When you tune Collatz properly it really works the GPU hard probably more than any other project. It's almost like it needs to get warmed up first. I've only seen that behaviour on my GTX 970's but I imagine there could be a lot of GPU's that have similar problems. Then after it starts crunching properly I wait a further 10 - 15 mins then change it back 29 and then it will works as it should once again. ![]() All I do is reduce the "sieve_size=" down from 29 to 27. Nice!!! Well Dingo: Sometimes when I fire up collatz after not crunching there for a while I start getting constant compute errors. Thanks for help with the much needed changes in the config file. Quote from: NudgeyNR on September 05, 2019, 07:13:03 PMġ9:06 down to 7:22 - a massive difference and no errors yet. Which translates almost exactly to the settings he used in his. If you scroll down the page you'll get to the part we are after. Click on any of his work units in the "task" column. This is the first guy I could find who was not anonymous in the top lists with a 1080 ti like yours. Well you can unless that person hides their devices(in the top computer ranking the host is marked as Anonymous) So if you find someone with a similar GPU than you have that seems to be doing a lot better than you you can try his settings. It's also possible to see the settings others are using by simply looking at their tasks output on the collatz website. If it fails again try lowing those two setting one number lower and try again ect. If it fails with a computation error then try lowering both the lut_size and sieve_size settings by 3 if those settings work then try raising each setting +1 at at time until you have the best setting possible. config file using notepad).Īfter the settings have been inserted and saved click on the "options" menu in boinc manager and click the menu item that says "read config file" then suspend just one task and see how it runs. Then suspend all work and add the new settings to the above mentioned. Plus the extra credit is unbelievable.įirst download some work and then run a few tasks to see what your baseline is. Give it a try it's not as hard as it sounds. Sieve_size= <- same with this setting as with the above. Lut_size= <- Try increasing this number +1 at a time until your times start getting slower or. Sleep=1 <- try this setting with 1 or 0 to see which is best for you.(only needed for Nvidia cards ) If you like you can try a few settings you find in this thread. collatz_sieve_1.30_windows_x86_64_opencl_ati_gpu.configįor Nvidia Cards it's collatz_sieve_1.30_windows_x86_64_opencl_nvidia_gpu.config EG: For AMD cards it's a text file called. The file name will be similar to the GPU app that your using. The settings file can be found in the collatz folder (_collatz) which is can be found in the boinc data directory. It's a large increase over running multiple Wu's. It's possible to increase production close to 2 fold maybe even more depending on the GPU your using. A bit of reading and testing is required to see which setting work best for each GPU you have but it's by far the best way to go. Where did you find the option to check/uncheck the usage of the CPU? I can't see this in the "Computing preferences" page.Hey Nudgey, yea you can and it does help a little but it's much more productive to tune your settings for best results.

Describe the solution you'd like A feature that allows the user to be able to enable " only compute GPU" related tasks. So I would like to have BOINC only be able to compute GPU tasks. Therefore I would like that BOINC uses them for computation, however I don't want that BOINC uses the CPU since I will be using that.

Project of choice Your account Project preferences Correct venue/location Edit preferences Uncheck Use CPU? Check Use NVIDIA/ATI/INTEL GPU? Save preferences Update BOINC on that project Use of hardware is a project preference because not all projects have (all) GPU applications. ![]()
