Hello Everyone

I have a dual-core Intel i3-370M processor and Windows 64 operating system.
I have a 3GB RAM and my processor can support a maximum of 8GB RAM.

I have virtual memory enabled on my computer.

I am running a program in the 64 bit R which implements a MCMC on a large
dataset and involves around 80000 iterations.

The processor estimates that it will take around 1000 minutes to complete
running the program.

However when I check the CPU usage it shows only 25% usage.

I have read on threads that R runs on only 1 core - and thus was expecting
a CPU usage of around 50%.

It would be great if anyone can point out a way by which I can make the
processor use 50% of the CPU which I believe would allow the program to be
run quicker.

Best
