[R] Preparing for multi-core CPUs and parallel processing applications

[Dirk Eddelbuettel]

Steve, 

Martin already mentioned r-sig-hpc and the HPC task view for the bulk of your
questions. The Schmidbger et al paper (linked from the Task View) should
address a few of your questions.

Just two more quick add-ons:

Besides the somewhat exploratory package 'gputools' from U Mich (linked from
the Task View), there is no 'R CUDA' yet.

The newest is R 2.9.1, see http://cran.r-project/bin/linux/ubuntu which
explains things in more detail. For more questions, come to the r-sig-debian
list is for Debian and Ubuntu specific questions.  Debian and Ubuntu do have
good support for Rmpi etc.

There are 'special interest group' mailing lists for HPC (see above),
Debian/Ubuntu and for geographic / spatial modelling. 

Hth, Dirk
