Thank you Gabor,I am currently evaluating my options, being bound to Win and not having admin privileges on the Server... it is a pain.
Running multiple igraph functions at the same time is exactly what I want.and I guess I have to rewrite some of my functions to fit lapply and similar functions, I have been using too many loops. But I am getting into troubles when I do something like lapply(graph,function), I guess because of coercing graphs into lists...
Anyway, I will report about how I go. thanks Martin On 8/31/2010 11:48 AM, Gábor Csárdi wrote:
Martin, I used snow with an MPI backend (LAM), and it works fine. It is also very easy to use, on a multicore machine or on a cluster. This will not make igraph functions faster, of course, but you can run more functions at the same time.

I see that multicore will not run on Win, did anyone play around with foreach, or mapReduceR or others?
