Hi, This is the information I got from running it in gdb:
Switch at curTick count:10000 info: Entering event queue @ 19318968082000. Starting simulation... gem5.opt: build/ARM/sim/simulate.cc:66: SimLoopExitEvent* simulate(Tick): Assertion `curTick() <= mainEventQueue.nextTick() && "event scheduled in the past"' failed. Program received signal SIGABRT, Aborted. 0x0000003127430285 in raise () from /lib64/libc.so.6 It seems that it failed at the assertion. Do you have any idea what's wrong with it? Thanks!

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. The command line and output is as follows: command line: build/ARM/gem5.opt --outdir=bbench2 configs/example/fs.py -b bbench-gb --kernel=vmlinux.smp.mouse.arm --frame-capture --checkpoint-dir=bbench -r 1 --caches --cpu-type=arm_detailed --l2cache --cacheline_size=64 --l1d_size=32kB --l1d_assoc=4 --l2_size=512kB --l2_assoc=8 Global frequency set at 1000000000000 ticks per second info: kernel located at: /tigress-hsm/fangfeil/gem5/system/binaries/vmlinux.smp.mouse.arm Switch at curTick count:10000 info: Entering event queue @ 19318968082000.

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.
