i want to run parsec blackscholes in fs mode with simsmall inputs in gem5 with these configurations : --num-cpus=64 --num-dirs=64 --cpu-type=O3CPU --cpu-clock=2GHz --caches --l1d_size=16kB --l1i_size=16kB --l2cache --num-l2cache=64 --mem-type=SimpleMemory --mem-size=2GB --ruby --network=garnet --topology=Mesh_XY --mesh-rows=8 --link-width-bits=512. How do I achieve this? I have seen the x86-parsec-benchmark.py, do i need to make modifications on that? Can someone help me regarding this? Regards, Ojas
