Hi,

Can anyone share the methodology for running multi-threaded programmes in
Gem5 FS mode with the Ruby memory model? To be specific, I am interested in
the PARSEC benchmark suite. I have the following doubt:

Let 'A' be a programme from the PARSEC suite. Let there be 8 cores in the
simulated Gem5 system. How can we execute 'K' (K = 8) threads of 'A' on 8
available Gem5 cores? Is 'K' configurable? Can we choose any value for 'K'?

Thanks in advance,
Aritra

Hi Aritra,

There is a parameter for parsec benchmark to choose how many threads to run program. It should be -n thread_num, here are some parsec examples: https://github.com/bamos/parsec-benchmark#more-examples.

For gem5, this parameter can be changed in configs/example/gem5_library/x86-parsec-benchmark.py.

Regards,

Congwu Zhang
