Dear crunchers!
Today marks exactly one year since we launched our project.
Official start time of the task generator 2023-07-25 16:00 MSK (25 Jul 2023, 13:14:50 UTC https://boinc.termit.me/adsl/forum_thread.php?id=6&postid=133#133).

During the year of your active work, you helped us process batches 87 to 137.

Accordingly, you helped us get results in the range of numbers from 4663878384525935453 to 10160928384525935452.
This is for today.

At the same time, as you remember, work on the 87th batch was suspended for 9 months.
But now you have almost counted it, there is not much left at all.

All results are published on the project page https://boinc.termit.me/adsl/spt_explore.php
We show rare solutions on the page https://boinc.termit.me/adsl/spt_explore.php?rare

Over the past time, the work of our server has not stopped.
50 batches were calculated (137 - 87 = 50).
There are currently more than 19187101 records in our database (this is four times less than Thomas).

And this is in just one year!
Fantastic!

The last full batch (for 128,000 tasks) will be number 207.
And the final partial batch 209.
That is, we still need to count 70 batches (207 - 137 = 70).

We are grateful to Thomas Brada for the project code.
Thomas put an incredible amount of effort into developing the code for the SPT project.
Starting the project 18 Oct 2019, 19:56:20 UTC 
https://boinc.tbrada.eu/forum_thread.php?id=3058&postid=3673

We understand that not many completed batches are visible on Thomas's website.
In three years, batches 44 to 84 were completed.
https://boinc.tbrada.eu/forum_thread.php?id=3055&postid=3665
16 Oct 2019, 15:26:22 UTC
Batch 44, range 500304494994471000..500309661688072493 with the new app.
(this is the official launch date for Thomas' new app called SPT).
This is the application currently running in our project.

Thomas's last, unfinished batch:
https://boinc.tbrada.eu/forum_thread.php?id=3055&postid=4761
Posted: 21 Aug 2022, 13:02:40 UTC
Batch 85: 4100001000000000000 .. 4663201000000000000 -1
(Approximate number of records 85000000)

And we also understand that Thomas constantly needed to stop the project, change the code, and reissue tasks in order to achieve the best results for the program.
This kind of work takes a lot of time.

Therefore, it is impossible to compare our two projects in terms of speed.
Thomas had a much harder time.

Our plans:
- improve the performance of the results page.
- count to the end 2^64.
- analyze the data received (today, data from batches 89 to 133 have been fully confirmed).
- we may have to recalculate the initial batches (that is, from 0 to 4663878384525935453) since the database on Thomas’s website has several tens of thousands of incorrect values and there are gaps in large ranges of numbers.
- an application for calculations above 2^64 may be released.

Thank you for helping us!


Sincerely,
Project team.

Где вы взяли такое написание?

Правильное написание здесь
https://boinc.tbrada.eu/show_user.php?userid=1
Tomáš Brada

Даже по-английски имя Tomas не пишется, как вы написали, а пишется именно Tomas.
Например, один из моих адресатов из США: Tomas Sirgedas.

Заявка вам уже поступила.
Почему не запускаете второе Приложение?
Если код SerVal неправильный (как вы утверждаете, несёт опасность кранчерам), напишите свой - правильный.
Что мешает?

В результате в проекте гонится рутинный брутфорс, программа которого была написана 9 лет назад Алексеем Белышевым.
А между тем, люди бьются над поиском 19-ки с минимальным диаметром (и я, и Петухов, и его коллеги на форуме dxdy.ru).
