Hi,
I looked into the linux_ia64_ifort+mpi_ice_nas optfile and compared it 
to the one I used
for testreport and they are very similar, mine being a bit more 
standard. The only significant
difference is in the optimization :
FOPTIM='-O2 -align -ip -xSSE4.2' in mine
against
FOPTIM='-O3'     in linux_ia64_ifort+mpi_ice_nas

The -O2 is because I didn't see much a difference in speed compared to 
-O3 and
it is safer. The -xSSE4.2 is specific to the normal_N queue and should 
be replaced by
-xSSE4.1 for the normal queue (and it does speed up things in my case).

I can replace linux_ia64_ifort+mpi_ice_nas by my version, or we can work 
something out ?
What do people think?
david
