[R] Neural Net and SNOW

Hello R masteRs,

I was wondering if somebody had already implemented a parallel version of the function Nnet (with the SNOW package for instance) and would be willing to share a few pointers on how to achieve it. I have a training set of dimensions 905,000 X 5. Should I just get more RAM and run the nnet on one procesor? Or is there a slick way to parallelize the computations? I have tried to load the training set on each node and have the nnet function run on the master, but it seems that the master node will still put the whole training set in memory....

Thank you in advance for your suggestions,

Ron Piccinini.
