Running more than one project on a machine?

[aphex]

Is this reccomended?

I currenly have a few rigs runnin UD Cancer Research and nothing else. Should i put another project on them as well? Or is it best to keep all the power goin towards one..?

If both clients are set to the same priority (idle) then each should get half the idle cycles in theory. It's up to you whether you'd want to focus your efforts on one or spread them out. I don't really see a problem with it.

In theory, that should work. It depends on if you want to help out with more than one project. Since you have multiple systems, my advice would be to keep some on UD, while moving one (or however many you want) over to the other project of your choice.

Running two different projects on the same system means that they're not just competing for CPU time, but also for FSB bandwidth (this would be a problem if you plan to run SETI and something else), and space in the processor cache. Because of these factors, it may be better just to dedicate each rig to one project.

Now, I don't intend to discourage anyone with only one system from running multiple projects if they wish. In that case, the advantage of being able to help in more than one place most likely outweighs the small inefficiency that would result from running two projects. 🙂

It would probably be also very dependant on what you wanted to run with what.

If you've got a hyper threading machine you may want to combine projects that use different execution units.

Any opinion on a project that would work well with UD?

I think there is one project that is based on time, so if you put that on low priority and the other on normal priority then you'll get optimal credit for both.

When running Seti and UD on a single cpu system Seti takes everything.. Even when the priority is set to High for UD..
But when you have a multi cpu system it doesn't matter what you use..
I never worked with hyper threading, but I don't think that there are projects that work well together.. Most projects use
the FPU on the cpu so they still have to share..
You'd have to test to know what works with what.. Good luck!

I would suggest just dedicating certain machines to certain projects, but IIRC RC5 and UD run fairly well in tandem. SETI doesn't play nice with anything else, unfortunately.

Well, different projects has different priorities, even all seems to be running as "idle".
Seti@home-cmd is running at 4, Folding3/genome2 is configurable to 4 or less, "classic" genome is 4, UD is running at 1 (was atleast last time I tried...)

2 projects with the same priority will share equal, while lower priority-projects will typically get less than 1 %.
So seti works great with folding/genome. 🙂

The Folding@home3/genome@home2-client can also be configured to only use max% of the cpu-power. If you for example puts 50% here, the client will never use more than 50% of the cpu-resources. If nothing else eats up the rest, the idle-process gets the other 50%... 😉 Alongside seti, I guess seti will get 75% in this case...
