Interesting issue. I have access to two Dell Precision M4300 workstation laptops. On both machines I installed my copy of Lahey Fortran Pro 5.5 (LF9555). I also have an old Dell Dimension D8300 desktop with the compiler on it.

What was the purpose of installing the compiler on each machine?

First M4300 came with a defective screen. Dell chose to send out a replacement system and have me return the original after I received the replacement.

This gave me the opportunity to determine that it was not a hardware issue as the problem occurred on both machines. As I indicated in my last post, Compaq Fortran behaves as expected - the M4300 is almost 3.5 times faster that the D8300 desktop. It thus appears to be a Lahey issue.

I understand why your are testing the speed of your application on the M4300 against the D8300 but why did you need the compiler? Surely you just needed to copy the already compiled test program from the D8300 to the M4300?

Did you re-compile on each computer with different settings?
