R-helpers: I'm curious what support R has for parallel writes to a binary file? If I want to use snow to have each node write different "rows" of a flat binary file (possibly out of sequence), are there any tricks/issues I should be aware of?
This is a very hard task, since you have to synchonice the nodes. Typically it is more advisable to collect the rows by the master and write the whole file from there.
