At least on linux, CRAN builds using openMP. I got a valgrind report once [shame on me btw] showing that 9 (out of 10) threads were running examples.
So my best guess is that it will do the same for Windows since it also has openMP support according to WRE[1]. I wouldn't know why not, except for the reasons Dirk already mentioned. It will not do this for OS X since WRE states clearly that OS X nowadays uses clang, and the Apple builds currently have no OpenMP support. so if nobody has openMP support on OS X, for sure CRAN doesn't have it. /M [1]https://cran.r-project.org/doc/manuals/R-exts.html#OpenMP-support Op ma 24 aug. 2015 om 19:04 schreef Joshua N Pritikin <jpriti...@pobox.com>: > On Mon, Aug 24, 2015 at 09:57:05AM -0700, Zhian Kamvar wrote: > > The way several packages have implemented OpenMP is to wrap it in > > pre-compiler statements i.e.: > > > > // Include openMP if the compiler supports it > > #ifdef _OPENMP > > #include <omp.h> > > #endif > > > > This way, all compilers can build the code and those that have OpenMP > > (even modified versions of clang: https://clang-omp.github.io/) can do > > so in a parallel fashion. > > Yes, of course, but you're missing the point of my enquiry.
