[mvapich-discuss] Anyone successfully running Abaqus with MVAPICH2?

[Mehmet Belgin]

Hi everyone,

We recently upgraded the hwloc library used by the schedulers (along 
with mvapich2 and all applications compiled with it), but apparently 
Abaqus is using an internal MPI (PMPI) which still points to old hwloc 
versions that are not compatible. As a result, Abaqus either crashes or 
runs extremely slow.

Abaqus documentation suggests that it may be possible to run it using an 
external MPI stack, and I am hoping to make it work with our stock 
mvapich2/2.1 that knows how to talk with the scheduler's hwloc. 
Unfortunately, however, all of my attempts failed miserably so far (no 
specific instructions for mvapich2).

I was wondering if anyone had success with getting Abaqus running with 
mvapich2. Even the information of whether it is possible or not will 
help us a great deal.

Thanks for your help!

-Mehmet
