The "title" says it all. I am new to BOINC.

I want to run 2 projects at the same time: 1 using the cpu and a different one using the GPU.

My question: How would I configure my machine to do so?

I previously clicked "Add Project" while viewing the BOINC Manager. While doing so did add another project, it appeared that I could only run 1 project at a time.

I want to run both at the same time.

I appreciate your insight.

Thank you.


FYI:

64 bit Linux
Nvidia GTS 250
4 gb ddr3 ram

At first, perhaps just take a look at this info: http://boinc.berkeley.edu/wiki/preferences

You need to login to _your account_ page on each project site and visit the "preferences for this project" page. For example http://einstein.phys.uwm.edu/prefs.php?subset=project

There you can choose what applications you want those projects to run and whether you want that project to use cpu, gpu or not.

It helps to make good decisions if you visited also the _applications_ page of each project. There you can see what type of work (cpu, cuda for nividia gpu..) each application is offering. For example http://einstein.phys.uwm.edu/apps.php

Then you just need to setup cpu only for one project and nvidia gpu for another. GPU will use some cpu also... so it is normal when you see that happening. You need to double-check the application you setup for nvidia gpu really has work for nvidia gpu. Otherwise that project will not be doing anything.

You can find those links always on the home page of each project.

On your computer itself, you need to check boinc manager... tools... computing preferences... and make sure it is allowed to use also gpu.

So, would I need to have multiple "BOINC" managers running, or would I only need one instance running?

It sounds like you are saying I would only need one instance running for all BOINC but I would use individual project pages to handle individual project details.

Is that a fair summary?

Thank you again!

It sounds like you are saying I would only need one instance running for all BOINC but I would use individual project pages to handle individual project details.

Yes, only one boinc manager instance is needed. That is exactly the way to go.

You can control the individual project settings (applications etc.) thru individual project pages. Maybe there is also some other way, but I think the easiest way is via those web pages.

To change the general settings the easiest way is to do it "locally" via boinc manager. Those settings have an effect on all projects you are running.

(If you for some reason would like to use web pages to mess up with all settings, general settings for all projects can be controlled also thru individual project pages. There is a section for general settings on every project site also. For example http://einstein.phys.uwm.edu/prefs.php?subset=global

When boinc manager is connected to internet, it checks if the general settings have been modified somewhere. It doesn't matter which project site you use to change them. The last changes will always apply, where ever you made them.)

Under the "computing preferences" section of each project website, you will find options that allow you to specify whether a specific project can use your CPU or GPU; some projects have apps for both and will use both unless you tell them otherwise.

If you're into customization, there are a lot of things you can do with the BOINC settings, and by tweaking various config files beyond that. If you are looking for an easy way to manage multiple projects (instead of visiting the webpage for each one) then there are account managers that handle that side of things for you.
