Dual core question

post #1 of 14
Thread Starter 
Hey, I just started my first WU for you guys (ill make sure to check in when its been completed and sent ) and I am running a P4d. Now from the FAQs I read before starting today, I read up on how to enable both the cores.

My understanding of the answers here already was that this program would use 100% of 1 of the 2 cores. I was wrong and suprinsingly I saw that both cores were running in tandem with each other. It is always 70/30 60/40/30/70 40/60 and so on.

The FAQs also talk about the dual core limiting one process to 50% capacity, therefore you could do exactly the same process again and not notice any performance loss on either Fold. But the load is split between the two cores, so if I ran another Fold, wouldnt this lower general performance for each fold?

Basically, why does it chooses to use a proportion of capacity from both cores, rather than stick to one core at 100% and the other at idle?
And is there no way to max out a Dual Core processor with one program?

Thanks

Well here we go.

Each Client will Utilize the Free Cycles of the Core its Assigned to. It wont share Both cores unless you set its affinity to 1. In Windows Task manager 100% Means that both cores are Fully Utilized.

By having 2 Clients ( Each on a seperate core ) You will get a gain in points as you will have two seperate clients doing two seperate jobs....Increases productivity.

With my processor, one is idle and the other one is working full load.

Riiiiiiight Thats a good thing, yes?!

So there's the performance bit done, but how come splat00n is running 100/0? Just trying to get a better understanding of the way things work.....

I believe the way it works is that when a program is launched that one core takes over it, leaving the second core free for another task.

What hes doing is letting Folding utilize one whole core and keeping the other one free for general system use.

So just half of what the FAQ instructs for running 2 WU on one dual core processor?

Sounds like sense for that, I'll be waiting for this WU to finish then I'll be starting both cores. Thanks for the quick answers

You have got it...Good luck.

I couldn't get two cores to run yet, or two programs to run.

You need to have 2 Folding at home clients in different Folders .
