In the parallelism section of the guide (https://docs.racket-lang.org/guide/parallelism.html), there's a Mandelbrot set example demonstrating parallel computation with futures. I've tried it on two different machines (with OSX and Linux) but I don't seem to get any parallel computation. The futures visualizer shows very short "squares" of work with a sync-and-switch to the other thread on both machines. This pattern continues all the way to the end of computation. Both machines are using DrRacket 6.7. The first example with the for/list iteration works as described.
Has something about futures changed since the example was written? Is the problem in the example code or in Racket itself? I'd be happy to submit a PR with a fixed example, but I don't understand what's happening well enough to figure it out on my own. I tried to send this message with a screenshot of the futures visualizer a few minutes ago, but it was immediately deleted. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
