Formulas:
|
|
CPI = CPU_CLK_UNHALTED_CORE/INSTR_RETIRED_ANY
|
|
Local DRAM data volume [GByte] = 1.E-09*OFFCORE_RESPONSE_0_LOCAL_DRAM*64
|
|
Local DRAM bandwidth [MByte/s] = 1.E-06*(OFFCORE_RESPONSE_0_LOCAL_DRAM*64)/time
|
|
Remote DRAM data volume [GByte] = 1.E-09*OFFCORE_RESPONSE_1_REMOTE_DRAM*64
|
|
Remote DRAM bandwidth [MByte/s] = 1.E-06*(OFFCORE_RESPONSE_1_REMOTE_DRAM*64)/time
|
|
Memory data volume [GByte] = 1.E-09*(OFFCORE_RESPONSE_0_LOCAL_DRAM+OFFCORE_RESPONSE_1_REMOTE_DRAM)*64
|
|
Memory bandwidth [MByte/s] = 1.E-06*((OFFCORE_RESPONSE_0_LOCAL_DRAM+OFFCORE_RESPONSE_1_REMOTE_DRAM)*64)/time
