The person to contact is Eric Korpela... Next would be Jeff Cobb.

Unfortunately I didn't get a reply from Dr. Korpela and missed any acknowedgment, so I've written to Dr. David Anderson cc Jeff Cobb. I think that the more on the team that are aware, the better. Also as Dr. Anderson has been working on Nebula for years and this has the potential to do serious damage to its output, I think he should definitely be aware (I'm sure he probably is but we haven't had any wide-ranging official word on this so that would be nice too.)

Edit: And Jeffrey A. Smith is the latest person to reply indicating that they have disabled GPU computing.

Yes if you read the release day reviews of the Radeon Navi 5700/XT cards that include business and scientific computing benches in their benchmark suite, you can see the testers/reviewers comment that the OpenCL compute was not working. Either the applications would crash or not run or produce invalid data. Consensus was the Navi cards were "not ready for prime-time" for OpenCL computing.

Yes, other projects are having issues with the cards. Some don't. Depends on the application and data structures I assume.

Thanks, Wiggo! Haiko_N and Juraxell were already in the list and pestered. Wojciech Knapczyk doesn't have an affected card so may have removed it if was already notified in the "Invalid Host Messaging" thread or otherwise.

I am going to update my list with annotations and check whether the ones who haven't replied are still producing garbage; some of them may have offlined but not replied.

I'm sorry about that 1, but I rechecked that w/u and the culprit was actually Borktron 10682716 ( I really shouldn't do this late at night) and alffrommars 9024750 also turned up this morning.

Cheers.

Excellent and no worries... I've pesterposted alffrommars. I also found a couple more. Here is the complete list with participant (not computer) IDs so it's fresh. Please, to all, don't quote the whole thing in a reply. Thanks.

Italicized names have replied and indicated they are disabling their affected GPUs.
Struck-through names are confirmed to no longer be producing these bad results, ie via disabling GPU computing.

Another computer from toby:

toby 8772813

I don't PM people about this, it's usually not worth it.
99.9% never replies. Most of them don't even know about this forum.

This is out of control by now, and the database is badly corrupted, and the scientific results are totally unreliable.

The number beside the names Sten are user ID numbers not computer numbers unless they're "Anonymous" users. ;-)

Cheers.

Thanks! However I think that was the one I have in there as the ID numbers I've listed are the participant IDs... toby's RX 5700 host is 8772813. Edit: And Wiggo beat me to it. :^)

I am hoping that, as with epidemiology, once a certain threshold in the population is crossed, "infectable hosts" will no longer statistically find each other, so a small percentage of responses as Wiggo noted may result in a much higher reduction in cross-validations. Unfortunately all we have is hope right now.

---

I logged the participant IDs that I contacted to prevent any ambiguity of who was contacted as there are many duplicates, for example there are dozens who are exactly "Eric".
Edit: Also in case any changed their display names.

---

And I just followed Mr. Kevvy's lead. ;-)

Cheers.

Ok this is crazy. On ONE system alone (and my slowest one even) I have five (5) Invalid tasks from the last day alone, that were cross validated by the SAME two systems with RX5700s. how is that even possible. I was under the impression that WU distribution is more random than this.

I see they are already on the notification list, it's just wild that I would be matched up with the same two systems in such a short amount of time.

got a new one to send a message to:

Kevvy, just a suggestion. I would use the strikethrough to indicate the users who have replied and agreed to remove the GPUs. It will be more visually clear.

I see this constantly with blocks of consecutive work units cross-validating from the same two hosts due to the volume of work they are requesting.

Thanks, Ian! gunsnammo 137399 has been pestered. :^)

Also I am saving strikethough for when I validate they are actually gone including ones that didn't reply.

{edit}
. . Well maybe change them to a smaller font or underline them. Apparently Ian has the same problem I do, the difference between normal and italic is too small to readily identify in just the names.

:)

I've also made PSA posts about this on overclockers.com and Reddit in r/SETI imploring anyone running RX5700/XT to please remove them from the project immediately. Hopefully at least a few more people see the posts and comply.

That sort of thing actually happens a lot- as you both request work at the same time, and get it allocated at the same time, so you will get to share groups of WUs with a particular Wingman.
