Why don't you try running the binary generated by util/m5/m5.c in SE mode of gem5? I think so far you have not even tried to do anything at all on your own. Unless you try to get your hands dirty by writing and executing some code, I hardly think that you would be able to use gem5 to get any meaningful results. -- Nilay _______________________________________________ gem5-users mailing list gem5-users@gem5.org http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users
