| August 22, 2008 8:07 AM PDT AMD vs Intel numerics re-visited | ||||
Hello... I cannot get my managers to let go of this one. Last time I tested, my code compiled with IVF was giving me slightly different answers on AMD vs Intel CPUs. We did not have this issue with the CVF. Has Intel done anything recently to remedy this problem? Here's a quick guide to my compiler settings....Thanks! Nick
32-Bit · Fortran -> Optimizations -> Disable Optimizations (Release Configuration Only, mainstream versions of our code only). This option is due to 387 FPU, to be re-visited when compiling native 64-bit code. · Fortran -> Code Generation: Enable Recursive · Fortran -> Data: Initialize to Zero “Yes” · Fortran -> Floating point: FPE0 (crash on NaN) · Fortran -> Runtime: Generate Traceback, Check array and string bounds (this enables the DOS version to return the line and subroutine where the crash occurred). · Fortran -> Libraries: Ensure that “Multithreaded” is selected, not “Multithreaded DLL”; or, that “Multithreaded Debug” is selected, not “Multithreaded Debug DLL”. · Linker -> Enable Incremental Linking: No. (See “Traceback” above) | |||||
