2020-06-19: Badges

New badges for the SPT sub-project! The Prime Tuples subproject fully covered the missing range from Stop@Home and also scanned for new kind of tuples (tpt, stpt, gaps) up to the same range. As a Thank You to all contributors, I present you four new badges. The badges are awarded based on credit earned on the SPT app (ids 10,11), not RAC and the credit level have been chosen based on current credit distribution. The results of the project are slowly being submitted to OEIS. If you do not have a badge, do not worry, there will be more tasks, searching for rarer and longer sequences.

2020-04-24: Plan for SPT subproject

For processing of SPT results I found a partner that will help me write a export script to OEIS, and he is working... And while he is working I forgot a bit that I have a project, sorry. I was excited to have my name in OEIS, but it is not yet ready and the excitement is fading.
The previous batch, using the new file upload handler ran out, and it is much smoother. I submitted new batch 70 that goes up to 5e17. See, this new SSD and FUH allows me to have larger batches. And after that, I will submit batch for 5e17-6e17. You might notice that we already did that range, but that was with old version, which only looked for symmetric prime tuples and was slower.
Regarding the padls total (tot5) subproject, it is still running, but I throttled it to only few active tasks to not waste power. There are some ideas to improve it.
However, I am working on the Lua / compile-on-target application.
Have a Great day everybody and stop pretending and blocking yourself.

2020-03-15: CoVid19 Reduction in tot5 compute work

Because of the global situation, I am disabling distribution of new PADLS tot5 workunits in an attempt to divert the compute attention to Folding@Home.
Happy spring Equinox!

2020-01-30: Database Crash and Recovery

03.03.2020: Somewhere around 20.02.2020 another database crash occurred. This time we did not loose any data (all was backed up). After a disk swap, most of the functionality has been restored. I am still slowly working on restoring the science result database and work generator.

30.01.2020: Unfortunately, the database here suffered a corruption and crashed. Fortunately, the backup was less than 24 hours old, so we did not loose much. I am attempting to recover recent results that are lost in database from uploaded files. While this process is running, scheduler will be disabled and you may see strange numbers in the server status page. After that process is complete, you will have time to upload results in progress. The results that are definitely lost will be resent.
No other results were lost.

2019-12-13: Downtime

We should be back online!
I apologize for the downtime. It was caused by unexpected network connection failure. The failure was outside my scope of influence. I was only able to set up a error page on Endora with link to our partner's forum.

The tasks that timeouted during the downtime will be resurrected and the deadline extended by a week. The unsent duplicates will be aborted. Only then sheduler, donwload and upload operation will be resumed.

2019-11-04: Windows app for Symmetric Prime Tuples

An application for Windows was recently enabled to search for Symmetric Prime Tuples!
I submitted a bunch of new tasks for this application, which already yelded a interesting soution. Application for linux is also available, but that is old news.
I promise there will be subproject badges, but I won't say when.

2019-10-18: Symmetric Prime Tuples test

After multiple closed tests, I am happy to announce new Subproject!
The search for Symmetric Prime Tuples is a continuation of deceased project Stop@home.
The application is now available as beta for Linux and will be available for windows tomorrow.

Please report any issues here.

2019-09-19: Downtime

Sorry for the downtime. Compiling mysql took longer than anticipated.
Not only that, But I also messed up the server so it took some time to recover.
And even more issues caused unavailability till I could get physical access.
Note: the even is now over.

2019-09-16: PADLS TOTAL rule 51 experiment results

Over three months, more than 700,000 unique CFs ODLS were found in the project, including 5 rare groups of ODLS pairs (three and four)

Grand congratulations!

Many thanks to all the project participants!

2019-09-05: Badges

This project has badges now!
They are based on total credit, but I did not want to be usual, so I choose thematic thresholds.

Lv. 8) Over 6204 credits.
Lv. 9) 37224
Lv.10) 197600
Lv.11) 785997
Lv.12) 2629687
Lv.13) 6873318
Lv.15) 16350666
Lv.17) 84584914
The "numbers" are number of SNDLS on the corresponding level of rule 51. The badges are assigned to Users and Teams alike and next level badge replaces the previous level.
Also the credit gain has been increased about 30% up.

2019-07-25: Padls Total subproject running fine

Better late than never. The PADLS Total experiment described in this thread is running fine on this server and is producing good results.

More details in Subproject Description.

A effort was initiated to install the subproject over at Ice00's server server.

2019-06-18: Testing Padls Total

Experiment with name Padls Total now entered testing phase.
A new application was developed for this project which is currently available as a beta for Linux. This application finally supports checkpoints. Please, decide if you really want to participate in the beta work. The work generator is also being tested, so there are many tasks available and if you have beta work enabled, you may get way too much.

If you enable beta applications, be prepared to have:
* tasks suddenly aborted by server
* your completed tasks not validated for weeks
* no credit assigned for weeks
* tasks crash or get stuck running
* no apps for our favorite platform
* strict deadlines
* wrong run-time estimate

This is batch 15, 21 and 22 on the server_status page.

Another remark: it is not necessary to run the beta work continuously. Run it for a while and then disable it. Leave some to me to test. Credit allocation, windows application, automated result publication and deadline adjustments will all be done before the application leaves beta mode.

The server might not be available all the time as I am trying different storage solution.

Programming talk and development updates are in this thread.

2019-05-14: PADLS TBtest batch 14

Happy May!
I created new program and I want to test a idea that ODLS can be found directly in the output of the generators without first permuting them. This program checks dls about 40 times faster, but not as thoroughly. The same space is checked as batch 10, 12 and 13. Additionally the maximum number of diagonal transversals is recorded.
The workunit name is as follows:
padls4_a61923754 - application name
padls4_a61923754 - application compatibility version
padls4_a61923754 - generator version (a or b)
padls4_a61923754 - 8 numbers forming a input row for the padls generators

Credit will not be awarded during validation, but later during assimilation of the batch. Credit will be granted based on the number of Latin squares checked. If you do not agree with the experiment, the credit or the fact that your data is stored on my SD-Card, then please do not participate.
