?multicore perhaps

Hello all,
I upgraded my R workstation, and to my dismay, only one core appears to
be used during intensive computation of a bioconductor function.
What I have now is two dual-core Xeon 5160 CPUs and 10 GB RAM. When I
fully load it, top reports about 25% user, 75% idle and 0.98 short-term
load.
The archives gave nothing helpful besides mention of snow. I thought of
posting to HPC, but this system is fairly modest WRT processing power.
Any pointers of where to start?
