Thanks for the help. I'll use this patch as well as add some variability to my L2 misses and L1 misses, since I have the feeling most of my workloads can probably fit inside the caches I'm using for experiments.

Here is a diff to m5 that should do the trick. Just set latency_var = 'XXns' on the Physical Memory object and that should do the trick. It will still be deterministic for a given latency since the random number generator is seeded to the same thing (which is good so you can redo an experiment when you find the problem). Changing the latency_var parameter by a little bit is probably the best way to see a wide variety of results. Ali No virus found in this incoming message. Checked by AVG.
