However, I have thought more about this, and I think it may be unfortunate, in the case of Proth (Mega) Search, to advance all k between 5 and 1199 in the same pace, in the way described by Jim here. The reason is that small k, let us say k<20, are much more attractive to search at a given size (say n=6M, as an example), than large k, such as 1000<k<1200.


Does the data back this up?

Fermat divisors found at PG, by K:

+------+----------+ | k | count(*) | +------+----------+ | 9 | 1 | | 25 | 1 | | 27 | 1 | | 57 | 1 | | 131 | 1 | | 151 | 1 | | 183 | 1 | | 193 | 1 | | 267 | 1 | | 329 | 1 | | 519 | 1 | | 651 | 1 | | 659 | 1 | | 1705 | 1 | | 2145 | 1 | | 3771 | 1 | | 4479 | 1 | | 7333 | 1 | | 7905 | 1 | +------+----------+


We've actually found more Fermat Divisors above 1200 (PPSE range) than we have below 100. Only one was found below 20. That's obviously a very simple metric that ignores a lot of important stuff, but it's not all that clear that we have to be focusing on small k's.

I say this not to shoot down the idea, but rather to start the conversation going.

Hey Michael et al.

Any chance you could add an extra column to the 'badges' page to show 'position' relative to credit earned
eg. Sob LLR 1,234,567 Amethist 2,000,000 Ruby 765,433 1,234th place

Just asking?


That's Jim, not me. If it were me, the answer would be no because it's an expensive calculation.

I cant remove and reattach. the remove button is greyed out.


Did you select PrimeGrid before trying to click no the remove button? If you have only one project, it's not obvious that you need to select that project prior to clicking on the buttons.

Are you using an account manager such as "BOINCStats BAM!" ? If so, first tell your BOINC client not to use the account manager.

If all else fails, you can uninstall BOINC, delete the BOINC data directory, and then reinstall BOINC.

This might not be the correct thread and if so please move it.

I've gotten several ghost tasks all of which are multi-threaded. They didn't show up on my workstations and yet they did show as being running. Then of course I get a time out error on them. Was just wondering why this might be happening. I've noticed it a little more during this TdP. At first I thought it might be some tasks I aborted but those were tasks I could see and abort.

Cheers


It's a random communications problem and has nothing to do with anything you're doing. Just ignore it.
