--
|
||
|
|
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. Please note that the current FLOP measurements on SandyBridge
|
||
|
|
are potentially wrong. So you cannot trust these counters at the moment!
|
||
|
|
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.
