Benchmarks on c7g.16xlarge
thirtythreeforty opened this issue · 5 comments
I managed to get the benchmark suite to run on an AWS c7g.16xlarge instance running Ubuntu 22.04, built with Clang 15 (with Release build type), with the machine otherwise quiet. Benchmarks were done on 8dd4984 (current tip of tree).
See the attached log: results.txt
Fantastic, thank you! Did it output a bunch of .json
as well, maybe in the build directory? Bit easier to process than the text logs :)
These results look unbelievable, fib has almost a 128 times speed up!

Yep, here you go: json-results.tgz
How does a 64x thread increase translate to a 128x speedup?
Nice. The fib
benchmark in particular shows the scaling of the library when it's given a bunch of busy work.
If there are other experiments you want I'd be glad to run them, otherwise you can close this when you're happy with it.
