Functions like mclapply() work on, say a quad core machine, by setting up new invocations of R to run on each of the four CPU cores. What you have in mind would mean having R run on each of the GPU cores. This is not possible, for a variety of reasons (R needs a terminal shell, it needs I/O etc.). To have R take advantage of GPUs, one must write C/C++ (or FORTRAN) code. Currently packages that do this are very limited. See the relevant CRAN Task View, at http://cran.r-project.org/web/views/HighPerformanceComputing.html You might also take a look at my Rth package, at http://heather.cs.ucdavis.edu/~matloff/rth.html Norm Matloff ______________________________________________ R-devel@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-devel
