Re: Is ^{:once true} still necessary for lazy-seqs?

^:once is absolutely needed for lazy seqs, because it allows the closed-over variables to get cleared while the lambda is *still running*, rather than waiting for it to finish. You can see the difference in this repl session: user> (let [x (for [n (range)] (make-array Object 1)), f (^:once

all true. Also, if you look at the internal structure of PersistentVector (perhaps using me seqspert lib - announced this evening), you would see that PersistentVector is actually implemented as a tree. Recombination through several levels of supervec could simply be thought of as extending thi

Re: fast parallel reduction into hash-set/map

I did give this some thought :-) Reading the code for subvec, it looks like if you try to take a subvec of a subvec the top subvec cuts the intermediate subvec out of the process by recalculating a new projection on the underlying vector, relevant to the offsets imposed by the intermediate sub

Re: fast parallel reduction into hash-set/map

Hey Jules, Really nice stuff your making! One note about your SuperVecs idea though, it seems that using that approach we could get a deeply nested tree to represent our a vector, and I think this is the exact thing vectors are trying to avoid.. On Friday, February 21, 2014 1:39:56 AM UTC+2,

Re: fast parallel reduction into hash-set/map

Hi, Andy. No I haven't - Thanks for the pointer - I'll take a look. I have a very specific usecase - the speeding up of the re-combination of the results of parallel reductions. I've found that the cost of this recombination often impacts badly on the overall timing of such a reduction, but wi

Re: fast parallel reduction into hash-set/map

Have you looked at core.rrb-vector, which implements Relaxed Radix Trees for vectors that implement subvec and concatenating two arbitrary vectors in O(log n) time? https://github.com/clojure/core.rrb-vector Unless I am missing something, the fast concatenation is what you are trying to achie

Re: fast parallel reduction into hash-set/map

So, having broken the back of fast re-combination of hash sets and maps, I wanted to take a look at doing a similar sort of thing for vectors - another type of seq that I use very heavily in this sort of situation. Let's see the cake first: seqspert.vector=> (def a (into [] (range 1000)))

Sorry for the short answer I am writing this on my phone. I am also using org mode and the following works fine for me: 1 evaluate the first block. Now cider should already be in the right namespace. 2. The next source block can be evaluated in the current ns. You basically have to make sure that t

(Dave and I work together). I suspect it will be easy to come to a reasonable license. My own preferences would be EPL or MIT, and EPL only because it's common in the community. Beyond that, something like chord isn't actually the big problem in a scheme like this. The real issue is ensuring
