[mvapich-discuss] rewind stdin

[Sayantan Sur]

Hi Scott,

I tried the attached a serial and an MPI version of a simple program
that attempts rewind on stdin. I find that with MVAPICH-1.1 the MPI
version behaves identical to the serial one. Of course, stdin is
available only at rank 0 (MPI specification allows for this
restriction). Did you try this with mpirun_rsh?
