Hi, I am running parsec on X86, using gem5-stable-07352f119e48. I am using the precompiled Parsec binaries and kernel images. I use 2 cores and 2 threads.I restore from a checkpoint (which was taken at the beginning of the ROI). I dumpreset statistics every total 10 million instructions (CPU0 + CPU1). However, i see that for some of the statistics, system.switch_cpus0.ipc is 'nan'. For these statistics, both the committed instructions and the numCycles are zero. This 'nan' IPC is observed periodically for the 2 cpu case. When i increase the number of cores and threads to 6, this issue becomes even more apparent (more frequently and for a larger number of the cores). I also had this issue when i was dumping stats based on time using the built in statDump function. Could you help me with this issue? Could it be a restore checkpoint issue, something with detailed CPU or about dumping?
Best, Fulya
