Parallel Functional Programming: An Introduction

Parallel functional programming has a relatively long history. Burge was one of the first to suggest the basic technique of evaluating function arguments in parallel, with the possibility of functions absorbing unevaluated arguments and perhaps also exploiting speculative evaluation. Berkling also considered the application of functional languages to parallel processing.

Due to the absence of side-effects in a purely functional program, it is relatively easy to partition programs so that sub-programs can be executed in parallel: any computation which is needed to produce the result of the program may be run as a separate task. There may, however, be implicit control- and data- dependencies between parallel tasks, which will limit parallelism to a greater or lesser extent...
