21) Message boards : Number crunching : Validation inconclusive (Message 72813) Posted 15 Apr 2022 by GolfSierra Post: I am still doing N-Body work units and i have a total of 4 computers but will be stopping when World Community Grid starts back up +1
22) Message boards : Number crunching : Validation inconclusive (Message 72724) Posted 12 Apr 2022 by GolfSierra Post: I didn't restrict BOINC this way so I get NBody (16 CPUs) tasks. Each task needs 1:48 min to complete. However, I noticed that for some reasons some tasks freeze at different stages. The only way to restart them ist to exit BOINC and restart BOINC. This happens also during the night. I only can think of my antivir software that probably will suppress BOINC occasionally.
23) Message boards : Number crunching : Validation inconclusive (Message 72686) Posted 11 Apr 2022 by GolfSierra Post: As NBody doesn't seem to attract as many users as Separation (non-availability of a GPU version being a factor) this could take some time to sort itself out, even if some WCG users stick around to help out :-( I changed my profile to only receive NBody WUs and will keep this setting until WCG is back online.

25) Message boards : Number crunching : (0.892 CPUs + 1 Nvidia GPU) (Message 72635) Posted 9 Apr 2022 by GolfSierra Post: I have a combination of a RTX 3060 Ti and a Ryzen 9 5950x CPU. I tried different configurations and there was no difference in performance (calculating time) for a GPU task between 1 CPU and 0.25 GPU as one setup an 0.5 CPU and 0.25 GPU in another setup. The time to finish a GPU task increased, when I did 0.5 CPU and 0.1 GPU (ten GPU tasks in parallel), but that is because the capacity of the RTX was exceeded. Seems that the CPU is not the driving factor, regardless if you assign a full CPU or only 0.5 CPU to a single GPU task.
26) Message boards : Number crunching : opencl_nvidia_101 on RTX 3060 Ti (Message 72634) Posted 9 Apr 2022 by GolfSierra Post: I find the following with my GTX 1080 Ti's - 1X = 101 seconds 2X = 80 seconds My 3080's do no better 2X=75-82 seconds This Separation app is not very well optimized. I fully agree. Video cards have mage huge progress in capabilities, that's why GPUs are used for mining and not CPUs. However, distributed computing does not yet make use of this potential.
27) Message boards : Number crunching : opencl_nvidia_101 on RTX 3060 Ti (Message 72631) Posted 9 Apr 2022 by GolfSierra Post: I have a 3900x/3060Ti doing Seperation (GPU) tasks under linux using nvidia 510 drivers currently does 1 work unit in about 2:40. Is your 9:55 work unit time running 4 at once? Yes, I'm controlling MW@home through an app_config.xml. 4 GPU tasks in parallel, the setting ist 0.5 CPU and 0.25 GPU per task. Had no invalid results so far. You should give it a try. Beside the GPU tasks, my computer does 8 CPU tasks and 1 CPU task (16 CPUs) in parallel. I didn't enable all CPUs for number crunching to keep the CPU average temps lower. This is my app_config.xml <app_config> <app> <name>milkyway</name> <max_concurrent>12</max_concurrent> <gpu_versions> <gpu_usage>0.25</gpu_usage> <cpu_usage>0.5</cpu_usage> </gpu_versions> </app> <app> <name>milkyway_nbody</name> <max_concurrent>12</max_concurrent> <gpu_versions> <gpu_usage>0.25</gpu_usage> <cpu_usage>0.5</cpu_usage> </gpu_versions> </app> </app_config>
28) Message boards : Number crunching : Validation inconclusive (Message 72532) Posted 6 Apr 2022 by GolfSierra Post: The number of tasks listed as "validation inconclusive" has raised to 1922 out of 4604 total. This is a pretty bad proportion.
29) Message boards : Number crunching : opencl_nvidia_101 on RTX 3060 Ti (Message 72531) Posted 6 Apr 2022 by GolfSierra Post: My bad. Depending the sources I have found, the 660 Ti uses opencl 1.1 or 1.2, not 3.0.
30) Message boards : Number crunching : opencl_nvidia_101 on RTX 3060 Ti (Message 72525) Posted 5 Apr 2022 by GolfSierra Post: Well, the RTX 3060 Ti completes a WU in about 9:55 minutes. This is almost the same as with the GTX 660 Ti, only that I now can run 4 GPU tasks in parallel, with the GTX 660 Ti it were only 2 in parallel. The 660 Ti uses OpenCL 3.0 and CUDA 3.0 while the 3060 Ti runs still OpenCL 3.0 but CUDA 8.6. MW@home runs Seperation 1.46 WUs since 3-4 years now? And they are still using the old OpenCL 3.0 standard?
31) Message boards : Number crunching : opencl_nvidia_101 on RTX 3060 Ti (Message 72521) Posted 5 Apr 2022 by GolfSierra Post: I changed the grafix card on my rig from an old GTX 660 Ti to a RTX 3060 Ti. From the old set-up, I still have many WUs indicated with "opencl_nvidia_101" and to me it seems that the new card isn't much faster than the old one. Are there other WU types around that make use of the advanced features of a modern grafix card? My rig: AMD Ryzen 9 5950x RTX 3060 Ti Asus Prime B550M-WiFi 32 GB RAM Controlled by an app_confix.xml, I have 4 GPU tasks running with 1 CPU each and another 8 CPU only tasks. According to HWiNFO64, this keeps the average CPU (Tdie) just around 90Â° C, which still is within the temp limits of the CPU. It seems there is no difference in running GPU tasks with 0.25 GPU and 1 CPU or just with 0.5 CPU. Running MW@home on all 16 cores results in temps up to 94Â° C, but still no thermal throttling (HTC) kicks in. However, I don't like to have the Ryzen load at max all the time.
32) Message boards : Number crunching : Light Hash Rate (LHR) Video cards vs number crunching (Message 72419) Posted 1 Apr 2022 by GolfSierra Post: This might explain it: https://www.pcworld.com/article/395041/nvidia-lhr-explained-what-is-a-lite-hash-rate-gpu.html Unless the LHR cards are running the ETHash mining algorithm of Ether, the Nvidia drivers do nothing to any other code running on the card. The LHR mechanism looks specifically for the ETHash code. Since no project application contains any part of the ETHash code, all project applications or any other application other than ETH runs at full speed. If you run any other mining algorithm like what is used in Ravencoin, Ergo, or Conflux, the cards will run at the full hashing rate with no penalty or reduction. Thanks, got it. I'm no miner, so LHR will never effect me.
33) Message boards : Number crunching : Light Hash Rate (LHR) Video cards vs number crunching (Message 72369) Posted 31 Mar 2022 by GolfSierra Post: No Thanks, and your answer is based on what? Any more details to explain this, please?
34) Message boards : Number crunching : What is going on with my computer (Message 72362) Posted 30 Mar 2022 by GolfSierra Post: DCL, see https://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=4849#71901 others do have the same problems. It's not your rig for sure.
35) Message boards : Number crunching : Light Hash Rate (LHR) Video cards vs number crunching (Message 72355) Posted 30 Mar 2022 by GolfSierra Post: NVIDIA is offering many new cards with the LHR feature that is intended to slow down crypto mining and therefore make those cards undesireable for crypto miners. Will LHR also have a negative effect on crunching numbers for MW@home, WCG or other distributed computing projects?
36) Message boards : Number crunching : Validation inconclusive (Message 72315) Posted 29 Mar 2022 by GolfSierra Post: Thanks Tom, let's wait and see. I know there is no way to trigger the server to sent those missing third WUs. It might happen in the future or not.
37) Message boards : Number crunching : Validation inconclusive (Message 72309) Posted 29 Mar 2022 by GolfSierra Post: On my account page, there are already 518 results that are shown as "Validation inconclusive". Looking into the WU details, there are two results each shown and a third one says "unsent", so the server didn't sent a third WU for validation purposes. Will the third WU be sent or is this a side effect of the recent server trouble?
38) Message boards : Number crunching : KWSN optimized apps? (Message 72231) Posted 24 Mar 2022 by GolfSierra Post: From Seti@home, I know about a group that called themselves "The Knights who say Ni!" (Monty Python origin) or just KWSN. I wonder if there are optimized apps for MW@home around for number crunching developed by those guys as well. The KWSN vanished when Seti@home went into hybernation, never heard of them again.
39) Message boards : News : Server Trouble (Message 72049) Posted 18 Mar 2022 by GolfSierra Post: Just received another bunch of WUs and the completed ones were uploaded. We're making progress here! Thanks, Tom!
40) Message boards : News : Server Trouble (Message 72038) Posted 18 Mar 2022 by GolfSierra Post: Hi Walter, We are currently repairing the server, which has been running degraded for a couple weeks after a drive failure. We hope that things will be running smoothly by early next week. Apologies for the inconvenience, and thanks for your patience! Thanks for the update, Tom. Looks like it wasn't just a HDD that failed. Fingers crossed.
