Provide a sane CPI mean calculation #74

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago

Currently the mean calculation for the statistics table of the CPI metric sums 
up over the CPI value. This produces wrong results.

Solution:

Sum up the raw events (instructions executed and cycles unhalted) and calculate 
CPI for the whole thread group.
