Dear Kris,

Have you upgraded to ADF2004.01?

We were under the impression that we solved the 2 GB file limit problem
in this most recent version,
so you should even be able to run the job - or any job - on just 1 CPU,
if you have enough free disk space.

If our assumption is not correct, please send your output file as an
attachment to support_at_scm.com
which a description of your OS and hardware details.

An alternative, but not desirable, solution would indeed be to increase
the number of processes,
without increasing the number of CPU's. In principle, you could run an
artificial 32-process parallel
ADF job on 1 CPU. However, the license file limits the maximum number
of processes to the
maximum number of CPU's in your license.

So, please let us know (support_at_scm.com) if upgrading to ADF2004.01
indeed solves this problem.
Thank you.

Best regards,
Stan van Gisbergen
