SHORT CPU clock information
EVENTSET
FIXC0 INSTR_RETIRED_ANY
FIXC1 CPU_CLK_UNHALTED_CORE
FIXC2 CPU_CLK_UNHALTED_REF
METRICS
Runtime (RDTSC) [s] time
Runtime unhalted [s] FIXC1*inverseClock
Clock [MHz] 1.E-06*(FIXC1/FIXC2)/inverseClock
CPI FIXC1/FIXC0
LONG
Formulas:
Runtime (RDTSC) [s] = time
Runtime unhalted [s] = CPU_CLK_UNHALTED_CORE*inverseClock
Clock [MHz] = 1.E-06*(CPU_CLK_UNHALTED_CORE/CPU_CLK_UNHALTED_REF)/inverseClock
CPI = CPU_CLK_UNHALTED_CORE/INSTR_RETIRED_ANY
