The Intel® Xeon Phi™ coprocessor: What is it and why should I care? Pt 1: Fitting it all on one slab of silicon
Hi, my name is Taylor Kidd.
So exactly which power states exist on the Intel® Xeon Phi™ coprocessor? What happens in each of the power states? Inquiring minds want to know.
Recently, while profiling a workload on the Intel® Xeon Phi™ coprocessor using Intel Vtune, I ran across the following error:

Intel® Xeon Phi™ coprocessor Power Management Part 1: P-States, Reducing power consumption without impacting performance
Right up front, I am going to tell you that P-states are irrelevant, meaning they will not impact the performance of your HPC application.
