What CFlags are being used to optimize a Smithfield 830 Dual Core?

Hi ,

I am installing Gentoo on four Smithfield 830 Dual core servers. I was curious and interested to find out exactly, if any CFlags in GCC or ICC are used to optimize performance. I haven't found any published data to support optimization flags for the smithfield.

I would appreciate a information that can be posted on this thread.

Sincerely,

For more complete information about compiler optimizations, see our Optimization Notice.

Smithfield is the same as Nocona, as far as the issues dealt with by compiler flags are concerned. So, gcc -march=nocona is suitable, along with any other gcc flags you would normally use, including -ftree-vectorize. icc -xW or -xP would be chosen, according to the desired choice between Opteron compatibility and SSE3 optimization. For applications I have dealt with, the same optimizations work for dual single core Nocona and for single socket dual core Smithfield.
