SHORT L1 compute to data access ratio EVENTSET PMC0 VPU_ELEMENTS_ACTIVE PMC1 DATA_READ_OR_WRITE METRICS Runtime (RDTSC) [s] time L1 compute intensity PMC0/PMC1 LONG Formulas: L1 compute intensity = VPU_ELEMENTS_ACTIVE/DATA_READ_OR_WRITE - These metric is a way to measure the computational density of an application, or how many computations it is performing on average for each piece of data loaded. L1 compute to data access ratio should be used to judge suitability of an application for running on the Intel MIC architecture. Applications that will perform well on the Intel MIC architecture should be vectorized, and ideally be able to perform multiple operations on the same pieces of data (or same cache lines).
