Hi,
I'm doing a Fedora package of GROMACS. Does GROMACS have runtime CPU
capability detection, i.e. if the package is compiled on a SSE-capable
processor and run on an i586 (hope not), will it work?
Yes it does. It should work, but e.g. debuggers tend to dislike illegal
instructions (when e.g. testing for 3DNow on a pentium).
The safe way is, of course, to disable all assembly loops, which would
hurt performance a lot...
