Profiling group to measure memory bandwidth drawn by all cores of a socket.
Since this group is based on Uncore events it is only possible to measure on
a per socket base. Also outputs total data volume transferred from main memory.
SSE scalar and packed single precision FLOP rates. Also reports on packed AVX
32b instructions.
The operational intensity is calculated using the FP values of the cores and the
memory data volume of the whole socket. The actual operational intensity for
multiple CPUs can be found in the statistics table in the Sum column.
