21) Message boards : Wieferich and Wall-Sun-Sun Prime Search : WW is broken (Message 152119)
Posted 25 days ago by Profile Michael GoetzProject donor
We're aware of the problem with WW tasks. New work generation has been disabled. We'll keep you informed as more information becomes available.

I think the camera is shooting video at 30hz while rotating at 60rpm.

The video is old. 60 hz cameras weren’t that common back then. I think 30 hz is more likely.

The audio does sound like 60hz, so it likely is.

Video is shot line by line, so with the camera rotating twice as fast as it is scanning, it is going to capture the image twice in each frame. This effect is exactly what you see in the video.

My two cents.

This is the best video.
It is perfect.

Yup. Definitely an incredible video.

Something to think about next time your phone, in a case, drops from your pocket onto a carpeted floor, and the screen cracks.

Since an LLR2 challenge like this one contains two very different types of tasks, I wonder if it would relevant and technically possible to split the column Tasks on the challenge leaderboard top_users.html into two columns, Main tasks and Proof tasks? /JeppeSN


It's unlikely to happen.

Many challenges, even without fast DC tasks, have more than one type of task. Take, for example, the GFN 21 / 22 / DYFL challenge. There's too many possibilities for how a challenge can be set up to try to make a generic report that breaks it all out. And, trust me, the code that does those challenge reports is hideously complex as it is in order to be able to handle all of the existing challenge types. I do not intend on making it even more complex.

They create the same problem for everyone. Just ban them. Maybe a message to them would be picked up by someone who can contact us to clarify the situation. If they *do* return & fix their machinea they can be reinstated.


Exactly what problem is that?

Months later
Please ban this user/host. Set a counter on allowable tasks per day and reduce the number for failed tasks.

There actually is a limit, but it's set very high. We don't want to stop people with very fast computers running very short tasks from getting work.

Other than causing a delay in wingman tasks completing, and thus delaying credit, is this causing any problems for *you*? Obviously this person's computer has a problem, but is it causing problems for other people?

How are the leading edge digits on the Subproject status page calculated? It says 4,796,754 is current leading edge digits which would correspond to n = 4306102 for base 13. It's very close to the minimal n in progress, also for the other bases. Is there something with the leading edge calculation?


You're actually asking the wrong question. How the digits are calculated is straightforward. The real question is how the "leading edge" is defined.

What does "leading edge" mean? For a project like GCW, we send out tasks in size order. It would be (very slightly) easier to send tasks out in "n" order, but as n grows larger the difference in size, calculation time, and credits between tasks in the different bases would grow larger and larger. Different tasks would vary greatly, and it would be harder to configure host computers to efficiently run tasks. Instead, we send out tasks in size order.

You already knew that, of course.

Which brings us to the heart of the question. What, exactly, does "leading edge" mean? Does it mean the largest task that's been sent to a host? The largest number that's been loaded into the server? The largest number that's been turned into a workunit? Something else?

In the case of that particular page, leading edge is defined as the largest number that has been turned into a workunit. On the other hand, the calculation of leading edge for the challenge statistics is different; that calculation is the based on tasks actually sent out to hosts.

It has been proven as prime. Congratulations on such a rare find.

It has been more than 20 years since the last +1 primorial has been found. Maybe PrimeGrid can find one of those in the near future as well.

IMO although this is just a mega prime and wasn't found via BOINC, I think it requires a news entry on the main page due to the rarity for primes of that form.


That definitely is going to happen. (It was planned all along.)
29) Message boards : Number crunching : Where are the "Badges" stats? (Message 151873)
Posted 40 days ago by Profile Michael GoetzProject donor
I used to be able to see my "Badges" stats when went to the "Your results" link in BOINC Manager. It seems to be gone. Can we get it back?


The results page never showed badge information.

You can view your badge information at https://www.primegrid.com/show_badges.php or a summary of your badges can be seen in the main account page at https://www.primegrid.com/home.php .

The latter of those two links is what you see when you click on the "Your account" button in the BOINC manager. Perhaps that is what you were thinking of.
30) Message boards : Problems and Help : Radeon RX 6700XT Error on GFN-15 trough GFN-19 (Message 151754)
Posted 49 days ago by Profile Michael GoetzProject donor
Let's try to narrow down the circumstances under which the error is happening.

You're both reporting that GFN-15 through GFN-19 are failing, while GFN-20 and higher are working. I can't verify this, so I'll take you at your word. Between the two of you there's only a single failed task currently in the database.

GFN15 through GFN-19 use a different transform (OCL2) than the larger GFNs. It appears, therefore, that the problem is limited to OCL2.

Both of you have similar, recent vintage AMD GPUs, and are running Windows 10.

I do not know what the problem is, but I can tell you that there are currently 1835 successfully completed and validated GFN-16 Windows AMD tasks. Whatever this problem is, it's not affecting all AMD GPUs.

Narrowing the search down to AMD 6600 and 6700 GPUs, there's 6 computers with one of those GPUs that have completed at least one task in the relevant GFN apps. Two of them have successfully completed and validated those tasks, so we know it *is* possible for your GPU models to run these tasks. Both of those computers are also running Windows 10.

Beyond this I'm afraid I can't really help you. I've never owned an AMD GPU and I'm not familiar with them. But since there's examples of your GPU models successfully completing these tasks, it's likely that it's possible to get yours working too.
