Igor,

I plan to make the tests you are refeering to  available - together  with 
others- for benchmark purposes.

The use of the OpenMP on top of MPI - for example- it works  well on JS20 
Myrinet connected clusters
(e.g. MareNostrum) if you want to push the scaling to the 1000 processors 
regime.
In any case - I have already written the main reasons to use the dual 
parallelism in my earlier note.


BTW  The report  ( by Prof. Hutter and myself) is now published in 
Parallel Computing  (31)  1 (2005).


Best REgards,
