Hi;

I am not sure this is relavent to your question. I do have an computational fluid dynamics application which solves fluid flow problems.

Recently I was able to run this code up to 2048 processors on the Indiana University's IBM e1350 BigRed cluster. I did use 1.2.3 version of the OpenMPI. I am happy about the preformance I did get. (I am using point-to-point sendrecv in this code).

Thank you

Cisco is not yet testing that large, but we plan to shortly start
testing at np>=128 (I'm waiting for an internal cluster within Cisco
to be setup properly).
