Widely used in academia in the 2010s and beyond. Countless papers must have been published with it.
The website went down in 2023, and Ciro Santilli added a data backup to cirosantilli/parsec-benchmark
Ciro Santilli's fork of PARSEC. This fork was made to improve the build system and better support newer targets, including newer Ubuntu and Buildroot.
After the PARSEC website died in 2023, Ciro Santilli also uploaded the test data to GitHub.
The interface is a bit annoying, but the tool is really cool.
100 cycles of matrixprod:
stress-ng -c1 --cpu-ops 100 --cpu-method matrixprod
man stress-ng gives the list of possible --cpu-method. It documents matrixprod as:
matrix product of two 128 × 128 matrices of double floats. Testing on 64 bit x86 hardware shows that this is provides a good mix of memory, cache and floating point operations and is probably the best CPU method to use to make a CPU run hot.
If you don't specify the --cpu-method it apparently loops through every method one by one.
Limit time to 1s instead of limiting cycles:
stress-ng -c1 -t1 --cpu-method matrixprod
