[gem5-users] Dumping stats into individual files

Hi, I am using gem5 se.py to run some simulations. Is there a simple way to dump the stats into different files each time I call m5_dump_stats(…)? I.e. I want the stats files to be organized as stats.1.txt, stats.2.txt, … instead of one monolithic stats.txt. Thanks! Subhankar Pal | PhD

Thank you, Ciro. Turned out that by disabling most of the (classic) cache stat handlers, I was able to free up a lot of memory. Subhankar Pal | PhD Candidate, CSE | University of Michigan On March 25, 2020 at 4:38:52 AM, Ciro Santilli (ciro.santi...@gmail.com) wrote: I would try to put

Re: [gem5-users] Device size vs. Address Range Assigned

Hi Muzamil, It probably means that the size of your memory divided by the number of memory devices is 256 MB, whereas the device_size of your memory is 8 MB. You need to make sure that these two number must be equal. - Subhankar On March 28, 2017 at 3:39:53 PM, Muzamil Rafique (

Hi, Is there an better way to turn off cache coherence in the classic memory model, than to hack the code in src/mem/cache/? I know that that there exists a noncoherent XBar model, but couldn’t find an equivalent for caches. Thank you! - Subhankar ___
