[mvapich-discuss] Problem with slow start in mpirun_rsh using mvapich1.1

[Terrence.LIAO at total.com]

Dear mvapich,

I have this slow start problem and do not know how to fix it.  I am trying 
to run a very simple hello world and using this typical command:
mpirun_rsh -hostfile host.list -np 27 ./mpi_hello.exe on our IB cluster, 
from time to time it will run but in most case it give me "Timeout during 
client startup".   Any advice to fix this problem.  Is VIA_CM_TIMEOUT a 
parameter I should tune for this?

Thank you very much.
