I did notice that, and I am no math gene, but if I remember correctly, 1 WU took about 20min on the 7850, and now 8 WU's takes about 40min each. I can deal with that. On my GTX 680, well... Lets just say that my 680 card isnt really up for the task(s) hehe :) |

Lets just say that my 680 card isnt really up for the task(s) hehe :) If my experience applies, it sounds like you should scale up 20 X 8 = 160 minutes if there was no loss in speed. It sounds like we are talking about 40 X 8 = 320 minute total. If I am not confused that is about a 50% reduction in processing speed per task. (1440 / 20 ) * 1 = 72 tasks a day. (1440 / 40 ) * 8 = 288 tasks a day. So if the number you gave me are fairly accurate you are seeing a very large increase in production. Congratulations!

Lets just say that my 680 card isnt really up for the task(s) hehe :) . . Hi Tom, . . If one at a time takes 20 mins that is 20 mins/task, if 8 at once takes 40 mins then that is 40/8 =5 mins/task, that is a 75% reduction in processing time or a 400% increase in speed (20 mins = 4 tasks instead of 1). That seems an unlikely improvement unless it was very badly configured when running 1 at a time. If running onesies under SoG the GPU tends to run at over 90% efficiency but to achieve that level of improvement it would have had to be less than 25% efficiency. . . Considering he is running Cuda42 on the Nvidia card I am guessing it is also very badly configured and would achieve much better results if he changed over to SoG and ran onesies. It would probably just about halve the run times per task on that rig. Stephen ? ? |

Call me insane (I'm ok with that!) . . When testing I have run 8 at a time on GTX970s with 4GB without trouble. So the cap is only a matter of how far you want to push it and how much you are willing to reduce the operating efficiency. Generally it is better to run SoG and just do the one or maybe 2 at a time.

Generally it is better to run SoG and just do the one or maybe 2 at a time. No, that is not true. Sorry Stephen.... The rule is, how much Memory does the GPU have and how much of it is available for use in OpenCl applications. The 970s only has 3.5GB. Yes we all know it says 4 on the box but it's really only 3.5 Nvidia cards are limited to 27% of available RAM for use in OpenCl. Intel and ATI cards are up around 50-67% of the RAM of the card. So when setting the commandlines for SoG, you have to figure in how much RAM per work and then figure out how many parallel work units you can run. With 980ti you can run 3 instances and with the new 2080Ti you can run4 instances. Since I've never had an ATI card, I can't tell you how many you can do but it's fairly obviously that it will be more than what can run on Nvidia. Good luck. Z

So when setting the commandlines for SoG, you have to figure in how much RAM per work and then figure out how many parallel work units you can run. All I care about it what produces the most work per hour. For CUDA50, depending on your hardware, 2, 3 or even 4 WUs at a time would produce the most work per hour. For SoG, no matter what settings I have used, running 1 WU at a time has always produced the most work per hour. Just because a card can run more than 1 WU at a time doesn't mean it's a good idea.

For me running 3 at a time under SoG was much faster than 1. The person I know currently running 2080Ti, it's 4 SoG at a time. It's the GPU that makes the difference.

From Lunatics installer v.045, which app is the best for a nvidia RTX 2060 super? Is is Cuda 50 or SOG? |

On Windows machines currently SoG wins over CUDA. However it would appear that some recent Windows driver installations don't have the OpenCL driver in the pack :-( So try have a look at the drivers from nVidia to see if they are any better.

Seems that the driver doesn't suport opencl. any help? You don't have the Nvidia OpenCL driver installed. BOINC is only detecting the Intel OpenCL driver for your iGPU. You need the Nvidia one too. Download the Nvidia driver package directly from Nvidia. It would also be smart to use the DDU graphics drivers uninstaller to clean out all the remnants of previous drivers. Then you still have to figure out a way to prevent Microsoft from installing its broken version of the drivers that are missing the OpenCL component.

Any other series runs fine on the gpu. I think the driver is at fault. He is running the latest 436 driver and I think that is the issue. What driver are you running? I have processed the very same WU species he is exceeding time limits with no issues on either cpu or gpus.

He can run BLC and other Arecibo tasks but those VHAR tasks are all erroring out with time exceeded and no progress being shown. The 436 drivers are what I would consider beta since they added all kinds of experimental features like integer scaling. https://setiathome.berkeley.edu/result.php?resultid=7993094550 Seti@Home classic workunits:20,676 CPU time:74,226 hours A proud member of the OFA (Old Farts Association) |

Not the problem. Now at least two separate accounts with Windows 10 and 436 Nvidia drivers are erroring out all VHAR tasks with time exceeded errors. I don't call that coincidence. And all other hosts running those same tasks on different platforms and different drivers successfully complete them normally in the usual task times.

How do I tell VHAR tasks from all other types of tasks? More than half of the SETI@Home GPU tasks on my computer today have completed much faster, and apparently properly. I am using a 436 driver, so I'll look for an older driver. Does it matter which one as long as it is recent? |
