Hi everyone,

A short update.  This multi-processor, shared memory machine shows no performance change
with the code snippet above, when I set 'processor affinty' to 1.  I got the tip from,

http://www.open-mpi.org/faq/?category=tuning


and remain interested in the results anyone else gets / tips for improving push times.

Best regards,

Mark.
