I ran the qperf command between two compute nodes ( b4 and b5 ) and got:
[hussaif1@lustwzb5 ~]$ qperf lustwzb4 -t 30 rc_lat rc_bi_bw
rc_lat:

latency = 7.73 us
rc_bi_bw:
bw = 9.06 GB/sec
If I understand correctly, I would need to enable ipoib and then rerun
test? It would then show ~40GB/sec I assume.
No. 9GB/s is about 80 Gb/s. Infiniband is working. Looks like you
might have dual-rail IB setup, or you were doing a bidirectional/full
duplex test.
