# [JobGraphs.jl](https://github.com/nhz2/JobGraphs.jl)

This is a package to help use all the CPU cores when running multithreaded simulations or solvers. With `Threads.@threads` or OhMyThreads.jl, each parallel loop needs to spawn new tasks on each outer iteration. Loops that don’t depend on each other can’t easily overlap. [JobGraphs.jl](https://github.com/nhz2/JobGraphs.jl) lets you describe loops of parallel loops and their dependencies. This description can be planned and then run many times on a fixed number of worker tasks.

The package will be registered in a few days.
