If you set things up right, you shouldn't have been using a full core/thread in PrimeGrid. Most likely you were running a CPU work unit instead. When attaching, it is common to pull down a CPU work unit before your preferences are honored. Yes, I have seen it happen many times there. I would recommend looking at the actual work unit name for it to say (ATI) somewhere on it. The only one for ATI over there is Proth Prime Sieve. That might have been what happened at Milkyway as well, but I don't have any GPU on that project.
----------------------------------------Surveil is another non-CPU intensive project like WUProp and Quake Catcher Network (QCN) if you are looking for maxing your BOINC usefulness. Surveil will use a little bit more bandwidth though if you are on a limited service. Edit: FreeHAL has both CPU intensive and non-CPU intensive work that you can use (however it isn't technically a true non-intensive project).

I don't know the difference between a CC or Core Client and the Boinc manager.
But I think since both Boinc managers(?) were running the same tasks, as I mentioned, that it sounds like two managers were running. Do I have that right? Heck if I know. This stuff is confusing. If World Community Grid has any desire for normal folk to use their GPU's in the future then the outlook is dim. Because I'm a computer nerd to some degree. I can repair computers and software conflicts. I also built this computer from scratch from parts I bought off the shelf. This one is an i7 x64 Water Cooled machine. Then if I cannot understand all this stuff about setting up the GPU tasks I really think there is little hope for non nerds. If there is a way for me to pick and choose which MilkyWay@home tasks are ATI, sorry, I don't see that option. I only see the option to join a list of projects or not and then the many preferences. But none say pick this ATI GPU task. Since these tasks run for a couple hours I would have to constantly be picking tons of tasks? I look at all the projects to run out there and since my wife had cancer, so did my dad, my mom, my sister etc that I like running projects that might find a cure for that terrible disease as well as the other humanitarian projects along those lines that WCGrid has running. Trying to maximize my effort with a GPU running would be a cherry on top. I hope we are all learning from this thread, especially myself. Thanks all, |

But none say pick this ATI GPU task. Since these tasks run for a couple hours I would have to constantly be picking tons of tasks? World Community Grid is counted as a single "project", and you can join multiple other "projects" through the drop-down-list in the BOINC Manager. Just like WCG has multiple "sub-projects", like HCC, HFCC, CEP2 and so on, some of the non-WCG-"projects" also includes multiple "sub-projects". The selection of these specific "sub-projects" is done on each "projects" web-pages, similar to how you here at WCG can choose to run only some of WCG's "sub-projects". On GPU-projects web-pages, among the "project specific preferences", also called "preferences for this project (project-name)", you can enable and disable GPU-crunching and CPU-crunching for this GPU-project, similarly to how you can enable/disable crunching of beta-work here at WCG. Since you'll want to use CPU here at WCG and only GPU's on other projects, make sure you de-select the "Use CPU"-option. If you joins multiple GPU-projects, you'll need to do this configuring on each of the GPU-projects.  "I make so many mistakes. But then just think of all the mistakes I don't make, although I might." |

Nevada Bob...I was in no way suggesting for you to pick and choose work units from the BOINC manager. As a "computer nerd" you will find it rather easy to log into the account of whichever project you want to support and choose your preferences from there. You will find that on the projects web pages they do give you options such as whether to use GPU, CPU, or both. You can also set up profiles with each of the projects so that if you want one machine to only crunch GPU and not CPU, you can while other machines can do cpu only or both. Again, this would require you to go to their web page and log into your account there...not the BOINC GUI. If this is too much for your liking, then yes it is asking a bit much. However, once WCG has GPU work...it shouldn't be too much of a hassle for this option.

Eliminating all the stuff about other projects as that is beyond what will happen when WCG releases a GPU project. Their goal (and probably the reason it isn't live yet) is to make this process as simple as possible. It will run on the current client version and will be easily configurable through your preferences settings. If these two goals are not met, you won't see it on WCG.

you can enable and disable GPU-crunching and CPU-crunching for this GPU-project, similarly to how you can enable/disable crunching of beta-work here at WCG. Since you'll want to use CPU here at WCG and only GPU's on other projects, make sure you de-select the "Use CPU"-option. Forgive me for quoting myself. But: I configured the preferences both for MilkyWay and then in the Home setting for the computer. I unchecked the box for NVidia and CPU and updated the project. It still is using one of my CPU threads up. Even though I went to the MilkyWay website and unselected use CPU. It still used the CPU. Even after multiple times I told it to update the MilkyWay Project. You will find that on the projects web pages they do give you options such as whether to use GPU, CPU, or both. You can also set up profiles with each of the projects so that if you want one machine to only crunch GPU and not CPU, I tried that. It didn't work. It still used the CPU. Look, I don't want to frustrate you guys. I know your trying to be helpful as we all could be doing something else with our time. We want to help and we wish to be altruistic, helping others and the world be a better place. I have tried de-selecting CPU. Setting up the profiles on the respective websites. It still uses up one of my CPU cores. All these suggestions have not worked for me. If they haven't worked for me then others will get frustrated and quit trying as well. That is not what we want. We want a smooth and simple process that works. I'm just letting you know that it's not working for me. Your input is appreciated and gratefully received. |

Now when you say it uses up one of your cores, are you meaning 100% or a partial core? I ask this because all of the GPU projects will use a small portion of a thread unless it is OpenCL which will use the majority or a large chunk of a thread. I am specifically mentioning threads because there is a difference and should not be confused. For example: Cullen/Woodall Sieve work units from PrimeGrid use about .02 CPU thread to manage the GPU (nVidia) but GPUGrid uses .26 CPU thread. However, I still have all eight threads also crunching WCG projects at the same time. I have not ran Milkyway on a GPU, so again can't tell you their habits but with PrimeGrid it should be the same as mine. I have one ATI card that does their Proth Prime Sieve and it behaves in this manner.

I don't know the percentage of a core that it uses. Just the result. Which of course you know is the loss of one core to WCGrid. Not my desire. I know that by using 7 out of 8 cores that this does not leave one core doing nothing. It just reduces the entire percentage of work spread out over all 8 cores. So, I was hoping that if the GPU project needed a partial core it would not bump one of the WCGrid tasks. Just like me using OpenOffice, Firefox, Thunderbird, and other software on my machine does not bump out a core for WCGrid. Unfortunately it did.

In the BOINC client under the status header it will tell you it is using X CPU + 1 GPU. That is how you can tell basically what percent it will use. You are correct that if you have BOINC set to use 100% of processors, it should use all 8 threads. However if you are specifically limiting it to 7, it should still use 7 WCG tasks + 1 GPU (unless you are like me and have multiple GPU's in your system). If it isn't, then you are either crunching the CPU version of the work unit instead of GPU or have something misconfigured. Could you post a copy of your first 25 or so lines in the event log?

Excellent idea! I think the clue you are looking for is this line:
