Power Management: So what is this policy thing?

Unlike a lot of previous recent blogs, this series is about power management in general. At the very end of the series, I’ll write specifically about the Intel® Xeon Phi™ coprocessor.

I have talked incessantly over the years about power states (e.g. P-states and C-states), and how the processor transitions from one state to another. For a list of previous blogs in this series, and well as other related blogs on power and power management, see the article at [List0]. But I have left out an important component of power management, namely the policy.

BKMs on the use of the SIMD directive

We had an ask from one of the various “Birds of a Feather” meetings Intel® holds at venues such as at the Super Computing* (SC) and International Super Computing* (ISC) conferences. The customer wanted to know BKMs (Best Known Methods) on the proper usage of the new OpenMP* 4.0 / Intel® Cilk™ Plus SIMD directive. I volunteered to create such a list. Investigating the topic more thoroughly, I discovered that there is already a vast amount of resources on vectorization and the use of the SIMD directive.

    Dear passionate power management reader,

    Doing an internet scan for material having to do with power management policy, my next blog series, I ran across a blog that I believe to be excellent. As many of you have discovered, I generally write at a pretty high level, though technical. I do this intentionally. At the beginning of my blogging career, there was not much written about power management that was comprehensible to a competent engineer who was not a power expert.
