Hi Ravikant, If I understand your request, you are trying to run multiple processes (one on CPU, one on CPU+GPU) simultaneously. I have never tried doing this, and thus do not know how to make it work or not. My guess though is that gem5 does not support running multiple concurrent processes. Sorry I don't have better news; maybe someone else who knows more about this can help.
In terms of shared LLC: that is already done, effectively, with the directory between the CPU and GPU in apu_se.py. By default its size is 0B (i.e., it just acts as a directory, not a cache) but you can change the size.
