Is there any way to fun a BOINC project and another DC project on the same machine? I would like to run folding@home or google compute in addition to my boinc projects especially since LHC and Predictor have been down forever. My BOINC projects take up 100% of the CPU and the other (folding/google) get 0-1% of the CPU even though they are all running at low priority. Seems like it should balance b/t the different processes. Any help would be greatly appreciated. Thanks

The simple answer, as opposed to the technical one, is that BOINC is designed as a way of joining in several DC projects on the same machine. Unless you have an HT processor you cannot run them simultaneously, but you can have them sharing by each taking an hour or so in turn. It's true that the choice of projects is limited at the moment, but that is because BOINC is new and a number of projects are just in the process of getting going in BOINC, with the inevitable teething troubles (but all DC projects have those). You can see the list <a href="http://boinc.berkeley.edu/">here</a>.

It's largely because you can't otherwise have several DC projects existing together satisfactorily that BOINC was developed.

Every DC project has it's own method of detecting if it can run.

When I tried to run CPDN BOINC and classic on the same machine the classic experiment wouldn't start up if BOINC was already running. When I suspended the BOINC version the classic version kicked into life and the 2 programs got a 50% share of processing power when I re-enabled BOINC (but do bear in mind that this was done on a P4 HT running 2 BOINC models, so may not apply in your case).

The other way to share processing would be to use your general preferences to restrict the time period that BOINC is allowed to schedule projects in.

But I have heard that the F@H team are working on a BOINC enabled client ;)

John
This is from 'Google compute' FAQ (about, Q/A 12)

12. I already run a distributed computing program. How will this affect it?

Depending on the distributed computing programs you are running, Google Compute will either share the idle time with them or allow them to use all of the idle time. If you are running the Folding@home stand-alone client in normal mode, the two will end up sharing. If the stand-alone client is in "Higher priority" mode it will end up getting all of the processor when the two are run simultaneously.

Google Compute also works successfully alongside SETI@home. When the SETI@home screensaver is active it will use all of the idle processor time, as it runs at a higher priority than Google Compute. At times when the screensaver is not active Google Compute will work as normal.

Some constantly running distributed computing programs will utilize all of the processor, leaving Google Compute with little or no processor time. This is probably the case if Google Compute stays at 0% complete for a long time. In these cases it is preferable to choose either one program or the other to be run exclusively.
