I would like to use OpenFOAM o
 

I would like to use OpenFOAM on an IBM pSeries 690 parallel supercomputer with AIX compilers installed.
Questions:
1) Has anybody experience with OpenFOAM on such a system?
2) How good is the parallel performance of OpenFOAM on distributed and/or non-distributed memory machines and is it somewhere documented (would be usefull/neccessary for me to get an account and installation support on the machine)?

Thanks!
