Possible to fold on two cores?

post #1 of 11
Thread Starter 
Alright, I am trying to run F@H on two cores in a linux SMP, however, I can't seem to find out how, because I can't run two at the same time without the second one giving errors.

Any help would be cool,

Do you have a quad core?

If your running the SMP on a dual core CPU, you only need to run one instance. The only reason you run 2x instances of the SMP client is when you have a Quad. Which the new Beta SMP release uses all four cores per one instance...

Seeing the rig in your specs I'm guessing you meant you want to run SMP... Well from what I found, sadly you don't seem to be able to run SMP on a 32bit OS. IF you want to run two normal clients, then you have to remember to change the machine number in the client config file.

It would not be the computer in my specs, however it is on my system.

Sadly, it is only a dual core, so I guess it can't be done anyway. Oh well.

1 Instance of SMP will use up to 4 cores.

If you don't have a quad, 1 instance will use the 2 cores.

You can also run 2 instances of SMP if you have a quad.

It can be done?
One instance of the SMP client will fully utilize both cores.

Well, though I got it running again (had to update Mandriva, online update didn't work). The process of completing checkpoints seems really, really, slow.

Where as a 2500000 step file, used to take two hours, it now takes an entire day.

Could anyone help me with that?

I am wondering if some how the config file was erased and the assembly option was some how turned off.

Maybe not, but that was my idea.

The reason it is taking so long is because the WU is probably worth 1760 points. The WUs you were putting out before were probably under 100 points each.
