Hi Andrew,
In your distribution of ompi, do you include versions of ompi to support
different MPI thread
I believe we did this in the trunk to try and force thread-safety
implementation, but I don’t believe it was intended to transition to the
release branch. The only thread-related requirement on the release branch is
that libevent be configured with thread-support.
Anyone know of a reason why mu
Hi Andrew,
In your distribution of ompi, do you include versions of ompi to support
different MPI thread safetylevels? In particular, do you include a library
which supports MPI_THREAD_MULTIPLE?
Just trying to better understand the requirements of you ompi package in
terms of MPI thread safety.
Hi,
I'm reporting a performance (message rate 16%, latency 3%) regression when
using PSM that occurred between OMPI v1.6.5 and v1.8.1. I would guess it
affects other networks too, but I haven't tested. The problem stems from the
--enable-smp-locks and --enable-opal-multi-threads options.
