Cycles Per Instruction – Why it matters

To compare how one version of a part of the code is running to another version, since this is a ratio, it is important to keep one of the values constant in order to understand if the optimization is working. If more cpu cycles are being used, but more instructions are being executed, then the ratio could be the same, but this measure will not show any improvement. The goal is to lower the CPI in certain parts of the code as well as the overall application.

Intel Xeon Phi Memory Mode Programming (MCDRAM) in a Nutshell

James Reinders discusses one of the “mode” options that Intel Xeon Phi processors have to offer: memory modes. “For programmers, this is the key option to really study because it may inspire programming changes.”
