[R] The snow package

[njmulakk]

I have a few questions regarding the snow package:

1) Is fine-grained parallelism even possible with R/snow?

(ie, one task that spawns sub-tasks to do work, with results sent back to the 
parent task).

The example(s) only seem to be totally-independent processing (which can be 
done just as easily
with shell-script wrappers....)


2) If so, is an example available?


3. If not, then it is still worth messing with snow to see if you can get an R 
program to skip through multiple directories, doing the independent processing 
in each to avoid a potential race condition that could occur if multiple R 
process one with one .RData file.

Thanks a lot!
