Measurement of Uncore events with likwid-mpirun #158

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago
For pure MPI codes measuring Uncore events currently does not work as every 
process measures the Uncore events independently.

The problem is that even if only one process measures per socket some kind of 
syncronization would be necessary across processes to get accurate measurements.
