Hi Duc, By passing a list of CPUs to the system.cpu (as in the attached Python script), you are creating a multicore CPU (CPU here refers to a core). Secondly, if your CPU has SMT enabled, you should be able to pass multiple processes to the workload option.
Btw, there is already a JIRA issue created for the problem you are running into: https://gem5.atlassian.net/browse/GEM5-803 -Ayaz On Mon, Nov 9, 2020 at 2:18 AM Đức Anh via gem5-users <gem5-users@gem5.org> wrote: > Hello all, > > I am trying to create a system having multiple CPUs by passing a list of > CPU to the system.cpu.
