Hi,
Using the kernel and disk images for PARSEC on x86, I try to run PARSEC on
X86 full system using the following command:
./build/X86/gem5.opt configs/example/fs.py -n 4 --l1i_size=64kB
--l1d_size=64kB --l2_size=8MB --num-l2caches=4 --topology=Mesh_XY
--cpu-type=timing --ruby --network=garnet2.0 --mesh-rows=2 --num-dir=4
--kernel=x86_64-vmlinux-2.6.28.4-smp --disk-image=x86root-parsec.img
--script=blackschole_4c_test.rcS
The simulation gives the following output:
==== m5 slave terminal: Terminal 0 ====
