[mpich-discuss] MPI_THREAD_MULTIPLE

[Jayesh Krishna]

Hi,
 Are you trying the latest stable release, 1.1.1p1, of MPICH2
(http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=dow
nloads) ?
 Can you send us a test program ?

Regards,
Jayesh

Hey guys,

I need to call into the thread-safe version of MPICH2 so I tried to
initialize with MPI_Init_thread() and MPI_THREAD_MULTIPLE, but no matter
how I configured the channels on my nodes - tried both mt and nemesis -
that function returns MPI_THREAD_SINGLE as provided thread support.

I'm using 1.0.8p1 on Windows if that matters. Installed from the provided
MSI binary. Perhaps I need to build from sources, configuring it with
thread support?

Thanks
