Hi Jules, I've just been hacking on OpenCL a bit the last few days[1] - Rootbeer was an inspiration after seeing it a few weeks back. I'm not trying to go down the Rootbeer route myself, but the idea of having (cl-map f ...) is one direction one can take it (I've been looking a bit at Haskell's Accelerate[2]).
I've mainly been trying to get my head around the programming model, at this point there's only a few simple macros that "compile" Clojure to OpenCL and pushes sequences back and forth. cheers, Hakan [1] https://github.com/hraberg/sleipnir [2] http://www.cse.unsw.edu.au/~chak/project/accelerate/ On Sunday, 2 September 2012 23:48:29 UTC+1, Jules wrote: > > > Guys, > > Has anyone read about RootBeer - https://github.com/pcpratts/rootbeer1 > > My understanding is that it can compile Java bytecode -> CUDA GPU code. > > A Java class that you want to run on your CUDA GPU must subclass the > RootBeer Kernel interface. > > So, I wondering what would happen if I > > 1) implement Kernel with some simple Clojure code that just e.g. adds a > couple of numbers, get the class out onto disc, compile it with the > Rootbeer compiler and try running the result on my GPU. > > 2) Pull the RootBeer compiler into a running Clojure image and figure out > how to do the same thing on-the-fly. > > 3) Write e.g. (cuda-map f coll) which embeds f in a Kernel, copies the > contents of coll and the new kernel up to your CUDA GPU and executes f on > the contents of coll in parallel producing a new coll which is copied back > into Clojure world and returned... > > Of course, there are lots of things to be resolved here, I have only had > time today to Compile up the CUDA download, clone the RootBeer git repo, > compile it and try to run the example program - ArraySumApp. I got an error > which I am thinking indicates that RootBeer doesn't like my > "1.7.0_03-icedtea-mockbuild_2012_06_13_11_56-b00" - the current version of > Java on my Fedora16 box, but... think how much fun I could have with this > little project :-). > > Anyway, I thought I would just announce my intentions to play with this on > the list, in case anyone else was interested or already doing so and > fancied collaborating.... or, maybe someone will be able to tell me why it > will never work and save me the effort :-) > > all the best, > > > Jules > > > -- You received this message because you are subscribed to the Google Groups "Clojure" group.
