<p>Is it possible that Microsoft will be able to make F# programs, either at VM execution time, or more likely at compile time, detect that a program was built with a functional language and automatically parallelize it better? </p>
<p>Right now I believe there is no such effort to try and execute a program that was ... | <p>I think this is unlikely in the near future. And if it does happen, I think it would be more likely at the IL level (assembly rewriting) rather than language level (e.g. something specific to F#/compiler). It's an interesting question, and I expect that some fine minds have been looking at this and will continue to... | <p>There's active research for autoparallelization and auto vectorization for a variety of languages. And one could hope (since I really like F#) that they would concive a way to determine if a "pure" side-effect free subset was used and then parallelize that.
