[R] multicore, mclapply memory problem

[Fabrice Tourre]

Dear list,

I am using mclapply(from multicore) to use multiple cores on one
server. If I do not use mclapply, just one core, my R problem will use
4G memory. When I use mclapply and set mc.cores =10, each core will
use 4G memory. So totally it will use 40G memory. Is it possible let
each core to share some memory on the same server?

Thank you.
