Dear Adrian,
I don't think it is an MPi problem. It is more likely that the head  
calculation (head.x) crashes for some reason while MPI is just reporting  
the crash. Please have a look at file si8_ph_head.out in the HEAD/  
subdirectory of the example. By "have a look" I mean: open the file with a  
text editor, and possibly send a copy to this mailing list.

best regards
