Hello to everyone.
There is the possibility of limiting the use of the cores of the CPU, for example, use 3 cores in a quad-core for einstein@home? Without using the resource share that does not work..
thanks :)

thanks... and if i want to use 3 cores with einstein and one core with another project? :)

Then set your resource share to 75% to Einstein and 25% to the other project ;-)

i've try, but it doesn't work...boinc always downloads tasks for eistein...and elaborate only einstein wus...:(

Boinc is probably paying Debt back to Einstein, in time it should equalise, then it should work,

Claggy

Nah, he should be right about this. Ressource share is set for each project individually (and in each profile, to be precise). And it tells BOINC just what one would expect, in this case "dedicate 75% of my computing time to Einstein and 25% to the other one. If you can."

Note that this doesn't mean you're getting a 3:1 RAC ratio, as this depends on the projects themselves.

the project is test4theory of CERN, that has a very long deadline, so i have to find a way to elaborate wu from t4t and wu from einstein at the same time...:)

Claggy, I've seen you be a reliable source time after time, but I think this is an error.

Resource share appears as part of "computing preferences" which in the Einstein page set says right at the top of the page "These apply to all BOINC projects in which you participate."

On the SETI version of this page, an additional line adds the observation "On computers participating in multiple projects, the most recently modified preferences will be used."

Now, on the other hand, if you are using app_info to run simultaneous tasks on a GPU, nothing tops you from running 3-fold Einstein and 1-fold SETI, but that is another matter not involving the computing preference mechanism.

As ExtraTerrestrial Apes has already pointed out, resource share is part of the Project Preferences, Not Computing Preferences,
changing selections on the Setiathome Project Preferences will have no direct effect on the Einstein Project Preferences,
(deselecting Use CPU or Use Nvidia GPU at Setiathome or only having Astropulse v505 selected will have an indirect effect of getting more Einstein work)

First of all i'd upgrade Boinc to 6.12.34 or later as Upgrade BOINC client to version >= 6.12.34 asked,

The latest development build is 6.12.43, a lot of the fixes have been just for that project:

i've try a few days ago, but the situation doesn't change (and in this version there isn't the message page...it's hide...)

If you want to keep the old style Boinc Manager, copy boincmgr.exe and boinc.dll to a safe location, and once Boinc 6.12.x is installed, copy them back, eithier over-writing the 6.12.x Boinc Manager, or giving it a slightly different name,
(i've actully got both 6.10.58 & 6.12.43 Boinc Managers on my Laptop, and just fire up whichever Manager i want to use)

So what is the Debt to Einstein? If you make a cc_config.xml file with Notepad with the following in it:

<cc_config>
<log_flags>
<debt_debug>1</debt_debug>
</log_flags>
</cc_config>

Then drop the file in your Boinc Data directory, (It'll be hidden, the location is in your Boinc Startup messages), now do a Read config file, you should get lines saying:

18/12/2011 15:50:37 Re-reading cc_config.xml
18/12/2011 15:50:37 Re-read config file
18/12/2011 15:50:37 log flags: file_xfer, sched_ops, task, debt_debug,

Now just copy and paste one cycle of the debt messages, one you're done that, edit your cc_config.xml and change the 1 to a 0, then do a Reread config file. (that'll turn the debt messages off again)

any ideas? an app_info or cc_config? :)

AFAIK, no matter what settings you choose, BOINC will be allways using the cores in a dynamic way and it will be hard to achieve an exact 3:1 (or whatever ratio)

If you really want to have always one core crunching for a specific project, then the only way is to have 2 instances of BOINC running in the same computer and setting one of those instances to use only 1 core and attached only to the intended project, while the other instance will be running the other cores and the other projects...
I know that its possible to install 2 BOINC clients, but there is some trick as you need to move/copy the folders manually or else the installer will "upgrade" the previous installation and you will need to change the cc_configs to exclude certain GPU/CPUs so they dont clash... Ive never tried so I cant be more specific, but Im sure somebody else can guide you to get the 2nd instance installed if you want to try...

However, in your case there is a second option, as you have Win7 you can get the virtual PC from MS and use the WinXPmode virtual machine (its free for download for win7 pro and above versions and includes the license to use the XP) and then you will be able to install the second BOINC instance in the virtual XP. As the MS virtual machine only uses one core it will be what you wanted, just keep in mind that under the Virtual XP guest you wont get any usable GPU (off course they will be still available in the "real" Win7 host) also you should install another antivirus for the virtual machine...

Im not sure if all this hassle is worth just to assure a 3:1 ratio, but...

You can set the same preference individually for each machine in the local preferences. So the setting appears only at that particular machine. And it works. I use it for myself.

Thanks for useful information. I plan to use multithreading CPU.
