Abstract
Enabling programmers to “think parallel” is critical if we are to be able to effectively exploit future multicore/manycore architectures. This paper introduces paraforming: a new approach to constructing parallel functional programs using formally-defined refactoring transformations. We introduce a number of new refactorings for Parallel Haskell that capture common parallel abstractions, such as divide-and-conquer and data parallelism, and show how these can be used by HaRe, the Haskell Refactorer. Using a paraforming approach, we are able to easily obtain significant and scalable speedups (up to 7.8 on an 8-core machine).
