1) Message boards : Generalized Fermat Prime Search : GFN-14 Consecutive Primes Hunt Season is open! (Message 135171)
Posted 11 days ago by stream
Today when I try to visit the stats page I get a warning message:

Website blocked due to a Trojan

Your Malwarebytes Premium blocked this website because it may contain a Trojan.

We strongly recommend you do not continue.

False positives are common for these "antiviruses". For example, my father likes "360total security" too much. Few times per year this "antivirus" completely deletes Boinc directory on his machine, claiming that LLR and Genefer are trojans. Best part of the story is that Boinc data directories are already configured as "do not check" exceptions. Not counting how many times he phoned me asking why his favorite game suddenly stopped working.

Double-checking of manual GFN-13 work is finished completely! It appears that not all GPUs used in manual search were rock-stable, as it seemed before. 220 candidates had bad residues, and few dozens of them somehow slipped out from result files. At least there were no missed primes. All candidates for GFN-13 now have and will have two independent results.

On the statistic page, I implemented another progress indicator - % complete by number of candidates tested. And it was surprise even for me, but GFN-13 project is 60% done. Although leading edge is at 202M (51%), we've already tested about 20% of candidates during search for consecutive pair. This gave good boost for overall progress.

Why is GFN-13 currently checking b's down at b=2-3M ?

Double-checking old work below 13.1M which was done manually in 2015 in one pass before Boinc project was started (see old and long thread "My little play with generalized fermat primes" if you're interested).

Since there is only one task per candidate and no need to wait for wingman, it'll be very quick. Really, only 2M remained to test, 8M-10M, which should took about 2 days (due to some reasons, ranges were loaded in random order and sometimes mixed with "normal" tasks)

Early I though that check will be purely formal, but it seems that few dozens of candidates were not tested, at least their residues do not exist in results files from manual tests. A chance to miss a prime is very low, but let's see.

Did you tried to join other projects except PrimeGrid recently? Some of Boinc setting are global for all projects. Almost all servers are not aware about extra PrimeGrid venues. If you'll edit your global settings on these servers, all your extra venues will be deleted.
5) Message boards : Problems and Help : Problem with weak account key (Message 134626)
Posted 32 days ago by stream
Shutdown client and manually edit key ("authenticator") inside "account_www.primegrid.com.xml" file (located in Boinc data directory, default is \ProgramData\Boinc on Windows).

That's definitely not the problem. The image was created *before* it was attached to any projects.

As soon as you've installed Boinc, it immediately created CPID (unique host id). Then you've cloned it to another computer, and... boom!

I think I know what the problem is, and, if so, I think I know how to correct it, but it's not worth the effort.

Indeed. But if anybody else is curious, it could be fixed by two ways:

1) Stop Boinc, delete client_state.xml in data directory, start Boinc.
2) It will heal himself over time - when such error is detected, CPID is automatically regenerated. But tasks affected by this "training" will be abandoned and lost, so use short ones.
7) Message boards : Problems and Help : Tasks not switching per preferences (Message 134088)
Posted 48 days ago by stream
Yes, but from my point of view such manual micro-management is useless. Let the Boinc choose. It will automatically select which task must be run first, based on their estimated durations and deadlines. Unstarted tasks could be automatically aborted, this is normal procedure.
Also most peoples here run only one sub-project at time, it's simpler to manage.

It switches between different projects only. All your tasks are from one project (PrimeGrid), so no switching.
9) Message boards : Generalized Fermat Prime Search : GFN-16 MEGA Prime Search starts March, 14, 2019 (Message 134018)

Is this search still progressing as fast as it did in the beginning? Leading edge seems to be close to bmin+142000 now. /JeppeSN

Very close to. History could be recovered from messages in this thread and your question made me curious.

Start: Mar 13
100K 1st pass completed: May 17 (~ 64 days)
100K 2nd pass completed: Aug 21 (~ 94 days) Double-checking was boring, some peoples quit, so it took and extra month.

Currently tasks are immediately double-checked, so if leading edge advanced by 50K it's equal to 100K of single pass. Roughly assuming that today is 60 days since end of first 100K, estimated completion time for 50K will be 50/42*60 = 72 days, which is a bit slower then in the beginning (64 days), but very close.
10) Message boards : Problems and Help : Option to set Priority to Normal instead of Low? (Message 133657)
Posted 60 days ago by stream
"no_priority_change" option has no effect on applications which use wrappers (including LLR). It will change priority of wrapper. And most wrappers are written in "copy/paste" style and share same code - they always forcefully run their applications at idle priority regardless of Boinc settings.

Luckily LLR have it's own priority management, but you must change protected llr.ini file, so you must use app_info.xml which is not simple and have lot of disadvantages.

Another solution is to write scripts or use existing extra tools which will periodically check status of running processes and change priority if necessary. On Windows, I think Process Lasso could to this. On Linux, it can be written in small shell script.
