Hello, I was taking a look at R code, and there is some places that should be easily parallelized, as the dist() function, for example. Is there an interest on do such thing on R? I would like to start making patches to parallelize, but how comfortable with this are the main developers team on R? Best regards, Michel
Maybe you can use the same approach as the pnmath library which replaces many of the math functions with pthreads enabled ones when it is loaded? That way people have a choice, and those who like to do things like doMC() and therefore want to keep the core R single-threaded can still do so.

We are working on extending the approach in pnmath to other functions. Hopefully this will make it int othe R distribution in some form within the next couple of releases. luke On Mon, 30 Aug 2010, Michel Boaventura wrote:> Hello, > > I was taking a look at R code, and there is some places that should be > easily parallelized, as the dist() function, for example. > > Is there an interest on do such thing on R?

Is there a place where I can see how the work is going, and try to help it out? Regards
