What is ODLK1?

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:

New K-Tuple competition
With the new year we organized a new K-Tuple competition:


The competition will last 3 months and is for finding new result about some k-tuple open problems (there are 7 tasks).

Unless this Boinc project were all contribute to find solutions in latin squares field donating CPU power, the competition is for people that like to code programs and experiment with mathematics to find new solution by them-self.

For this project instead, the DB with all the solutions will be available as soon as November and December months will be finished to being processed for dividing the solution by their ranks.

Server problems

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).

from tomorrow I will be on holiday for max 15 days without server access, so be sure to add a backup Boinc project in case of server problem.
