Replication of 2 allows data to verify that they match. Replication of 1... some bad or broken data can randomly and silently get past it and show up as "Valid" as there are no wingman computer to verify result. GPU Calculation errors sometmes caused by overclock, undervolt, automatic updates to windows drivers, blown capacitor or just failing hardware. Please check this statement from Uplinger with regard on validation. FWIW, I think it is more safe to trust the WCG Tech Team in the way they are handling things than the average user like us with no insight at all. |

Ok, so that partly explains about just having replication=1.But is those single invalid double resend, replication=3, and server abort / triple valid a bug? This can possibly go from "yay got a few GPU task" to "No, server aborted". So far, OPNG server abort didn't happen to my computer yet. |

But is those single invalid double resend, replication=3, and server abort / triple valid a bug? It's not a bug. It's the way the server is set up. An invalid sends out 2 more copies of the task for comparison. First 1 returned that matches is valid. No need for a second so the server aborts it. In some cases both tasks have started before 1 is returned. In that case both the resends can be valid. Hope this clears up the subject.

An invalid sends out 2 more copies of the task for comparison. I guess OPNG is different from ARP1 where their 1 invalid just send 1 more copy.Now on to work unit availability, I do get a few OPNG tasks, about 10 per day, with the use of report_results_immediately in app_config.xml while running CPU tasks to get more work more frequently.

Just noticed a few more OPNG units sailed by while I was asleep... not as many as yesterday. I'm glad to see more coming, even if they're few and far between.

I got my first 5 jobs for an Nvidia GeForce GTX 1050 Ti. It seemed to only be able to do 1 at a time, but they only took 6 minutes each. Happy days.

I hope the WU sending will ramp up, we are hungry for GPU computing :)

This is a bust so far for me. I've yet to receive a single production GPU WU after doing fairly well receiving them with the beta. Lots more cards chasing production units I presume. Or those setting scripts to check as often as allowable are vacuuming them all up...

Or those setting scripts to check as often as allowable are vacuuming them all up... A combination of low wu production, more folks interested now that it's not beta, and the script kiddies trying to suck up all that they can get. No way to stop the script kiddies as far as I know. The kitties are not getting any here either.  [Edit 1 times, last edit by kittyman at Apr 8, 2021 5:42:31 PM] |

I received GPU jobs on all three of my machines with discrete graphics on Tuesday.
----------------------------------------2070 Super and 1060 completed them in 2-4 minutes each while they were already doing AI upscaling. An older GT 970 took around 15 minutes per job. I only got 4-5 jobs per machine, so I hope we get more in the future; much faster way for everyone to contribute. [Edit 1 times, last edit by ShooterQ at Apr 8, 2021 6:35:22 PM] |
