Presenting Renjin's JIT Loop Compiler at RIOT 2016 [video]

Although I wasn’t able to make it to UseR! this year, I was able to join many participants at RIOT 2016, the “R Implementation, Optimization and Tooling Workshop”.

Like last year, there was a great opportunity to hear war stories from those working up close and personal with the internals of R implementations.

I gave a presentation on Renjin’s JIT Loop Compiler, which is intended to compile loops and other repeatedly-executed portions of R code into extremly efficient machine code upon execution. It’s still not quite ready for prime time, but with the latest release of Renjin, it’s now merged into master, but still behind a flag.

You can turn it on via the command line with the --compile-loops flag, or with the -Drenjin.compile.loops=true system property if you’re running Renjin in an embedded context.

Here’s a recording of the talk I gave (PDF) :

 

Thanks to everyone for great presentations, great questions, and lots of ideas!
