Folks:

We finally have an early version of our parallel processing algorithms
designed for use with raster files to try out on r-forge (along with some
other functions that may be helpful).  We're trying to get some help doing
a shakedown of the code and find any bugs or bottlenecks.

You can grab the code from:
https://r-forge.r-project.org/R/?group_id=1492

[For Mac users, which I am one of, r-forge doesn't seem to build the
installer correctly, but the .tar.gz source file can be downloaded and
installed on a Mac with no problems].

The function we are most interested in getting users working with is
"calc_hpc", which works with a snowfall cluster and includes (when
available) parallel and non-sequential writes to the output file.
 ?calc_hpc has a simple test case to look at if you plan on designing your
own function.

Let us know how it goes and if you have any suggestions!  Cheers!
