Multi-Core CPU... Multiple or single folding

post #1 of 5
Thread Starter 
Hi Guys

Sorry if this seems like a noob question. But its never really explained properly anywhere... or not that I can find.

I have a Dual Core CPU and I'm running a 32-bit version of Linux, so I can't use SMP. But I can run multiple instances of the folding client and just assign a client to each core. But is it faster doing two instances at the same time or doing on instance?

I'm currently using two instances and it seems slower than doing one instance. Could someone please shed some light on this please?

Thanks

When I try run SMP, it detects that I'm running a 32bit OS and won't continue

It does take longer to run 2 instances, to finish a single percentage. But the overall, when you combine the 2 instances vs. the single instance is faster. I will give you an example. Lets say it takes me 11 minutes per percentage running single, and it takes 15 minutes per percentage with the dual. If you do the math on this, you can see that the dual instances will be done with 2 w/u's faster than the single instance ran twice. This is just a rough outline. It would take the single instance 22 minutes per percentage, to complete 2 w/u's, while the dual, will get it done in 15 minutes. So the dual instance has better performance in the long run.
