I tried OFED RC5 with Intel MPI on x86_64 and ia64 and everything seems to
be working
fine on the Mellanox card. I also put together some ofed rc5 backport
patches and RPMs for 2.6.9-34EL and am hoping to get some folks here to load
it up on a larger cluster, my
initial testing was only on small clusters, but it looks stable. 

The only problem I saw is that there is still an issue with running Intel
MPI/uDAPL
over the Pathscale (Qlogic) card. It appears to be a uDAPL or MPI problem
rather than
a problem with the Pathscale driver. I am now able to run ibv_rc_pingpong 
over the pathscale PCI-E card reliably on a 2 node cluster. We plan to
investigate
the MPI/uDAPL issue today.
