F@H - *Urgent* Quad Cores

When running the console version of F@H on Intel Quad Core CPUs does running say 4 (or 2 or 3) instances of the console (in different folders obviously) make use of a different core on the CPU, because I've managed to borrow 10x Quad cores for a while, I cannot install the SMP version due to rights but can run the stand alone console version...

I thought that to make use of the different cores on the CPU, you had to use the SMP version, but it got me confused when I ran 1 console, it was using 25%, of the CPU (in task manager) then when I ran a second, it was using another 25% on that FAH core and then another 25% for a 3rd FAH core...

My question is, is this actually making use of the other cores, or is it making each core run slower than if I was just running one instance of it?

Any help on this would be appreciated...

btw, currently I've only tested running multiple instances on 1 of the 9 Quad Cores, should see a big boost for OcUK if it makes a difference...
 
As long as you make sure that each instance uses a different Machine ID, they should occupy the cores just fine and give you almost 4x the output of a single core.
 
Yep.

I ran 4 standard clients on one of my quads for a while and it worked fine.

Nice bit of borging there, let's hope you get to keep them for a while :cool:
 
You've only got to look at Task Manager to see how the cores are being used. But you'll still only be getting at most two thirds the PPD from four console clients that you'd get by running one WinSMP client on each PC. And even that's only three quarters of what a quad core is capable of.

Thanks for responses, I've ran another 3 instances on all the Quad Cores and set the machines IDs - seems to be working great. Also running another instance on all the dual cores, hopefully should have these for another 2-3 weeks.

Can you elaborate on why you cant run SMP?

I could and would have if I had more time - a friend was going to help me write a script to deploy them for every machine on the network, but he's been busy/ill, and the way I have to run F@H on them now, is very tedious so I've stuck to running the stand-alone .exe, last time I ran the SMP version, It was a lot more work configuring it IIRC.
 
Just out of curiosity, what name are you folding under? It would be interesting to keep an eye on how much you get fold this week :)
