If we compile openmpi with support for posix threads (./configure --prefix=/usr/local --enable-mpi-threads --with-threads=posix), mpi hangs even with simple commands likempiexec --host localhost --np 1 hostnamelock up, and have to be killed. If we compile without the --with- threads=posix, it works fine. We've tried this with both 1.0.1 and 1.0.2a3 on a CentOS release 4.2 install (CentOS is the same as Redhat, built from the same sources,just without the trademarked name and the support), and on a Debian unstable install. Does anyone have any ideas on getting openmpi to work with posix thread support?
It looks like there was an inadvertent double-lock in the startup sequence for the standard I/O forwarding in our subversion branch for the 1.0 releases. I'm not sure how the problem snuck into the release branch, but it has been fixed. You can either get an SVN checkout of the 1.0 branch, get the nightly tarball build tomorrow, wait for us to release Open MPI 1.0.2, or apply the attached patch to the v1.0.1 tarball.
