But be aware that performance is a lot more complicated than just adding up latencies. So you'll have to do a lot of testing and experimentation. | |
| Jul 26, 2012 at 21:45 | comment | added | Palace Chan | what is a good way/resource to learn the strong points, latencies, and such of your processor? For example Xeon, or Sandy Bridge? I think it would help make better (albeit nonportable) optimization decisions. | |

| Jul 25, 2012 at 22:06 | comment | added | Palace Chan | Thanks! I wish I had seen this before. What is a complete SSCCE? Yea funcA and funcB are relatively small. It is a 2 cpu intel Xeon with 6 cores per cpu. | |
