Inconsistent Stream Bandwidth Measurements

Inconsistent Stream Bandwidth Measurements

Hi,I've been trying to root cause why I see huge run to run variation in stream performance. Running the same binary on the MTL machine with the same background load, I see a stream Triad score of either:Function Rate (MB/s) Avg time Min time Max timeTriad: 2400.5403 0.2000 0.2000 0.2001orTriad: 36019.3566 0.0151 0.0133 0.0431This is from an interactive login. I haven't tried this using the batch mode yet. This is the OpenMP version using 64 threads, though I've tried other thread counts as well.Does anyone have an idea as to what could be impacting my bandwidth by 15x run to run?Thanks
