Dear gem5 users,
I’m doing SPEC CPU 2017 benchmarks within gem5 at the moment. I’m using the
fs.py system configuration using a NonCachingSimpleCPU (and did also runs using
the AtomicSimpleCPU) and DDR4 memory together with a disk image created using
the gem5-resources for the SPEC CPU 2017 benchmarks (see
https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/spec-2017/
<https://gem5.googlesource.com/public/gem5-resources/+/refs/heads/stable/src/spec-2017/>
) on X86 architecture. I did change the SPEC CPU 2017 version used from 1.1.0
to 1.1.8. I’m aware of a gem5art tutorial page about those benchmarks, which
also lists a table of results in the end (see
https://gem5art.readthedocs.io/en/v1.2.0/tutorials/spec2017-tutorial.html
<https://gem5art.readthedocs.io/en/v1.2.0/tutorials/spec2017-tutorial.html> ).
I’m aware the tutorial page does not relate to the gem5 release v22.1.0.0, but
I got several benchmarks with different errors, either during the benchmark
setup (input generator for 625.x264_s, hash mismatch on 657.xz_s), or during
the benchmark running (killed process without any output on 600.perlbench_s). I
did runs on those benchmarks using the AtomicSimpleCPU and caches configured,
but they ended the same. All the benchmarks were using the "test” workload, eg.
./build/X86/gem5.opt --outdir=m5out_x264_dram_test ./configs/example/fs.py
--cpu-clock 3GHz --kernel /path/to/x86-linux-kernel-4.19.83 --disk-image
/path/to/spec-2017-image --script script_x264_dram_test.rcS --mem-size 4GB
--cpu-type NonCachingSimpleCPU --mem-type DDR4_2400_8x8
Or
./build/X86/gem5.opt --outdir=m5out_x264_dram_test ./configs/example/fs.py
--cpu-clock 3GHz --kernel /path/to/x86-linux-kernel-4.19.83 --disk-image
/path/to/spec-2017-image --script script_x264_dram_test.rcS --mem-size 4GB
--cpu-type AtomicSimpleCPU --caches --l1d_size=32kB --l1i_size=32kB
--l2_size=256kB --mem-type DDR4_2400_8x8
with script_x264_dram_test.rcS containing:
625.x264_s test .
Is there a current status of working SPEC CPU 2017 benchmarks, or is there some
change needed to apply since the release of the gem5 resource?
Thanks a lot!
BR,
Markus
