BOINC-project ODLK1 continues to solve the problem of BOINC-project ODLK.
The project generates a database of canonical forms (CF) of diagonal Latin squares (DLS) of order 10 having orthogonal diagonal Latin squares (ODLS).
The necessary definitions for the theme can be found here:
DB CF ODLS of order 11
I am officially opening a new project DB CF ODLS of order 11.
Some research on this project has already been done in the topic "ODLS of orders n>10"
Working theme created
Tomáš Brada helped me in my research.
See the topic "Diagonal Latin squares of order n>10"
The project has good software, which was created by Belyshev and Harry White.
At the moment I have a small database core containing 109025 CF ODLS.
I invite everyone to join the project.
I will consider your suggestions for launching a project on the BOINC platform.

DB CF ODLS of order 9
I am officially opening a new project "DB CF ODLS of order 9" .
This is not a BOINC project yet, but a manual project. I have been working on a project for a long time on a PC.
But you can turn a manual project into a BOINC project if you want.
Here you will find the software you need
(small archive, 2.1 MB)
The software was created by Belyshev and Harry White.
This is the script that works for me
@echo off DLS9R1BdFdCP.exe copy TemporaryDLS9R1BdFd.txt input.txt kanonizator_dlk9.exe < vvod1.txt copy output.txt input.txt ortogon_u.exe < Y.txt copy /b rez.txt+mates.txt rez.txt pause
I'll be on holiday for 10/12 days from tomorrow without access to the server.
I hope that all goes fine as in the last months.

As Linux is almost perfect if you get the same problem two times in short time, that means that there is an hardware problem behind!
The first time I can think it was due to the 3 working people that add new devices in my network for having three more connection speed of actual one as they manage to add cables and move devices during the operation.. and after them you got a DB related problem into the server just 5 minutes after they gone...
But after having rebuild the DB from scratch (without losing any data) and get the same error..then it is an hardware error (maybe related to the system disk that manifest some operation degradation that should not happen with his young life)
Actually the DB is now moved onto the ODLK1 Boinc disk and this should stay good until the new disk arrived and I can move system to it (maybe in 15 days).

The results of ODLK and ODLK1 projects as of January 1, 2019
At the moment our database contains 5714925 unique CFs ODLS.
All results are published.
Thank you very much for your work!
