[Beowulf] mpitest between qlocgic and mellanox/infiniband

[Jon Tegner]

Hi,

when evaluating infiniband I usually try to run "osu_latency", "osu_bw" 
and the likes (from package mpitests-openmpi). However, I have not 
managed to run these between nodes where one has a Qlogic card and the 
other one from Mellanox.

Is it a bad idea to try to use cards from different vendors in an "mpi 
environment", or am I missing something in the configuration?

Thanks,
