Hi, I see what looks like a bug in openmpi involving the MPI_THREAD_MULTIPLE. When we call MPI_Init_thread with this argument, this 61-line example hangs:
http://www.slac.stanford.edu/~cpo/mpi_one_sided.cc There are some commented out lines in that file that we can use to workaround the problem. We use openmpi 1.8.1 configured like this: ./configure --prefix=%{instdir} \ --with-lsf=no \ --enable-mpi-thread-multiple I looked through the mailing list archives, and saw some posts that looked similar for version 1.7.1. Is this still a known issue for 1.8.1? Thanks for any thoughts... chris
