Thread tree

A tree-structured thread pool. See API documentation for more information.

Stack jobs and job execution based on rayon-core by Niko Matsakis and Josh Stone.

Experimental simple thread pool used for spawning stack-bound scoped jobs with no work stealing.

This is good for:

  • You want to split work recursively in jobs that use approximately the same time.
  • You want thread pool overhead to be low

This is not good for:

  • You need work stealing
  • When you have jobs of uneven size

Wild ideas and notes

Possibly allow reserving a subbranch of the tree.

A hierarchical thread pool used for splitting work in a branching fashion.

This thread pool is good for:

  • You want to split work recursively in jobs that use approximately the same time.
  • You want thread pool overhead to be low

This is not good for:

  • You need work stealing
  • When you have jobs of uneven size
