tack is ³not based on any direct OFED

Doesn¹t Redhat just ship an old OFED build, or they do their own changes

of MPI's and compilers is already quite a task; making one
MPI build for this app and another MPI build for that app is sort of, not
really practical, nor is educating users to set ulimits and mca parameters per

start (we set the ulimits
in Torque).
Is it known (I know every application is different ) how much costs,
performance-wise, to have MXM with good ulimits vs unlimited ulimits, vs
not using MXM at all?

experience running recent OpenMPI with MXM enabled, and what kind of
ulimits do you have? Any suggestions/comments appreciated, thanks!
