Implementing boid flocking with OpenCilk

[behoppe]

Hi OpenCilkers. Several of us heard @libbyshoop present "boid flocking" as a Peachy Assignment at EduPar and thought it would be great to implement the HW in OpenCilk. (Libby's code is here.) Has anyone made progress on that yet (e.g. @cleiserson @timkaler @neboat @chenxuhao @kyle-singer )? Please let me/us know with a reply here, because I know that @libbyshoop is also interested in implementing boids with OpenCilk, and it could be helpful for boid-implementers to coordinate. Thank you!

Bruce, I looked over Libby's code. I don't see an OpenMP implementation, just the C++ one. I'd be happy to work with anyone who wanted to take on parallelizing it. Cheers, Charles — Charles E.

Thanks @cleiserson. Did you see #include "omp.h", omp_set_num_threads(params.threads);, and omp_get_wtime(); in Boids/OMPpsPlot/boids.c?
