server outage / db crash again - 3rd  |
Every day a new repairing day. Today the power supply died on 12V, tested all components and was lucky to have a second one replaced.
Fortunately I could rescue the hole database but took some time to import (8GB). Nothing should be lost.
Maybe there are some results lost but didnt care. Will be rerun later.
If you find some errors somewhere let me know.

| server outage / db crash again - 2nd |
Due a win10 issue identified now, the VSS service which has restarted the PC automatically and in hope that is fixed with a MS solution found in the web the database crashed before I could do a backup. As always a good timing and sadly lost around 13h of work (results which were already done are not affected).
You will get a lot of download errors but can be ignored while they were already processed.
As always let me know how many credits you have lost and post it in the other thread.
All latest win10 updates were also installed.
Iam very sad about the current situation, it was not the first time related all biggest theads to the new OS.

| DB CF ODLS of order 11 |
Я официально открываю новый проект DB CF ODLS of order 11.
Некоторые исследования по этому проекту уже выполнены в теме "ОДЛК для порядков n>10"
https://boinc.progger.info/odlk/forum_thread.php?id=162
Мне помогал в исследованиях Tomáš Brada.
Смотрите тему "Diagonal Latin squares of order n>10"
https://boinc.tbrada.eu/forum_thread.php?id=3104
Проект имеет хорошее ПО, которое создано Белышевым и Harry White.
На данный момент я имею небольшое ядро БД, содержащее 28578 КФ ОДЛК.
Приглашаю всех присоединиться к проекту.
Рассмотрю ваши предложения по запуску проекта на платформе BOINC.

| Server problems this past weekend |
We had what we thought was a hard drive crash - the drive went into a read-only state and the server crashed. It would not even allow a remote reboot. We finally got someone in there this morning to do a hard shutdown.
The system came back and appears to be working now. But we will continue to keep an eye on it.
If you are like me, you will have a bunch of WUs that need uploading. Please have patience as everyone will be uploading at the same time, so there might be delays.

| No GPU work for some hosts |
Yesterday I have added some new plan_class changes in the plan_class_spec.xml
There was a driver limit for different cuda versions. Now some users reported me some specs and the driver version overlapped with upcoming new cuda11 apps while they havent get any new work. Thats bad because old cards cannot running the new cuda11 apps. I need to find out another way which hosts can run which app.
The limitation was removed so all should be fixed now.
If you have still some issues let me know.

| New and improved apps coming soon |
I have made some improvements to the cpu code. I am seeing somewhere between 30% and 40% speedup, depending on the case.
I have deployed the new executable for 64bit linux. I am currently trying to get it to build for 64bit windows. I hope to have that ready by tomorrow sometime.
The next step is to use these same tricks on the GPU versions. GPUs can be very finicky, so this might take several weeks before I have something worthwhile.

| Server shutdown for maintenance / Parada del servidor por mantenimiento |
Dear volunteers,
After a long time in which the project has not been maintained 100% of the time, the server and BOINC version have become obsolete. Applying all the necessary updates is often problematic and in fact BOINC does not automatically update well in DENIS. That is why, in collaboration with the University's IT department, we have made a backup of everything and we are going to carry out a clean installation of the server and BOINC to restore the project on it. It is not a simple operation and we are going to do it calmly.
That is why from tomorrow or Monday the server will not be available. As soon as everything is restored we will notify you again here.
The current situation due to the pandemic has not left us much time, but this whole update comes because we have a new project in which we want to use DENIS and that you can continue to collaborate with science.
Thank you all for your patience.
Greetings,
Jesus.

Estimados voluntarios:
Después de mucho tiempo en el que el proyecto no ha estado mantenido el 100% del tiempo, la versión del servidor y de BOINC se han ido quedando obsoletas. El aplicar todas las actualizaciones necesarias suele dar problemas y de hecho BOINC no actualiza automáticamente bien. Es por ello que, en colaboración con el departamento de Informática de la Universidad hemos hecho una copia de seguridad de todo y vamos a realizar una instalación limpia del servidor y de BOINC para restaurar sobre ella el proyecto. No es una operación sencilla y vamos a ir haciéndola con calma.
Es por ello que desde mañana o el lunes el servidor no estará disponible. En cuanto esté todo restaurado volveremos a avisar por aquí.
La actual situación por la pandemia no nos ha dejado mucho tiempo, pero toda esta actualización viene porque tenemos un nuevo proyecto en el que queremos utilizar DENIS y que podáis seguir colaborando con la ciencia.
Muchas gracias a todos por vuestra paciencia.
Un saludo,
Jesús.
