11) Message boards : Project Staging Area : PRPNet Credit may be Irregular Until Further Notice (Message 153185)
Posted 264 days ago by ReggieProject donor
I have got two different UserID's among the results, that are actually the same - 'Masse' and '1455014', due to some confusion when editing the related ini file. Same applies to TeamID ('Digitronics' and '8601'). In the 'BOINC world' UserID and TeamID are pure numbers.


Yes, it has been handled correctly. In the future, please keep threads on topic.

Is there any way we could get a weekly update here as to how many tasks are left? I just find this strangely fascinating. Even if its just a rounded approximation?

All work has now been loaded. You can now just check the front page to see how much work is left.

New AP26!!!

A new AP26 (Arithmetic Progression of 26 primes) has been found. The finder is Jaroslav Čampulka (oldjerry SETI) of the Czech Republic. Jaroslav Čampulka is a member of the Czech National Team.

The AP26 was returned on the 26th of November 2021 0:35:43 UTC. It was found by an NVIDIA GeForce RTX 2080 Ti on an AMD Ryzen 9 3950X 16-Core Processor running Microsoft Windows 8 Professional x64 Edition. It took about 8 minutes and 37 seconds to process the task (each task tests 100 progression differences of 10 shifts each).

The AP26 task was double checked by Raymond Ottusch (RaymondFO*) of the United States and was returned on the 27th of November 2021 5:02:47 UTC. This task was run on an NVIDIA GeForce RTX 2080 on an Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz Processor running Ubuntu 18.04.6 LTS. The double check took about 17 minutes and 37 seconds to complete.

The progression is written as 461497054041390487+108734395*23#*n for n=0..25. Credits are as follows:

Finder: Jaroslav Čampulka
Project: PrimeGrid
Program: AP26

The original AP26 CPU program was written by Jaroslaw Wroblewski and adapted to BOINC by Geoff Reynolds, and the GPU program was written by Bryan Little and Gerrit Slomma.
The 2016 CPU and OpenCL versions of AP26 were updated by Bryan Little, Iain Bethune, and Sebastian Jaworowicz.

All application builds by Bryan Little and Iain Bethune

The AP26 will be listed in Jens Kruse Andersen's Primes in Arithmetic Progression Records page under the section(s):


Congratulations!

I just did PRPNet credit a few minutes ago. From now on, it should be fairly regular again.

Posted 435 days ago by ReggieProject donor
Note that about all of this is from memory and could be wrong, but here's what I remember:

When we ran CW-Sieve before, it only supported CPU and Nvidia GPUs. We would really like the to restart the subproject with support for AMD GPUs as well. Of course, speed improvements are always nice as well. I believe it's been close to a decade since that software was written so I imagine new CPU and GPU features could provide considerable speedup if the software supports it.

IIRC MTsieve was able to outperform one of the old programs but not the other. If we do use MTsieve (which I think is likely unless the old app outperforms it), we'll also need to do more testing and write/adapt a boinc wrapper to go with it. This is in addition to admins going through the old server side code, as well as doing some initial sieving to prevent initial uploads from being huge.

Posted 436 days ago by ReggieProject donor
Is a forthcoming CW-Sieve subproject a thing or just speculation? This is my first hearing of it. I for one welcome it!

It will come eventually. We don't have any sort of ETA, but it's on the timescale of months or maybe even years. It comes down to when admins and/or developers have time. I got WW up over the course of a few months when I was unemployed with lots of free time. That's no longer the case.

Posted 438 days ago by ReggieProject donor
Chances are strong that we'll use a new app that is not Nvidia specific. Not set in stone at this point, as it requires a lot of effort from a few people to get CW-Sieve up again.

Posted 456 days ago by ReggieProject donor
Due to a fair amount of chaos in my life starting now, PRPNet credit may not be granted every Saturday like I've been doing. It may be a few days early, late, or even miss a week or two. I apologize in advance, but I'll do it when I can. I'm guessing I can go back to every Saturday again in the middle of August, but I'm not guaranteeing anything at this point.
