John, MPD has been deprecated for a long time and got completely deleted since MPICH 3.1.1. I guess mpiexec at <somedir>/Contents/engine/bin/mpiexec comes from an old MPICH that uses MPD. The version you compiled should have been built by default with the Hydra process manager but it was installed in a different folder (/somedir/mpich-3.0.4-shared) than the one showing bugs. You can change your environment to prioritize loading /somedir/mpich-3.0.4-shared over <somedir>/Contents/engine/bin/ or wipe out the MPICH installation in the latter folder. To make sure that MPD is not being built, you can specify --with-pm=hydra during configure or just use a more recent MPICH version >= 3.1.1 or the most recent MPICH 3.2. --Halim www.mcs.anl.gov/~aamer On 4/28/16 5:42 PM, JR Cary wrote:

One of our users saw:

Traceback (most recent call last):

Anyone seen this before?

mpich-3.0.4, compiled with

../configure' \ --prefix=/somedir/mpich-3.0.4-shared \ --enable-shared \ --disable-static \ CC='/usr/bin/gcc' \ CXX='/usr/bin/g++' \ FC='/usr/bin/gfortran' \ F77='/usr/bin/gfortran' \ CFLAGS='-pipe -fPIC' \ CXXFLAGS='-pipe -fPIC' \ FFLAGS='-fPIC' \ FCFLAGS='-fPIC'

mpiexec is a softlink to mpiexec.hydra.

Thx....John Cary
