Hi Graham,
thanks for fixing it so fast! I have attached a 128 CPU (=32 nodes*4
CPUs) slog file that tests the OpenMPI tuned all-to-all for a message
size of 4096 floats (16384 bytes) where the execution times vary
between 0.12 and 0.43 seconds.
Summary (25-run average, timer resolution 0.01)
It looks like this message slipped by us -- sorry!
Open MPI does not yet support cygwin. The 1.0 series is essentially
restricted to bug fixes only, so it is unlikely that cygwin support
will be included there.
However, work is ongoing in the trunk for cygwin support. You might
