[R] How is R working in multicore and multiprocessor environment?

[Hesen Peng]

My Dear R buddies,

I'm feeling ashamed that I've been running my R program on some
servers for a while but do not know exactly how R is working. The
servers are chained together using Sun Grid Engine. Each node has 8
quad-core CPUs. I wonder how many cores and CPUs are used by a simple
single-thread R program. Thanks a lot.

Best wishes,
