If we compile a program that generates mathematical results on an INTEL CPU and a end user runs it on a AMD CPU, could they get different results? Is the floating point calculations different? We have a end user who is getting different results than us. THey are using RedHat Linux Enterprise 6.1 on a AMD Opteron CPU. We have tried openSuse, RedHat Linux Enterprise 6, and Windows 7 on a INTEL CPU, and all three get the same resluts but different than the end user.
