[PrimeGrid] PrimeGrid will be offline for server upgrades

We're upgrading to new servers sometime within the next week. With minimal warning, all PrimeGrid servers will be down for several hours. Discord, of course, will remain available. Discussion and more information will be available on Discord as well as on the the forums. The forums will be offline during the upgrade, however, so Discord is where we can be reached during the upgrade. EDIT #1: The plan is for the server upgrades to begin at 15:00 UTC Friday.

[PrimeGrid] PPS-Sieve, PPSE, GFN-15, SGS, and AP27 are shutting down

We recently took a look at the projects that we are running and decided to make some changes. For more information, and discussion, see this thread: PPS-Sieve, PPSE, GFN-15, SGS, and AP27 are shutting down. (Note that the plan has since changed and PPS-MEGA is shutting down instead of PPSE.)

[SRBase] New apps plan

We have started testing new applications for SRBase on a BOINC test server, which are already used at PG, i.e. PRST is intended to replace llr2. Since there are still some code changes being made, everything is moving around a bit.

What are the advantages of the application?
- no more restrictions on the speed of the Gerbiczcheck (at the moment there is a performance loss of up to 40%)
- native application, no wrapper needed anymore

The following errors from the wrapper are then history:
- restarts of the BOINC client do not reset the CPU time to 0
- linux wrapper suspend issue
- better progress bar
- other general wrapper issues

Running app_config.xml files that are based on llr2 would then have to be readjusted, otherwise errors will occur in the calculations.

A public test will follow, time uncertain.

[ODLK1] Server problems

Hi,

during the holiday one disk of the server suddenly died, so it gets unavailable.

Unfortunately I come back from holiday a week later, so all workunits and credits were already time out at that time.

Disk died on 20 Aug during the day. The DB is the one of 8:00 as it from a clean backup (all WU and result where not touched from the disk damages, however some WU may be missed into the DB for credits, but not for the results collected).

As the server were using an old SO that soon will go out of update, I go for installing even the new version of the server, for having years of updates.

Now there is still some problems in configuring all the services as there are incompatibility from old to new libraries, so you should considerate to reactivate your ODLK1 calculation for the next week at least.

However, bookmark this page: http://boinc-status.multi-pool.info/

This is in another server, so in case of problems you can see the state of ODLK1 there (unless the internet connection is broken, as both uses the same one).

Thanks

[PrimeGrid] Sieving for Proth Prime Search to be suspended

The PPS Sieve has advanced well beyond the searches that use the sieve, and it will be many years before more sieving is needed. We are therefore suspending the PPS sieve. The CPU apps will be removed 30 days from now, on October 4^th. The GPU apps will be removed, and the sieve fully suspended, somewhat later. More information, and discussion, can be found here.

[Gerasim@Home] Gerasim@home:

Добрый день, ребятки. Появилась тут проблема:

ОС и загрузчик Герасима оказались на разных дисках. Вылечить - недолго. Долго делается резервное копирование системного диска. (сейчас, загрузчик хоть и кривой, но работает).

Как восстановить загрузчик Windows 7 и Windows 8
Источник: https://nastroisam.ru/kak-vosstanovit-zagruzchik-windows-7-i-windows-8/

При этом, работа Герасима будет приостановлена, а то и вовсе проект будет недоступен. Теоретически, всё займёт не больше 1 часа, а там - кто его знает. Приём посчитанных заданий будет разрешён, а выдача новых заданий запрещена.

====

Good afternoon guys. There was a problem here:

The OS and Gerasim's bootloader ended up on different disks. Healing is short. It takes a long time to back up the system disk. (Now, the bootloader, though a curve, but works). How to restore the bootloader of Windows 7 and Windows 8

Source: https://nastroisam.ru/kak-vosstanovit-zagruzchik-windows-7-i-windows-8/

At the same time, the work of Gerasim will be suspended, or even the project will be unavailable. Theoretically, everything will take no more than 1 hour, and there - who knows. Acceptance of computed tasks will be allowed, but the send of new tasks will be prohibited.

[PrimeGrid] 321 Prime Found!

On 5 July 2023, 17:48:23 UTC, PrimeGrid's 321 Prime Search found the Mega Prime: 3*2^20928756-1 The prime is 6,300,184 digits long and will enter Chris Caldwell's “The Largest Known Primes Database” ranked 19th overall. This is the largest known prime for the 3*2^n-1 form. The discovery was made by Arno Lehmann (Zyfdnug) of Germany using an AMD Ryzen 9 7900X @ 4.7GHz with 64GB RAM, running Debian GNU/Linux 12 (bookworm). This CPU took about 6 hours, 20 minutes to complete the probable prime (PRP) test using LLR2. The PRP was confirmed prime on 5 July 2023 by an AMD Ryzen 9 5950X @ 3.4GHz, running Linux Mint. This computer took about 2 hours, 46 minutes to complete the primality test using LLR2. For more details, please see the official announcement.
