FWIW, usually you want to leave the default in place, which is "runtime".

I can reproduce your problem. I've filed a ticket for it: https://trac.mpich.org/projects/mpich/ticket/1787

Hello,

I'm trying to configure MPICH2 1.5 with the sock device and MULTIPLE thread support level.

At first I configured without specifying anything about threads (since on my MPICH2 1.4.x machines, using just --with-device=ch3:sock does seem to build with MULTIPLE support by default). But all I obtained was SINGLE.

So I tried to reconfigure the 1.5 release, now explicitly specifying --enable-threads=multiple, and got:

error: The device ch3:sock does not support MPI_THREAD_MULTIPLE

Yet on the README for the 1.5 release, I see:

--enable-threads - Build MPICH2 with support for multi-threaded applications. Only the sock and nemesis channels support MPI_THREAD_MULTIPLE.

Should this work? Any differences between 1.4 and 1.5 on this?

Thanks, Nicolás _______________________________________________ discuss mailing list [email protected] To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
