parallel-tasks

This library is useful for running a large amount of parallel tasks that run on top of the IO monad, executing them in batches from a work queue. It has several features aimed at monitoring the progress of the tasks and tries to be reasonably efficient (in space and time) for large numbers (millions) of tasks. There is also caching support available so that the results of running the task can be preserved between runs of the same program, which is useful for doing scientific analysis.
