[mvapich-discuss] hang in mpi_comm_create

[Dan Kokron]

I am using mvpich2-1.6rc3 on a large Linux cluster (see
http://www.nas.nasa.gov/Resources/Systems/pleiades.html for more
information about the cluster)

MVAPICH is configured as follows.
./configure CC=icc CXX=icpc F77=ifort F90=ifort CFLAGS=-fpic -DRDMA_CM
CXXFLAGS=-fpic -DRDMA_CM FFLAGS=-fpic F90FLAGS=-fpic
--prefix=/u/dkokron/play/mvapich2-1.6rc3/install.dbg --enable-f77
--enable-f90 --enable-cxx --enable-mpe --enable-romio
--with-file-system=lustre --enable-threads=default --with-rdma=gen2
--with-hwloc --enable-error-checking=all --enable-error-messages=all
--enable-g=all --enable-fast=none

The configure log is attached.

My application gets wedged on a call to MPI_COMM_CREATE.  It does not
matter if SHMEM collective are enabled or not.  Also attached are
summaries of stack traces from all MPI processes.

Any ideas on how to proceed in debugging this issue?
