A program is bulit under Intel Fortran 9 usingVisual Studio.NET 2003. When running, Windows Task Mgr. shows 4 processors, but only 25% total CPU use. On another machine with an older Pentium chip the same program shows 100% CPU use, and runs faster. Is there some project setting I am missing?

You must build your application for multi-core processing in order to take advantage of it. This is the purpose of the options /Qparallel or /Qopenmp.
