Subject: [OMPI users] Performance/stability impact of thread support
From: Daniel Mitchell (dlm.bulk.messages_at_[hidden])

Hi everyone,

I've asked my linux distribution to repackage Open MPI with thread support (meaning configure with --enable-thread-multiple). They are willing to do this if it won't have any performance/stability hit for Open MPI users who don't need thread support (meaning everyone but me, apparently). Does enabling thread support impact performance/stability?
