Good morning all,
I am attempting to measure the performance of the ARM HPI model
shipped with gem5 (in SE mode) using the XSBench
(https://github.com/ANL-CESAR/XSBench) benchmark program.
gem5 appears to exit normally ("existing with last active thread
context @ n") without the benchmark completing (XSBench prints
benchmark results to stdout that are not present).
I am using gem5.opt 2.0 with the command-line `build/ARM/gem5.opt
configs/example/arm/starter_se.py --cpu="hpi" --num-cores=1
--mem-size=8GB ~/XSBench/src/XSBench`.
I don't have a core dump, stack trace, or source code location (e.g.
if an assertion was violated) that I can use, and the simulation takes
several days to reach the failure point, which appears to be in the
main benchmark loop
(XSBench/src/Simulation.c:run_history_based_simulation()), so I can't
step through it in GDB. What can I do to debug this?
Cheers,
Grant Vesely
