Hi Gianni
Depending on the computer your using it can make sense do do things in
parallel. If you have a single core chip it is not very useful to run
multiple tasks at the same time, for multi core chips it is.
There are a lot of possible ways to do that see:
http://cran.r-project.org/web/views/HighPerformanceComputing.html
I myself run sge (sun grid engine) on my own computer (ubuntu) and use
the Rsge package to interface with it. This is mainly useful for me
since it allows easy scaling up to cluster computers using sge. If your
not planing that sge is maybe not the most sensible option.
There is also a r-sig-hpc list that deals with high performance issues
maybe it is worth going through the archive.

Dear Researchers,
i am analyzing statistics of several grids image (i.e. 3 patch: A1, A2, A3)
for my work with 4 resolution scale (0.5,1.0,1.5,2.0). This take a lot of
time. I am asking about reference and web link to learn how I can run in the
same time the same loop for the patch A1, A2 and A3. I open in the same time
three windows of R but It's not elegant.
Thanks in advance
Gianni
