We wish everyone a Merry Christmas!

An application for calculating SPT application tasks on the Raspbery Pi 5 x64 platform has been created and published.

Testing was performed on Raspberry Pi 5 x64 8Gb.

uname -a
Linux rsp 6.6.62+rpt-rpi-2712 #1 SMP PREEMPT Debian 1:6.6.62-1+rpt1 (2024-11-25) aarch64 GNU/Linux

One task uses about 1.5Gb of RAM
Calculation time was 50-55 minutes.
It is desirable that your device has active cooling.
The processor temperature was on average about 52C.

time ./spt

real    51m34.009s
user    51m31.552s
sys     0m0.682s

vcgencmd measure_temp | grep  -o -E '[[:digit:]].*'
51.7'C 

Best regards,
Project Team.

Thanks! My RPs will appreciate it. But 1.5gb? Yikes. Only 8gb versions (the max config) will be able to run 4 tasks at a time. Those with a 4gb or 2gb configurations will have to limit the tasks running simultaneously. Any way to make it so the tasks use less RAM?

Thank you for your feedback.
We understand your concerns about RAM.
At the moment, there is a way.

But it is highly undesirable to use it now (when the project is already running), since the project has been receiving your responses for over a year.
We are talking about all cruncher responses, from different computers and their systems.
At the moment, it is important for us to preserve the size of the prime matrix built in RAM.
It is this matrix that takes up 99.9% of RAM when our application is running.

It is possible, but not a fact, that we will reconsider this point when launching a new application for the range 2^64-2^127.
This application is still under development.
The current application can only count up to 2^64-1 (uint64_t=18,446,744,073,709,551,615).
This is a limitation of the primesieve library, which is a prime number generator for the matrix.
How to manage the application - a little about this is written in FAQ Part 1 p.3 https://boinc.termit.me/adsl/faq-en.php.

The last task from the range 1-2^64 will be calculated in about a year.
Although this moment depends more on crunchers, and not on us.

А можно узнать кто это - "мы"?

Очень интересно узнать, кто занимается разработкой нового Приложения.

Кстати, новое Приложение запущено в новом BOINC-проекте ODLK2025
https://boinc.mak.termit.me/odlk2025/

В этом Приложении используется очень маленький объём оперативной памяти.
Никаких проблем!

Приглашаю всех подключаться к новому BOINC-проекту!

I invite everyone to join the new BOINC project!

Можно не заниматься разработкой нового Приложения, а использовать уже разработанное и запущенное!

запускайте второе Приложение!
Работы хватит на всех.

Запустить второе Приложение - это просто импортировать его с проекта ODLK2025.
Думаю, Corporal не будет против.

А разработка нового Приложения вашими загадочными "мы" может продолжаться ещё не один год.

Кстати, у нас в ODLK2025 пока нет версии для Linux.
Вы могли бы её сделать в проекте SPT.
Вот прямо с неё и начните, пожалуйста.

Возможно, Corporal сможет сделать версию для Linux, но позже.
Сейчас у него пока есть проблемы с версией для Windows.
