Dear forum participants,
Are there any benefits from upgrading from Inel Pentium 4 3GHz to Pentium D processor on 32bit windows platform? Would it be possible touse both processors from fortran program built by IVF?
Thanks in advance, Yuri

Yes, absolutely. You would want to add threading to your program, either through the auto-parallel option, or by use of OpenMP. A single-threaded application would not see an improvement (though background tasks on your PC would show a benefit from dual cores.)

The benifits returned depend on your application, your willingness to examine and change your program and the environment in which your program runs.

Look at the OpenMP documentation in the IFV user's guide.

If your application is compute intensive and if the algorithms are good candidates for parallelization then your application may benifit from OpenMP. This assumes your willingness to make some minor changes to your code.

If your application runs in conjunction with other applications then you will notice an immediate benifit without any programming effort.

There is a little bit of a learning curve to learn how to best use OpenMP. There is a forum here on Threading to help you get going.
