Modify runAllBenchmarks proc in run_benchmarks.nim to the desired parameters and variations.
Then run it:
nim c -r run_benchmarksBy default all circuit files for each combinations of circuit args will be generated in a unique folder named like: benchmarks/circuit_bench_depth32_maxslots256_cellsize2048_blocksize65536_nsamples9_entropy1234567_seed12345_nslots11_ncells512_index3
Generating the circuit files often takes longer than running benchmarks, so caching the results allows re-running the benchmark as needed.
You can modify the CircuitArgs and CircuitEnv objects in runAllBenchMarks to suite your needs. See create_circuits.nim for their definition.
The runner executes all commands relative to the repo. This simplifies finding the correct circuit includes paths, etc. CircuitEnv sets all of this.
