Hello,
I have MVAPICH2 1.8a1. With osu-micro-benchmarks 3.5.1, I find that the
osu bidirectional and unidirectional bandwidth tests hang. The latency
test runs fine.
$ mpirun_rsh -np 2 -host hosts osu_latency
# Size Latency (us)
0 3.87
1 3.94
2 3.95
4 3.95
8 3.95
$ mpirun_rsh -np 2 -host hosts osu_bibw
# OSU MPI Bi-Directional Bandwidth Test v3.5.1
# Size Bi-Bandwidth (MB/s)
Each node runs Linux 2.6.x (x86-64). MT25204 [InfiniHost III Lx HCA]
(rev 20) is the InfiniBand adapter. mpicc is set to use ICC 11.1. Any
help will be appreciated.
Thanks,
Uday
