[R] simultaneous computing

[Markus Schmidberger]

Hello,

which possibilities are available in R for simultaneous or parallel 
computing?
I only could find biopara 
(http://cran.r-project.org/src/contrib/Descriptions/biopara.html)

Are there other possibilities?
Are there special groups working on simultaneous computing with R?

Thanks
Markus
