Non-halted Clockticks

Thread Specificity: TS

Non-halted clockticks represent the number of clockticks that a logical processor is neither in sleep nor halted. If a physical processor package contains more than one logical processor, this event enables the VTune(TM) performance Analyzer to count the cycles that a logical processor is actively executing instructions.

Non-halted clockticks can be used to calculate the non-halted CPI. This can be interpreted as the inverse of the average throughput of a logical processor, while the logical processor is executing instructions.

If a physical processor package contains only one logical processor, non-sleep clockticks is essentially the same as non-halted clockticks.

See Counting Clock Cycles for information on the difference between non-sleep clockticks and non-halted clockticks.
