[openib-general] Segmentation fault on ib_read_bw

[Adit Ranadive]

I managed to get the test working .. I just restarted the server and
it was working..
Im actually doing some work with the Xen VMM and Infiniband..
I have setup 2 servers (Pentium D - x86_64 arch) with red hat
enterprise linux 4 and Xen 3 VMM running .. The IB driver seems to be
working on dom0 in any case and I can do all of the perf tests.
I wanted to know if there was any correlation between the QoS setup
done using openSM and the perf tests i.e. if I configure QoS in
opensm.opts should I be seeing marked differences in the BW from the
perf tests?
Is there any kind of documentation that gives an idea how the BW can
change for diff QoS params?

Regards,
Adit
