I tried several different configurations. It works in atomic mode even with caches. But segmentation fault occurs for both arm_detailed and detailed cpu type. The checkpoint is taken in atomic mode. Should the checkpoint be taken with the same cpu type as it runs by restoring the checkpoint?

I tried to run the benchmark again and now it can run to completion. Thank you very much for your kind help! I have another problem. I took a checkpoint after booting the OS in atomic mode with the default configuration. I did this by inserting a m5 instruction in the bbench-gb.rcS file: /sbin/m5 checkpoint (right after sleep 10). The checkpoint can be taken correctly. Then I want to resume the checkpoint and simulate BBench in arm_detailed mode, but I got segmentation fault.

It's doing a google search for something called ewbay and the keyboard is open, that shouldn't happen. Were you interacting with the vncviewer with the mouse? Is it possible that this query could have been entered in error? There is nothing in the BBench source called "ewbay", so it's hard to tell how that url is being produced otherwise. -Tony On Sat, Sep 29, 2012 at 2:15 PM, Fangfei Liu <fangf...@princeton.edu<mailto:fangf...@princeton.edu>> wrote: Thanks for your reply.
