In order to get the cache hit/miss threshold, I will the calibration tool to measure that. I will get different results from multiple runs(randomly ranging from 145 to 250). And at the same time, the problem remains even if I use taskset to run the calibration on a fixed core which is isolated from kernel(use isolcpus in grub file to isolate a cpu that will not be scheduled by other process). So have you ever met with problem that multiple runs of calibration produce different results?
