Hi, I have the problem when I tried to simulate more than one core with "scons -Q c=4 config=./config/default.conf", and I was expecting to see simulation results for each of the four cores. However, the reported stats sim result (including the area/power results from McPAT) is only for one core. Really appreciate that if someone has any suggestions to solve the problem.
Many thanks!

If I use other machines like "-machine ooo_2_th", I will get the error as below: --------- server running on `127.0.0.1:5900' ::ERROR::Can't find 'ooo_2_th' machine generator. --------- Here is the whole command I use for running marss: simconfig -run -kill-after-run -stopinsns 100m -stats marss_result.txt -logfile marss_logfile.txt -machine single_core (or ooo_2_th) (2) For my second problem, since it works well if I set "-machine single_core", however, the resulting stats results are only for one core. I also tried to generate the power number with McPAT and it also only generates results for one core instead of for four cores. Is it because the machine single_core can only be used for a single core simulation (scons -Q c=1) ? I really appreciate if anyone can help. By the way, I use the ubuntu-natty.qcow2 disk image. Many thanks!!! Jolin -- There will be miracles when you believe!
