QLogic OFED+ Host Software Page 9 of 20
Known Issue
Workaround
Running MPI microbenchmarks over verbs can exhibit low
performance using the osu_bw and osu_bibw tests. It is not
known how much this affects applications performance.
Use MPIs built for use with PSM, QLogic's
high-performance interface for MPI on
QLogic Host Channel Adapters. These
MPIs are the MPIs that are listed in the
mpi-selector --list with "_qlc" as
part of the name, or QLogic MPI.
The ib_send_bw microbenchmark that comes with OFED
1.5.2, and with this host software release, had a
regression. Consequently, the command hangs when it is
run without the -a (all sizes) option. This benchmark is part
of the perftest-1.3.0-0.28 suite of benchmarks provided
with OFED 1.5.2.
Use the -a option.
