Haskell vs. f# vs. scala

This paper provides a performance and programmability comparison of high-level parallel programming support in Haskell, F# and Scala. Developing several parallel versions, we employ skeleton-based, semi-explicit and explicit approaches to parallelism. We focus on advanced language features for separating computational and coordination aspects of the code and tuning performance. We also assess the impact of functional purity and multi-paradigm design of the languages on program development and performance.
