I am a hobbyist programmer. I have written a program in Delphi 6
which does a lot of calculation. Most of the variables are either
double precision or extended precision.
The program runs fine on most of the machines I have tested it on. It
ran fine on:
1. 866 mhz Pentium 3 running Windows 98
2. laptop with an AMD 1.2Ghz running Windows XP home
3. 2.66 Ghz Pentium 4 running Windows XP Home
4. 3.2 Ghz Pentium 4 running Windows XP Pro
I have run it on two machines which were both IBM NetVista computers
Penitum 4 at 1.8 Ghz running Windows 2000 Professional and on both
machines small errors show up in the calculation almost immediately
and then after a few seconds the program blows up with a floating
point overflow.
The scenarios being run are identical in all cirucmstances so there
should be no difference at all in the results of the calculation. If
the calculation runs to the end it takes several days.
Does anyone have any experience that would tell where the problem is:
1. a bug in the 1.8 Ghz chip
2. a bug in Windows 2000
3. an incompatiblitly between Delphi 6 and Windows 2000
4. other?
Any solutions?
