Measuring RAPL values

On Linux you can use the "msr" driver available with most distributions. Run as root (or with sudo) or else have your sysadmin give you read permissions. See here for sample source code.

On windows you can see if the msr tool from IBM Performance Inspector works.

The RAPL values can be found in the Intel 64 and IA-32 Architecture Software Developer Manual Volume 3, found here. See section 14.7.1 (at least in the March 2013 manuals).
