Subject: [OMPI users] [threads] How to configure Open MPI for thread support
From: Daniel Mitchell (daniel.lewis.mitchell_at_[hidden])

Hi everyone,

I'm writing a hybrid parallel program and it seems that unless I
configure Open MPI with --enable-thread-multiple, then MPI_Init_thread
always provides MPI_THREAD_SINGLE, regardless of what I pass for the
required argument.

Does this mean that I have to configure with --enable-thread-multiple
even to use FUNNELED and SERIALIZED threads?
