You no longer have to do -Iharness/harness anymore when invoking like `ruby benchmarks/fib.rb`.
If your ruby's bundler is different from the saved result in `Gemfile.lock`, bundler autoswitches by starting a new process. When it does this it sometimes doesn't pick up the old LOAD_PATH and results in a LoadError. Switch to use `Bundler.setup`, which is a simpler process and uses the current bundler.
Ex: ./run_benchmarks sudoku --harness=ractor
Add JSON benchmarks: parse_float parse_string Add to ractor harness, make it possible to use gemfiles in different directories and make it easy to do so. This way we don't have to create directories for each benchmark. Improve run_benchmarks.rb, allow it to take a regular expression for --name_filters option Ex: $ WARMUP_ITRS=10 ruby run_benchmarks.rb --category=ractor-only --name_filters=/json/ Allow it to take --skip-yjit option to only run with interpreter.
To use, do: NO_VIEWER=1 HARNESS_CHAIN="vernier,ractor" ruby run_benchmarks.rb --harness=chain --skip-yjit psych-load This runs vernier profiling for a ractor benchmark. You can also use perf like this, but it's untested right now.
I just copied the code over to the ractor directory because it would too hard otherwise. You can run it with: $ WARMUP_ITRS=5 ruby run_benchmarks.rb --category=ractor-only --skip-yjit optcarrot
Measures time taken to acquire and release the GVL over and over. Right now it's quite a large overhead when we have a few ractors.
contains 2 implementatsion. One using Process.fork, the other using Ractors

I was also working on a ractor harness at the same time as Jean 😄
We can incorporate ideas from both imo.
