Hello Jia:
The thread support is `runtime' by default when no --enable-threads
option is specified.  When affinity is disabled, any requested thread
level will be returned.  When affinity is enabled, the library will
return MPI_THREAD_SINGLE.

I suggest that you configure without any --enable-threads option and
specify MV2_ENABLE_AFFINITY=0 at runtime.

Please see the following link for more information on this:
