[mvapich-discuss] mvapich2 and mpirun_rsh

[Bryan Putnam]

Hi All,

I've built 

mvapich2-1.4rc1 with configure

$MPI_SRC/configure \
 --with-rdma=gen2 \
 --with-ib-libpath=/usr/lib64 \
 --enable-fast \
 --enable-debuginfo \
 --enable-sharedlibs=gcc \
 --enable-f77 \
 --enable-f90 \
 --enable-cxx \
 --enable-romio \
 --with-pm=mpd \
 --without-mpe \
 --prefix=$MPI_INSTALL/$CVER \
 > configure_$CVER.log 2>&1

and everything works normally if I do

mpdboot -n #nodes -f $PBS_NODEFILE
mpiexec -n #procs ./a.out

however if I attempt to use ssh instead of mpd as in

mpirun_rsh -np #procs -hostfile $PBS_NODEFILE ./a.out

I see the errors

Fatal error in MPI_Init:
Error message texts are not available
Fatal error in MPI_Init:
Error message texts are not available
MPI process (rank: 1) terminated unexpectedly on 
coates-e000.rcac.purdue.edu

Note that rsh/ssh itself appears to be working OK. Any help appreciated!

Thanks,
Bryan
