Hi,
 I have managed to install MVAPICH on my system(2
opteron based systems connected by infiniband HCAs). 

1. On trying to run code using mpirun is get the
following:
> mpirun -np 2 -hostfile nodelist ./osu_bw_c
Unrecognized argument -hostfil ignored.
Cannot find MPIRUN machine file for machine ch_gen2
and architecture LINUX.
(no device specified.)

2. on trying to use mpirun_rsh 
> mpirun_rsh -np 2 -hostfile nodelist ./osu_bw_c
 there is no output.

Could you please help in this.

regards,
-Mahesh Barve
