I&#39;m writing a hybrid parallel program and it seems that unless I<br>
configure Open MPI with --enable-thread-multiple, then MPI_Init_thread<br>
always provides MPI_THREAD_SINGLE, regardless of what I pass for the<br>
required argument.<br>
<br>
Does this mean that I have to configure with --enable-thread-multiple<br>
even to use FUNNELED and SERIALIZED threads?<br>
