[R] SMP, Single System Image clustering, multithreading

Hi All,

  I have looked through the following thread:


  and would like to ask after 1.5 year the same question:

  Are there any plans to involve multithread   computations in R?

Few word about my motivation:

  I use R on my OpenSSI cluster with 7 CPUs, so one   could simply think of this cluster as of single computer   with 7 CPU. My own C++ maths run good in parallel   on the cluster. What is even better for me: my C++ code   has *no* any statements about parallelization.   All parallezation is done at command line. When I   start a new piece of calculation from command line,   the process is migrated to a free cluster node   automatically, it migrates even during the calculation.

  The whole project is calculated nearly up to 7 time   quicker then on a single CPU. Thus, I do see the boost   clearly.

  However the same approach applied to R will force me   to use batch mode instead of nice interactive mode.

  Now I am writing this mail and R is still busy with   stats in usual interactive mode. Other 6 processors   are idling unfortunately. It would be really nice   to change this situation.

my best regards,
