AMD Athlon 1000 and Asus A7V suitable for CFD?

You are not using the same OS on the two machines, this could be the source of your problem. (Even though, WinNT and Win2000 are very similar).

The best thing to do is to recompile the code.

Sebastien, I successfully ran this code, compiled under WinNT, on a third machine with Win2000. But I will recompile and try again for new machine.

I have solved this problem. It seems that the PC133 RAM is required to run CFD jobs with this hardware configuration, eventhough, the ASUS manual specs allows for PC 100 RAM. I ran 330 iterations with a grid of over 3.6million grid points. A quick scan of the end iteration shows the same residual values. The 1.1Ghz Athlon completed this job about 2.7x faster than the Gateway with the PIII 450Mhz and cost about 1.75x less cost (not considering the 1998 dollar cost of the Gateway system).
