R is not multi-threaded and will not be able to automagically make use
of a SMP machine. I'm pretty sure what you want to do is configure
your app to launch 4 R instances and manage of queue of some sort.
The problem is that I work with algorithms that use great
amounts of data (files from 2 to 20 or 30 Mb) so, it will
be great to divide the work of analyzing the data among
all the processors....
Is that possible?
