Mainly the upload server yes, but the download server has been problematic too from time to time. Now though, it seems OK, at least for the moment.

You are adding to the problem with 120 second loop to retry transfers. 900 seconds would be more reasonable, that is enough to stop transfers going to multi-hour backoffs but won't hammer the servers that are already overloaded. Paul. it's necessary when you have systems as fast as mine and can process the volume of data they can. i don't even run this script on my single 1660 Super system as it's been able to manage things mostly itself. but this is a stress test afterall. if uplinger wants to know what it takes to support everyone, I'm happy to oblige.

There is a solution to reduce GUI lag during OPNG crunching?

We're dumping some truly enormous computing power into the system, so I can't be too surprised to see some teething problems. At least the download side hasn't been showing issues; IMO that's more irritating since it interferes with work fetching.

Make this file app_config.xml in this path: C:\ProgramData\BOINC\projects\www.worldcommunitygrid.org
Change the .1 to a value you want to be 1/(tasks per GPU). For me .1 gives me 10 tasks per GPU. <app_config> <app> <name>opng</name> <gpu_versions> <gpu_usage>0.1</gpu_usage> <cpu_usage>1</cpu_usage> </gpu_versions> </app> <app_version> <app_name>opng</app_name> <plan_class>opencl_intel_gpu_102</plan_class> <ngpus>1</ngpus> </app_version> <report_results_immediately/> </app_config> |

Mainly the upload server yes, but the download server has been problematic too from time to time. Now though, it seems OK, at least for the moment. On 3 of my PCs with NO high-end GPUs, I set the system to crunch 2 and 3 tasks simultaneously. However, the upload queue builds up relatively quickly, so I guess I will revert back to 1 task per GPU. I was playing with the idea to use this 2 or 3 task per GPU setting also with my main cruncher with two RTX3070 inside. However, I refrained from doing it, because the upload queue would probably be filled within minutes, blocking any new downloads :-( What I would need is a script for Windows10. |

Even with my mid-tier dual GPU system, I have been struggling to clear my upload queue for hours. It took nearly 5hrs now to clear the whole queue that I discovered this morning. Sadly, the stuck uploads prevented my system to grab new work for a few hours. My main system can crunch between ~80-100 WUs/hr, so I can't even begin to imagine what volume Ian's systems rip through :)

At least the download side hasn't been showing issues; IMO that's more irritating since it interferes with work fetching. I do have issues with fetching work. I'm able to grasp enough CPU work but I'm continuously running out of GPU workunits. When I fetch for work I usually get 0, 1 or 2 GPU workunits, not enough to keep my GPU busy (I complete them in +/- 2 minutes). Is there a way to cache more GPU work? I also have upload issues like everyone else but that's not really blocking my machine. |

So are the OPNG WU's going to keep coming after the 3-day stress test? If they are, I'll go buy a better GPU :-) They will go back to their original state, that is, around 2,000 work units will be sent every 30 minutes.  - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |

There is a solution to reduce GUI lag during OPNG crunching? I don't know but that sounds like something that is more related to your GPU. I can even play games running OPN on my RX 550 but I had massive GUI lag while running older GPUs on other projects. Maybe simply set GPU computing to when the system is idle to avoid this problem. - AMD Ryzen 5 1600AF 6C/12T 3.2 GHz - 85W - AMD Ryzen 5 2500U 4C/8T 2.0 GHz - 28W - AMD Ryzen 7 7730U 8C/16T 3.0 GHz |
