This is just a follow-up of the few messages between me and Axel  
about the problem on the CRAY experienced running the input
cp2k/tests/QS/H2O-32.inp  (maybe interesting for people following  
this discussion):

On our CRAY it's working both with
pgi-6.1.4 and pgi-6.2.5 and pgi-7.0.4

it works also with


NO way to get cp2k working with gfortran..

This is the arch file I'm using for pgi:

ACML 2.6
# Note: PGI 5.2.* and 6.0.1-4 are not working due to compiler bugs.
# Note: The -g flag is needed for unknown reasons.

Are you running the 8 procs on 4 nodes  (is it a dual core?)..
Could it be a memory problem? any message from the error file?
If it's a dual core run try to run 8 (1 per core) forcing yod with - 
SN just to check
if it's really a memory problem..
