Hi Sheng, I'm also using Joel's disk image to run PARSEC on M5 FS mode up to 64 cores. And it's running well with shared L2 caches.
I agree with Joel that your problem is caused by using a Linux kernel which only supports upto 4 cores. And here's some details of what I did. Hope it would be helpful: On M5's webside, there's a package with linux patches and PAL code for support up to 64 cores. http://www.m5sim.org/wiki/index.php/Download --> Full-System Stuff And there's also a description of why the default M5 kernel only support up to 4 cores in the Frequently_Asked_Questions. http://www.m5sim.org/wiki/index.php/Frequently_Asked_Questions --> How many CPUs can M5 run You could easily find the procedure of how to install the patches on M5's wiki webpage. Besides, the tech report on Joel's website has very clear description about all the problems you might face. http://userweb.cs.utexas.edu/~parsec_m5/TR-09-32.pdf I cannot think of other issues I have met off the top of my head. But I believe your simulation should work well after you follow above steps. Hope this would be helpful to you and other people who are using PARSEC on M5.
