lparallel

lparallel is a library for parallel programming in Common Lisp, featuring

• a simple model of task submission with receiving queue
• constructs for expressing fine-grained parallelism
• asynchronous condition handling across thread boundaries
• parallel versions of map, reduce, sort, remove, and many others
• promises, futures, and delayed evaluation constructs
• computation trees for parallelizing interconnected tasks
• bounded and unbounded FIFO queues
• high and low priority tasks
• task killing by category
• integrated timeouts

See http://lparallel.org for documentation and examples.

Running

lparallel should run on any Common Lisp implementation supported by bordeaux-threads. The following implementations successfully pass the test suite:

• ABCL
• Allegro
• Clozure
• LispWorks
• SBCL

To run tests, load lparallel-test.asd and call (lparallel-test:execute).

To run benchmarks, load lparallel-bench.asd and call (lparallel-bench:execute N) where N is the number of worker threads.
