Boinc multiple gpu12/11/2023 ![]() It only appears to run a single task at a time but, it doesn't give Computation Errors anymore though. was the only one giving me fits, and the only one that I tuned using the app_config with the settings but, I think I could probably tune it slightly differently, as I have the GeForce GTX 690, which is a dual-GPU card, and was causing the cuda_fermi to have fits before the tuning. I'm running GPUGRID, MilkyWay, and World Community Grid. In a rich man's house there is no place to spit but his face.Īfter a lot of hair pulling, and article searching - I followed the example below, and got my system working also but, am wondering if I should retune for the settings for my system? Could someone please advise me on what might be good settings to use? ![]() The max_concurrent line is (in practice) optional - I'd leave it out completely when using app_config.xml for this purpose.ġ) That the file is properly named app_config.xml, and hasn't been turned into app_ by your editor.Ģ) That you've put it correctly in the project skildude - I refer you to Looks good to me - I'll try and figure out what went wrong - any clues in the Eventlog?Įdit: you're missing 0.02 - maybe it needs that tag as well.Įdit 2: with a max_concurrent of 4 you are limiting to 2 tasks on GPU plus 2 tasks on CPU (provided enough GPU work else more CPU tasks can run), is that what you want? That's quite a bit easier than trying to create app_info.xml from scratch for stock + x41zc. Logically anything running on a computer needs CPU time, but some projects may have negligible or unreported usage.Skildude, Alex2 knows exactly what he's trying to do and that is an app_config.xml file to run more than one instance of _stock_ as the Lunatics installer is unavailable. works for me, configuring didn't yield positive results in later versions of BOINC and/or on AMD GPUs.) But this will only really work if you have a GPU running WUs from a project that can be configured this way. So while I don't think that you can run more WUs than CPU cores, I recommend maximizing your GPU-based WU progress by playing around with the number of WUs assigned to each GPU. Assigning too many WUs simultaneously to a GPU can have huge negative performance impacts, so 2 WUs is what's recommended. Also note that I've used the application preferences located on the project's web page (or locally in the \Program Data\BOINC\projects\app_config.xml file, which needs to be created if you don't have one) to allow two WUs to run on 1 physical Nvidia GPU, while a single WU runs on the integrated Intel GPU. The bottom list is an example of what mixed WUs running in a multi-GPU environment looks like and, even on a 4-core/8-thread CPU I get a reported usage of "0.00598 CPUs" for one project's work unit while being processed by the GPU. It doesn't need a lot of time on the core because it's a primarily GPU-intensive WU. Either that, or it really is 0.168 of a core in terms of time allotted to processing that task. However it also shows "0.168 CPUs" assigned, which I assume corresponds to 1 of my physical cores (I'm running a 6-core/12-thread CPU) since 16.8% is roughly 1/6th. In the top list you can see that I have three WUs runing, one of which has 1 AMD/ATI GPU assigned to the WU. ![]() Here's an example of two of my PCs running mixed work units: So no, you probably will not have a situation where you can configure the BOINC client to run a mixed group of work units and have a number of units running greater than your number of logical cores. The short answer is that every task need some amount of CPU in order to run. ![]() If your devices are running hot, and you can't add cooling, you can reduce heat by limiting the amount of CPU BOINC is permitted to use.ĭoes this sidebar need an addition or correction?

Be smart with your electronics, never operate them with inadequate ventilation. Users can decide which projects they participate in, using the free and open-source BOINC client software.
