Hello,

I could tell something ...

In principle, Yes. 
You could refer to "~ABINIT/Machine_dept_files/Intel_P6/memo.fujitsu_paral".
The specification of the machine is described on
       http://www.abinit.org/ABINIT/bench2.1.html
(The information appears a bit obsolete ... Still it might be helpful.
 Some update would be highly appreciated.) 
Of course, the options for MPICH should dependent on your compiler ...

I heard that the version of MPICH could be relevant for a code,
so that another MPI (LAM-MPI) might also be a candidate.

I am also interested in such information ...

I have not yet tried AMD, so any information would be appreciated...
(I heard that heat from AMD would become very hot ! Anybody here
 has such information ?) 

Hope this helps ... Someone could follow this topic.
