Why don't you start at http://wiki.r-project.org ?  It's after all a wiki for
the R community.

I see no problem at all. The HPC/R/MPI aspects should be cross-distro, and
even the Debian/Ubuntu aspects may have some bearing on other distros if and
when they use the same library patches.

Yes, wasn't that the point of (r)sprng ?
