Hi,
we are building a rather complex simulation software, and have just switched to the Intel compilers as, hopefully, sole compiler to get rid of all others we use.
To do this, we are recompiling all our code using the intel visual fortran and c++ compilers, just bought.
Now, most of our code works well, but I just found out that one of our .dll-libraries (including c++ and fortran code, almost only fortran), fails to run on AMD processors. We have tried both older chips and newer, and it crashes the program on both occasions. So something is going wrong.
The code crashes identically both with optimization turned on or off, and the code runs on all Intel-computers we have found so far.
My question is: are there any known problems one should be aware of when compiling to AMD-chips?
Best regards,
Andreas

I previously ran into some issues with AMD

boiled down to using the option: /Qimf-arch-consistency:true
