changeset 68a5b8bba293 in /z/repo/m5 details: http://repo.m5sim.org/m5?cmd=changeset;node=68a5b8bba293 description: inorder:regress: host-inst-rate improved ~58% there are still only a few inorder benchmark but for the lengthier benchmarks (twolf and vortext) the latest changes to how instruction scheduling (how instructions figure out what they want to do on each pipeline stage in the inorder model) were able to improve performance by a nice amount... The latest results for the inorder model process about 100k insts/second (note: 58% is over the last time run on 64-bit pool machines at UM)
