From my testing, it seems my PC hasn't gotten a single task from that project since installing that GPU. http://www.gpugrid.net/results.php?hostid=326413

Since max_concurrent documentation has a 'documented meaning' already, you might use that to suggest (gently push) toward keeping it the same, and putting any work fetch max limits into a new variable. I could see it ending up that way maybe.
23) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51266) Posted 11 Jan 2019 by Jacob Klein Post: :) I'm a rock star at breaking things, for sure! I am happy to hear that you find the feature as useful as I do! I about to join you as a "rock star" for breaking things to apparently. The client code commit that DA wrote to fix my original problem is going to cause major problems for anyone using a max_concurrent or project_max_concurrent statement. The unintended consequence of the code change prevents requesting work fetch task replacement until the hosts cache is empty. Only then does the host report all finished work and then asks for work to refill the cache. So the end of keeping your cache topped up at every 5 minute scheduler connection. The PR2918 commit is close to be being accepted into the master branch. I have voiced my displeasure but since only DA usually authorizes pull requests into the master branch, that decision is up to him. Richard Haselgrove also has voiced his concerns. It sounds like you were using "max concurrent" to mean "only run this many at the same time, but allow fetch of more." David is likely arguing that, if you can't run more than that many simultaneously, then why buffer more? Consider tasks that take 300 days to complete (yes, RNA World has them). If you're set to only run 3 as "max concurrent", then why would you want to get a 4th task that would sit there for 300 days? You might consider asking for a separation of functionality --- "max_concurrent_to_schedule" [which is what you want] vs "max_concurrent_to_fetch" [which is what David is changing max_concurrent to mean]. Then you could set the first one to a value, and leave the second one unbound, and get back your desired behavior. I hope this makes sense to you. Please feel free to add the text/info to the PR. Note: I doubt it waits until the cache is completely exhausted of max_blah items before asking more. I'm betting, instead, that work fetch will still top off, even if you have some of that task type, but only up to the max_blah setting.

The basement cruncher, my old XPS 730x, has 4 6-pin connectors, and I previously made 2-more using molex adapters, for a total of 6 6-pin connectors. But 0 8-pin connectors. My GPU additional power requirements are: 6+8 : EVGA GeForce RTX 2080 XC ULTRA GAMING None: EVGA GeForce GTX 1050 Ti SSC GAMING 8+8 : EVGA GeForce GTX 980 Ti FTW GAMING ACX 2.0+ 6+8 : Dell GTX 980 Ti 6+6 : EVGA GeForce GTX 970 FTW ACX 2.0 6+6 : EVGA GeForce GTX 660 Ti FTW+ 3GB w/Backplate 6+6 : MSI GTX 660 Ti TwinFrozr III OC 3GB So, I think this means I'm going to: Area 51 R2: 2080, 980 Ti, 980 Ti XPS 730x: 970, 1050, 660 Ti Shelf: 660 Ti Fun!
25) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51250) Posted 10 Jan 2019 by Jacob Klein Post: :) I'm not too concerned with cooling. My cramped GPUs run hot, and I know it. For my main rig, I just don't do GPU work on it during the day, and instead let it run at night. Even with a max fan curve, it routinely runs around 75-80*C overnight, and the small office becomes very well heated. But I already stress tested the overclocks, and know it is 100% stable, and the GPU fans have proven to be very durable too. What can I say? I like it hot and I like it loud. ;)

27) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51241) Posted 10 Jan 2019 by Jacob Klein Post: Thanks. I confirmed that at least one of the Einstein task types failed immediately on my 2080, so I also added them to my GPU Exclusion list for that GPU. Pity, really.
28) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51233) Posted 10 Jan 2019 by Jacob Klein Post: Why do you have an exclude for Einstein?
29) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51227) Posted 9 Jan 2019 by Jacob Klein Post: :) Did you guys know that I'm responsible for <exclude_gpu> being included in BOINC? I know how it works and how to use it. I didn't know that GPUGrid was giving work to 20-series GPUs, even though it would fail on them. That ends up being good for me, in a way, because I can get GPUGrid work for the other 2 GPUs in the system, and BOINC should get work from other projects for the 2080. Thanks for helping to clarify that for me. I'll definitely be adding the GPU exclusion.
30) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51222) Posted 9 Jan 2019 by Jacob Klein Post: Hmm, I thought that wouldn't work because BOINC reports to the projects the "biggest card", so GPUGrid would think I have 3 2080 GPUs and thus wouldn't give me any work. Are you sure your proposal would work and still allow me to do BOINC work from other projects on the 2080? If so, how?
31) Message boards : Graphics cards (GPUs) : Advice for GPU placement (Message 51217) Posted 9 Jan 2019 by Jacob Klein Post: Hey folks, I bought an RTX 2080 on Amazon, being delivered tomorrow, and was wondering if you might help confirm my plans for my GPUs. I have 7 GPUs worth crunching with: 2080, 1050 Ti, 980 Ti, 980 Ti, 970, 660 Ti, 660 Ti. I have 2 rigs each capable of housing 3 GPUs: - 3-yr-old Alienware Area-51 R2 main gaming rig - 9-yr-old XPS 730x basement cruncher. My goals are, in this order: - Use the 2080 for gaming - Keep a 980 Ti for gaming and testing - Optimize ability to crunch GPU Grid tasks on all GPUs, knowing that 2080 isn't supported and may cause tasks to not be issued on the PC that has it until acemd is updated (right?) - Use the GPUs to crunch other projects if GPUGrid isn't setup yet to support me I'm thinking of doing this: Area-51 R2: - 2080 (for sure staying in this PC) - 980 Ti (for sure staying in this PC) - 660 Ti reasoning: Game on 2080, 980 Ti as backup/testing games, and all 3 crunch BOINC for non-GPU-Grid projects until GPUGrid gets fixed XPS 730x: - 1050 Ti - 980 Ti - 970 * reasoning: Maximum GPUGrid with remaining GPUs Shelf: - 660 Ti - 460 (gets a friend on the shelf) Does this sound like it'd "best optimize" my goals? Let me know. Thanks. * Great deal here, in my opinion - $850, on sale for $50 for $800, and a 5% %40 coupon checkbox, for final total $760 pre-tax, includes 2 games, Battlefield V and Anthem. https://www.amazon.com/gp/product/B07GHVK4KN

33) Message boards : Number crunching : Nvidia Driver 416.34 and above (Message 50979) Posted 29 Nov 2018 by Jacob Klein Post: Have you been active in NVIDIA's GeForce User Forum, in the GeForce Driver Feedback threads? https://forums.geforce.com/default/board/33/ There is a thread for each driver version, and I read them all, and yes I believe that I have heard of some people having similar problems with Release 415 drivers. But I haven't had any problems, personally. Make sure to visit there to post your feedback, and also see if there are any workarounds, tips, or solutions. And if you want to report an issue more thoroughly so NVIDIA has a better chance of fixing it, then you should follow the steps in the first post of a driver feedback thread, to fill out the NVIDIA driver feedback form.
34) Message boards : Number crunching : Nvidia Driver 416.34 and above (Message 50977) Posted 29 Nov 2018 by Jacob Klein Post: I once had a problem where my custom GPU fan curve would get set to "off completely" despite tasks running the temps up to 100*C. When that problem happened, it turned out to be a buggy version of eVGA PrecisionX, that didn't work right when suspending or shutting down and then loading Windows - It stored the very bottom of the curve as a constant setting when resuming from Fast Startup! Ugh. They fixed it eventually, but that was a nasty nasty bug! I have since ditched that software, and use MSI Afterburner, and highly recommend it. I also disabled Fast Startup in Power Options, so my PC won't be susceptible to hibernation/resume problems. I'd advise you to double check your fan monitoring software, as it seems possible that the problem you are having is with that software, instead of the NVIDIA drivers. Make sure to report any results of any more testing you do! Thanks! Kind regards, Jacob Klein
35) Message boards : Graphics cards (GPUs) : CUDA 10 Support Request (Message 50836) Posted 7 Nov 2018 by Jacob Klein Post: I see. I bet most of us are just wanting Turing app support, instead of CUDA 10 support ... And I thank you for pointing out that they are separate. GPUGrid devs: Please update the app! :)
36) Message boards : Graphics cards (GPUs) : CUDA 10 Support Request (Message 50833) Posted 7 Nov 2018 by Jacob Klein Post: Are Turing 20xx GPUS working in this project? I thought the answer was no, and that an app update from the GPUGrid devs was required. Keith do you have such a GPU to test?
37) Message boards : Number crunching : Store at least X days of work v.s. Store up to an additional X days of work (Message 50829) Posted 5 Nov 2018 by Jacob Klein Post: If BOINC has less than "Store at least X days of work" available, for a given resource, then it starts asking projects for work for that resource. When asking a project for work for a given resource, it will ask for enough work that will keep the computer busy not just for that "Store at least X days of work" setting, but additionally for "Store up to an additional X days of work".
