Hello Fayza, I think you can put m5op in SPEC2017 to mark where the actual benchmark application begins and switch the CPU after reaching there. The documentation of using m5op: https://www.gem5.org/documentation/general_docs/m5ops/ I tried to put m5op in specinvoke in SPEC2006 to exit the simulation right before the actual benchmark application. Here is the note I took for doing that: https://github.com/studyztp/some-notes/blob/main/m5op-specinvoke.md
