[mpich-discuss] MPI_THREAD_MULTIPLE

[Lubomir Radev]

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
