Hello Debiprasanna,
Since you did not specify which level you are talking about, how you are
measuring zero data, system config, etc, I cannot give you a precise answer,
but these results seem incorrect to me. Have you tried using BDI and CPack,
which are present in your version, to verify if the amount of Zero (BDI), or
PatternZZZZ (CPack) match your results?
My runs of SPEC 2017 with FPCD indicate an average of 36% of data passing
through L3 is composed of zeros (90%+ of these were ZZZZ, and the rest a
mixture of XXZZ, XZZZ, ZXZX, ZZXX, ZZZX). Notice that this is a very
rough/quick estimate using geometric mean of non-normalized data. On leela, the
arithmetic mean of the checkpoints indicates that 48% of the compressed
patterns are zeros (the patterns given above; ZZZZ is 55% of that). On
deepsjeng the arithmetic mean of the cpts indicates that 83% of the compressed
patterns are zeros (the patterns given above; ZZZZ is 89% of that).
Regards,Daniel

Hi Debiprasanna,
I can't answer your question about compression. However, if you'd like to
contribute, please check out the CONTIRUBTING.md document.
I'm not sure exactly what your script does, so it's hard to say where the best
location would be. Possibly in configs/ if it is a configuration or a runscript
or in util/ if it's just scripts to run gem5.
Cheers,Jason

Hi All,
I am trying to evaluate the percentage of Zero Compressed data with Spec2017 on
gem5 revision-603f137. I observe that most of these benchmarks have extremely
high percentage of zeros.Even some benchmarks like leela and deepsjeng show
that 100% of the data is zero. The simulation was done at multiple regions of
interest.Is the model accurate or there are some issue? I would also like to
contribute the python script I have written to run SPEC2017 to gem5. Please let
me know how do I do it.
