Hi All,
After not being successful to simulate some parsec benchmarks in
APLHA_FS using inorder cpu, now I created checkpoints using
atomicSimpleCPU and then tried to restore with inorder cpu. I still get
the following assertion error:
gem5.opt: build/ALPHA/sim/simulate.cc:70: SimLoopExitEvent*
simulate(Tick): Assertion `curTick() <= mainEventQueue.nextTick() &&
"event scheduled in the past"' failed.
Program aborted at cycle 2262221921000
Aborted (core dumped)
I tried restoring using DeriveO3CPU and was successful. Why only inorder
cpu simulation gives lot of errors?
I am sure that kernel, disk img and even checkpoint directory being
pointed out correctly.
So, can anyone point me out what this assertion error means ?
Here are my build commands:-
* For original run and writing checkpoints
*build/ALPHA/gem5.opt configs/example/fs.py
--script=configs/boot/runscript_black.rcS -n 4*
For restoring checkpoint:
*build/ALPHA/gem5.opt --debug-flag=InOrderCPUAll,ExecAll
configs/example/fs.py --script=configs/boot/runscript_black.rcS -n 4 -r
1 --restore-with-cpu=inorder --caches*
And I enable InOrderCPUAll and ExecAll flags to see where its going
wrong in the trace.
Here is the debug trace:

Can anyone please point me out the error? Also, if this question is
redundant, pointing to some previous thread of this question would also
be helpful. Thank you.
