This paper introduces a new programming methodology for intro- ducing and tuning parallelism in Erlang programs, using source-level code refactoring from sequential source programs to parallel programs written us- ing our new skeleton library, Skel. High-level cost models allow us to predict with reasonable accuracy the parallel performance of the refactored program, enabling programmers to make informed decisions about which refactorings to apply. Using our approach, we are able to easily obtain significant and scal- able speedups of up to 21.39 on a 24-core machine over the original sequential code.
