0.5.0

This release includes:

  • Bug fix for parallel_for_reduce on empty loops.
  • Make Chan.t and Task.promise injective #69
  • Add lockfree dependency #70
  • CI fixes (#73, #76)
  • Breaking change: Rename num_additional_domains to num_domains for setup_pool
  • Documentation updates (#80, #81, #82)

0.4.2

Includes Effect.eff -> Effect.t change from OCaml trunk. (#65)

0.4.1

This release fixes compatibility with OCaml 5.00.0+trunk in #61. Breaks compatibility with older Multicore variants 4.12.0+domains and 4.12.0+domains+effects

0.4.0

This release includes:

  • Usage of effect handlers for task creation. This introduces a breaking change; all computations need to be enclosed in a Task.run function. See #51.
  • Multi_channel uses a per-channel domain-local key, removing the global key. #50
  • Bug fixes in parallel_scan. #60

0.3.2

Corresponding updates for breaking changes introduced in ocaml-multicore/ocaml-multicore#704

  • Updated with the new interface Domain.cpu_relax
  • Domain.timer_ticks replaced with Mirage clock.

0.3.1

  • #45 adds support for named pools. This is a breaking change with setup_pool taking an optional name parameter and an extra unit parameter.
  • A minor bug fix in parallel_for_reduce.

0.3.0

This release includes:

  • A breaking change for Task pools where the num_domains argument has been renamed num_additional_domains to clear up potential confusion; see #31.
  • A new work-stealing scheduler for Task pools using domain local Chase Lev deques #29; this can improve performance significantly for some workloads.
  • A removal of closure allocation in Chan #28.
  • A move to using the Mutex & Condition modules for the implementation of Chan #24.
  • Various documentation and packaging improvements (#21, #27, #30, #32).

0.2.2

Updates to:

  • parallel_for to use new task distribution algorithm and allow default chunk_size (#16)
  • parallel_for_reduce to use new task distribution algorithm and allow default chunk_size parameter (#18)

0.2.1

  • recv_poll made non-allocating
  • Addition of parallel_scan #5

0.2.0

  • New Tasks library with support for async/await parallelism and parallel for loops.
  • Adds support for non-blocking Chan.send_poll and Chan.recv_poll.

Thanks to @gasche for API design discussions.

0.1.0
