I was ust about to ask you to try gfortran.
Here for the record if you wish to try ...
On my 8Gb Win7 64bit laptop, I use the gfortran compiler (4.8.0 from equation solution), the mpich2 1.4.1p1-win-x86-64.msi and the METIS form the download area -- and it works fine.
I could not compile on my other laptop, 2Gb WinXP 32bit, with Intel Fortran compiler and I assumed it was either because of 32bit or because of the RAM.
From what you were saying, it could actually have been the Intel Fortran Compiler itself ... I would have asked you try to download / install gfortran instead, and compile on your same system ...
Here is the link gfortran:
www.equation.com/servlet/equation.cmd?fa=fortran
from which you can download: gcc-4.8.1-64.exe
Here is the link to mpich2:
www.mpich.org/downloads/versions/
from which you can download: mpich2-1.4.1p1-win-x86-64.msi
And the METIS from our download area ...
If you have the time, it would be nice to compare performance (compilation and run)
Thanks for the feedback.
