He said 'pc' in the part you excised, but failed to follow the posting guide and tell us his OS. I am guessing this means Windows, on which multicore does not run.

There are several other solutions on CRAN: I'd suggest 'snow' which can run over sockets on a single Windows machine, and also (with a lot more difficulty) via Rmpi.

 I'd recommend the "mclapply" function in the "multicore" package.  The only 
drawback is that you can't run your code in a GUI any more.
