I have released a new, faster, version of R, which I call pqR (for "pretty quick" R), based on R-2.15.0. Among many other improvements, pqR supports automatic use of multiple cores to perform numerical computations in parallel with other numerical computations, and with the interpretive thread. It also implements a true reference counting scheme to reduce the amount of unnecessary duplication of objects. There are also substantial speed ups in general interpretive overhead, and in particular operations.
Readers of r-devel can try out pqR by downloading a source tarball from radfordneal.github.io/pqR (only tested on Linux/Unix so far). The source repository is github.com/radfordneal/pqR - look in the MODS file to see how the changes from R-2.15.0 are organized. The R Core Team may wish to look at the list of bugs fixed in pqR, in the NEWS file, since many of them are present in their current version of R. I will be making a series of posts discussing pqR at my blog, which is at radfordneal.wordpress.com ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
