[R-sig-hpc] multicore mclapply hangs

[Markus Schmidberger]

Dear Rune,

I am using Ubuntu 9.04, R 2.9.1 and multicore 0.1-4.
This combination is working great. Try to use the new multicore release: 
http://www.rforge.net/multicore/

If this is not working, please provide some example code!

Best
Markus
