Hey guys,
I'm trying to run v8 benchmark (console) using gem5 (fs).
With the functional model everything seems to be fine.
Benchmark was executed correctly and I got all the required statistics in about
15 minutes or so.
Then I wanted to switch to the performance model (arm_detailed) but got some
issues there.
To estimate the running time I simply divided the total number of simulated
instructions I got from the functional model by the performance model's
instruction rate I got from the different benchmark (around 50k/s). That
shouldn't be absolutely correct but seems to be enough to get some estimation.
This calculation gave me the running time around 24 hours which is fine.
Unfortunately around 2 weeks already passed but the benchmark didn't finish yet.
It seems to me that something went wrong and the simulator is executing the
infinite loop or something (because even the trivial printf in the very
beginning of the benchmark was not printed yet).
Did someone ever met the same behaviour with v8 benchmark or some other
workload?
What is the best way to debug this issue? Printing pc seems to be very ugly
idea because the benchmark is huge.
Is the instruction rate (50k/s) I got is correct for the performance model?
Many thanks,
Orangeade
