Hello All, I have a gem5 X86 full system set up that starts with KVM cores and then switches to O3 cores once the benchmark reaches the region of interest. Right now I am testing with a simple multithreaded hello world benchmark. Sometimes the benchmark completes successfully while others gem5 just seems to hang after starting the benchmark. I believe it is still executing some instructions but without making any progress. The chance of this behavior ( indeterminism) happening increases as the number of simulated cores or the number of threads created by the benchmark increases.
Any ideas what might be the reason for this or how I can start debugging this problem? Note: I have tried the patch in https://gem5-review.googlesource .com/c/public/gem5/+/19568 but the problem persists. Thanks!
