Regent: A Language for Implicit Dataflow Parallelism

Hey, I've been following up on Legion and Regent quite a bit, excellent work there.

Do you have a set of benchmarks that others can reimplement to compare the approaches?

I've added Dataflow Parallelism to my own multithreading runtime[1] but I didn't had dataflow focused benchmarks yet, well I could add Cholesky Decomposition but it's quite involved.

I expect the people from TaskFlow[2] and Habanero[3] (via Data-Driven Futures) would be quite interested as well in a common set of dataflow parallelism benchmarks.

By the way if you didn't read the DaCe paper[4] you absolutely should, seems like the age of Dataflow parallelism and properly optimizing for data is coming.

Please correct me if I'm wrong, but I think all of those system only work inside of a single process. Legion/Regent support distributed multi-node multi-process execution both on supercomputers and in the cloud.
