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. And since you are, no doubt, aggressively involved in high performance computing (HPC), I am sure you want to know also.

Meet Khang Nguyen and learn about analyzing power efficiency in apps. In his first blog, Khang provides guidance on what are the most common pitfalls in analyzing application power consumption and then he introduces his second blog that covers how to use the Windows Performance Toolkit in order to root-cause power issues.

Performance Monitor (perfmon) is a Windows tool used to view performance data.  Although the name of the tool implies that it is only for performance, it also provides useful information that can be used for power analysis. In this blog, I will talk about perfmon in Windows 8 and how to use it to determine, at a high level, if your application can be optimized for power. This version has additional information that is useful for analyzing power not found in previous versions of Windows.
