpro. 
So, removing the options which are default anyway, your configure would 
look like:

./configure -mpp -mppbase /path/to/GA/build/dir -icc -ifort -slater -noboost

and of course PATH should contain the MPI executables.

Best wishes,
