Pavan,

In both mpich2-1.3b1 and mpich2-1.3rc1, I'm still seeing a 
"mpiexec.hydra". In mpich2-1.3b1, hydra still seems to be working normally 
as it did for mpich2-1.2.1p1. However, for mpich2-1.3rc1, mpiexec.hydra is 
a script rather than a binary, and it doesn't work. Also in both 
mpich2-1.3b1 and mpich2-1.3rc1, the mpiexec link points to mpiexec.py, 
which is the mpiexec/MPD.

My configure options are

CC=icc
CXX=icpc
FC=ifort

MPICH2LIB_FFLAGS="-O3 -fpic"
MPICH2LIB_FCFLAGS="-O3 -fpic"
MPICH2LIB_CFLAGS="-O3 -fpic"
MPICH2LIB_CXXFLAGS="-O3 -fpic"
CFLAGS="-O3"
CXXFLAGS=$CFLAGS

module load intel64/11.1.072
export F90=""
RSHCOMMAND=/usr/bin/ssh
TVDSVRLAUNCHCMD=ssh
set +a
