R utilizing 25% of CPU for Dual core i3 370M processor
2 messages · Shantanu MULLICK, Joshua Wiley
You probably have hyper threading so even though you only have two physical cores, there are 4 logical cores, hence 25%. Google can lead you to how to adjust this, if possible. Cheers, Josh

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
Shantanu
