Built and ran just like(*) 1.3.2 on my limited tests (that is, worked quite
well)
OS:CentOS-5.3.x86_64 with its own OFED
HW:ConnectX-DDR on a Nehalem dual-quad platform
Size:4 nodes
Compile

I originally posted this to the users list maybe it should have gone here. I
talked to Jeff Squyres about this bug at SC08 and he thought it would be nice
to have it fixed before 1.3.
The bug probably is in ompi/datatype/dt_copy.c:ompi_ddt_copy_content_same_ddt
unless I misunderstood Jeff :-)
Our new HP cluster has 25208 HCAs (Mellanox Arbel) but a new vendor-id... We
have 0x1708 (presumably HP, hardware wise Cisco (Mellanox)) to add to the
existing list in share/openmpi/mca-btl-openib-hca-params.ini that currently
contains:
# Mellanox 0x2c9
# Cisco 0x5ad
# Silverstor

I recently tried ompi on early ConnectX hardware/software.
The good news, it works =)
However, ompi needs a chunk of options set to recognize the
card so I made a small patch (setting it up like old Arbel
style hardware).
Patch against openmpi-1.3a1r14635
