[mvapich-discuss] Problems with mvapich2-1.7 while running osu_benchmarks

[Venkateswara Rao Dokku]

Hi,
    We are trying to run osu_benchmark tests on our customized OFED, we ran
the following tests with the open-mpi
1. osu_acc_latency
2. osu_alltoall
3. osu_bcast
4.osu_bibw
5.osu_bw
6.osu_get_latency
7.osu_latency
8.osu_mbw_mr
9.osu_multi_lat
10.osu_put_latency

they went fine.. when we tried to run the remaining tests viz.
osu_get_bw,osu_latency_mt,osu_put_bibw,osu_bibw we found some issues with
openmpi and it seems that those tests we have to run only with mvapich2. so
we shifted to mvapich2-1.7, and we try to run those tests we are getting
issues. the command used and the error is given below..


command::

mpirun_rsh -ssh -np 2 -hostfile /root/hostfile_test
/root/mvapich2-1.7/osu_benchmarks/osu_get_bw

error::
connect [mt_checkin]: Connection refused
[localhost.localdomain:mpirun_rsh][child_handler] Error in init phase,
aborting! (1/2 mpispawn connections)

the host file contains the  ip-addresses of the two nodes we want the test
to run on statrting with the local ip address..

can you help why we are getting this error i.e the root cause for this
one,..

Thanks for replying..
