Hi,

My company is taking it's first foray into the world of HPC with an
expandable architecture, 16 processor (comprised of quad core
Opterons), one header node cluster using Infiniband interconnects.
OS has tentatively been selected as SUSE 64-bit Linux. The
principal purpose of the cluster is as a tool for spacecraft and
propulsion design support. The cluster will therefore be running
the most recent versions of commercially available software -
initially for FEA and CFD using COMSOL Multiphysics and associated
packages, NASTRAN, MatLab modules, as well as an internally
modified and expanded commercial code for materials properties
prediction,with emphasis on polymer modeling (Accelrys Materials
Studio). Since we will be repetitively running standard modeling
codes on this system, we are trying to make the system as user
friendly as possible... most of our scientists and engineers want
to use this as a tool, and not have to become cluster experts. The
company WILL be hiring an IT Sys Admin with good cluster experience
to support the system, however...
Question 1:
1) Does anyone here know of any issues that have arisen running the
above named commercial packages on clusters using infiniband?
Question 2:
2) As far as the MPI for the system is concerned, for the system
and application requirements described above, would OpenMPI or
MvApich be better for managing node usage?
none of them will manage the node usage - you have to assemble a node
list for every run by hand. What you might be looking for is a
resource manager like SGE, Torque, LSF, Condor,... und run parallel
jobs under their supervision.

ANY help or advice would be greatly appreciated.
Thanks in advance
