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
