Re: Advice getting started with concurrency and parallelism in Clojure

I found the introductory talk on Claypoole pretty informative with regards to parallelism in Clojure in general: https://www.youtube.com/watch?v=BzKjIk0vgzE On Thursday, April 7, 2016 at 5:09:39 PM UTC+2, Mars0i wrote: > > Niels-- Ah, interesting. My uses of pmap haven't been I/O bound. I > d

Niels-- Ah, interesting. My uses of pmap haven't been I/O bound. I didn't know about the claypoole library. Will keep that in mind. On Thursday, April 7, 2016 at 8:00:39 AM UTC-5, Niels van Klaveren wrote: > > The biggest problem with pmap I have is ordering, ie. it will process in > batches

Re: Advice getting started with concurrency and parallelism in Clojure

Exactly. Clojure's strength is constraining mutability. How each primitive constrains mutability is different. Note: that many of these defaults can be overridden if the user really knows what they are doing. atoms - given a mutable cell, provide a function to update the data, may be run multiple

Re: Advice getting started with concurrency and parallelism in Clojure

The two resources that helped me most with concurrency and parallelism are "Java Concurrency in Practice" and "ZeroMQ — The Guide". Introductory Go books are also enlightening. Once you have a clear understanding of the underlying concepts in general, understanding how they are accessible in Cloju

Re: Advice getting started with concurrency and parallelism in Clojure

The biggest problem with pmap I have is ordering, ie. it will process in batches of (+ 2 (.. Runtime getRuntime availableProcessors)), and only take a new batch when the slowest of the old batch has been evaluated. With functions dependent on IO, parallel gains are only a fraction of what they

Re: Advice getting started with concurrency and parallelism in Clojure

Maybe people forget about pmap , pcalls , and pvalues because they're just too easy. On Tuesday, April 5, 2016 at 8:51:59 PM UTC-5, tbc++ wrote: > > If it all seems

Re: Advice getting started with concurrency and parallelism in Clojure

If it all seems confusing, do not despair, there's two things that will handle the vast majority of the use cases you may have: 1) `future` - spawns a thread that runs the body of the future ( https://clojuredocs.org/clojure.core/future) 2) `atom` and `swap!` - Used to store data that needs to be
