As I should have said originally, I just did the -march=pentium4 -mfpmath=sse, I didn't change to a 64 bit system. Will that get the repeatabiility? It has on the brief test I did.
Right, if you specify sse, you get totally different floating-point accuracy semantics by limiting the precision to 64-bits (this has nothing whatever to do with being on a 64-bit machine) and it should give better reproducability.
Thanks, Mike.
