I am trying to compile and execute the CALMET/CALPUFF modeling system on a linux box, but cannot seem to get the same results I do within windows. I have read some of the tips about precision, and tried most of them, to no avail. Here in a nutshell is what I’ve gotten:
AMD 2600+ - Windows 2000 - compiled with Compaq Visual Fortran - gives a result of 78.320.
Same machine as above - compiled with PGF 5.2-2 - gives a result of 78.320.
Intel P3 550 mHz - RedHat 8.0 - compiled with PGF 5.2-2, pgf90 -tp p6 -pc 80 - gives a result of 77.822.
I have tried many different switch combinations, all to no avail. It just wants to give me 77.822. Any ideas?
