Sorry, I'm out of town right now, I'll send the input file to you
directly as soon as I return home.

No, it's a parallel version compiled with intel MPI 3.1 and sequential
MKL (libmkl_intel_lp64, libmkl_sequential and libmkl_core). The header 
part of my pw output indicates definitly that it's a parallel run.

The job scales quite well with just one pool, with efficiency from 92% 
on two cores to 74% on 8 cores, same tendency coincident with Intel's 
nehalem beta version.
