This is a component that exports power information for Intel Xeon Phi cards (MIC).

The component makes use of the MicAccessAPI distributed with the Intel Manycore Platform Software Stack.

(http://software.intel.com/en-us/articles/intel-manycore-platform-software-stack-mpss)

Specifically in the intel-mic-sysmgmt package.

A configure script allows for non-default locations for the sysmgmt sdk. see ./configure --help

About the data, PAPI retrieves the data via the MicGetPowerUsage call.

Per the SDK documentation:

MicGetPowerUsage - Retrieve power usage values of Intel® Xeon Phi™ Coprocessor and components.
