I did that. There are some differences and I attached them. In short, I see this:
old: children=dcache dtb icache itb tracer workload new: children=dcache dtb icache interrupts itb tracer workload Also the commitwidth, fetchwidth and some other parameters are 8 in the new version, but they are 4 in the old version. So I really wonder why it has a very low IPC. I will be greatly thankful if someone else try that. Also, I emailed another problem at http://permalink.gmane.org/gmane.comp.emulators.m5.devel/14987 about "Unable to find destination for addr" which I encountered in the new version. Appreciate any idea. >I believe the 'dotencode' message just means you should upgrade to a newer version of mercurial. ok I will try that. -- // Naderan *Mahmood; On Sun, Apr 15, 2012 at 3:45 AM, Steve Reinhardt <[email protected]> wrote: > I believe the 'dotencode' message just means you should upgrade to a newer > version of mercurial. > > > On Sat, Apr 14, 2012 at 10:36 AM, Mahmood Naderan <[email protected]>wrote: > >> I forgot to say that I removed the 'dotencode' feature and the "hg heads" >> says: >> >> mahmood@tiger:gem5$ hg heads >> changeset: 8920:99083b5b7ed4 >> abort: data/.hgtags.i@b151ff1fd9df: no match found! >> >> >> On 4/14/12, Mahmood Naderan <[email protected]> wrote: >> > For the old one, I use: >> > build/X86_SE/m5.fast configs/example/cmp.py -F 20000000 --maxtick >> > 10000000000 -d --caches --l2cache -b h264_sss --prog-interval=1000000 >> > >> > for the new one I use: >> > build/X86/m5.fast configs/example/cmp.py --cpu-type=detailed -F >> > 20000000 --maxtick 10000000000 --caches --l2cache -b h264_sss >> > --prog-interval=1000000 >> > >> > I attached the configs and stats.
