[R] SMP, Single System Image clustering, multithreading

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
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,
