Parallel loop

Thanks for the feedback. Part of my problem is that I need the most recent copy of R. My IS team told me they can only get an earlier copy using apt-get, but I think there must be a way so I've tasked them with figuring it out. My OS is Kubuntu. I just thought it odd that it could only detect the number of CPUs rather than the number of cores. I'm completely new to parallel processing but it seems that something is not right in the core detection. One quetion I still have regrds child processes. I understand they finish on their own, but what if I need to kill those processing because of an obvious problem. How can I do that?
If you kill the parent, then all of the children should die. On Ubuntu, r-base and r-base-dev are the packages; see http://cran.r-project.org/bin/linux/ubuntu/README You don't need the most recent. Just 2.14.0 or higher.
