[mvapich-discuss] error closing socket at end of mpirun_rsh original posted Oct 11

[Dhabaleswar Panda]

Hi Scott,

As we discussed off-line, you have access to a solution to this problem.
Let us know how it works.  This solution is also being available with the
enhanced and strengthened mpirun_rsh of mvapich 1.0 version.

Thanks,

DK
