[Beowulf] Sempron compile optimization

[Alan Ward]

Hello everybody.

Since 64-bit CPU architecture is cheap these days in a Semperon (3000+ version), I've been trying to optimize some of my C code. As for compile switches on the gcc, do

   -march=x86-64 -mfpmath=sse -m3dnow

look reasonable? Any reason why the -m64 switch does not work for me?

Best regards,
Alan Ward
