[mvapich-discuss] mpirun_rsh -v does not show version information for mvapich2

[Manhui Wang]

Hi,

It does not give version information as expected with command
"mpirun_rsh -v" for mvapich2(1.5.1p1):

mpirun_rsh -v
Unknown option
usage: mpirun_rsh [-v] [-sg group] [-rsh|-ssh] [-paramfile=pfile]
[-debug] -[tv] [-xterm] [-show] [-legacy] -np N(-hostfile hfile | h1 h2
... hN) a.out args | -config configfile (-hostfile hfile |h1 h2 ... hN)]
Where:
        sg         => execute the processes as different group ID
...


while for mvapich(mvapich-1.2rc1) it shows the version information:
mpirun_rsh -v
OSU MVAPICH VERSION 1.2-SingleRail
Build-ID: custom


It would be helpful if -v option can give useful information like
version for mvapich2.

Thank you
Manhui
