Czy można prosić admina o informowanie o aktualnych/przyszłych próbach rozruchu projektu? Wiele zadań jest przeliczanych po kilkanaście godzin i kończą się błędami. Paczki zadań są usuwane z serwera bez wcześniejszego informowania. Czy powinniśmy wtedy anulować zadania aby nie grzać procesorów bez potrzeby? Mam wrażenie, że ten projekt jest nadal w fazie testowej. Jeśli tak jest to proszę to wyraźnie podkreślić na stronie głównej lub włączyć w ustawieniach projektu możliwość pobierania normalnych lub testowych zadań. Trzymam kciuki za dalszy rozwój projektu, bardzo chętnie będę przeliczał zadania.

Could admin give us information on recent and future actions taken on the server? Many tasks are being calculated more than 15 hours ending with errors. Series of tasks disappearing from server. Should we then cancel tasks manually? It seems to me that this project is still in testing stage. If so, there should be a notice on main page or it should be possible to choose whether we want to download normal tasks or test tasks. I hope this project will develop well. Waiting to crunch more.

Dzieki a post,
Probujemy wykorzystac platforme do badan wymagajacych wysokiej precyzji obliczen.
Niestety okazuje sie, ze jest to niezwykle trudne wyzwanie dla platformy boinc :(
Zroznicowanie procesorow (mocy obliczeniowych) bardzo wplywa na czas obliczen numerycznych w zagadnieniu calkowania ruchu w rownaniach rozniczkowych.
Nie mozemy przewidzec jaki bedzie czas obliczen poszczegonyc zadan ( nie biorac pod uwage wydajnosci procesora).
Z drugij strony nie chcemy ograniczac dostepu tylko dla komputerow o wysokiej wydajnosci obliczeniowej ...
W ostatniej wersji obliczen przez 24 h mielismy 99% skutecznosci, niestety pozniej ilosc proceow z bardzo dlugimi czasami drastycznie wzrosla.
Staram sie w chwili zaistnienia problemu wywolywac przerwanie obliczen przez serwer w celu ochrony czasu obliczen na Panstwa procesorach.
W tej chwili opracowuje wersje programu ktorej piorytetem bedzie ochrona czasu obliczen ( zadanie zakonczone po okreslonym czasie ok 2h).
Niestety zmusza nas to do wylaczenia procesu walidacji obliczen zwiazku z roznicowaniem ilosci otrzymywanych wynikow( liczy krokow calkowania od wydajnosci procesorow).
Mam nadzieje ze znajdziemy rozwiazanie , ktore bedzie spelnialo wasze i nasze oczekiwania.
Prosze o jeszcze chwile cierpliwosci....

Dziękuję za odpowiedź. Myślę, że warto ją przetłumaczyć na język angielski, choćby z grubsza. Zagraniczni cruncherzy również liczą na lepszą komunikację z adminami. Dobrze przeczytać od czasu do czasu na czym stoimy, w tym lub nowym wątku.

With a wide range of computational complexity and client performance, the BOINC platform has several tools

The simplest solution is to create several variants of the application with tasks of different sizes - S, M, L, XXXL. And provide app selection to users (enable advanced preference settings). It will be easier to validate tasks of the same size with each other than comparing different-sized tasks (terminated after 2 hours)

You can assign conditional complexity to such tasks of different sizes and set criteria for the scheduler of the allocation task by processor type. Here you need to know well the processor models and their performance on your tasks. Additional load on the server and on the admin when creating and distributing tasks.

You can also use processor optimization (instruction sets SSE2 - AVX512) when compiling multiple versions of the same application. Distribute tasks of different sizes across several plan-classes with the requirement of the desired option from the CPU. If your algorithms allow - enable multithreading. There are volunteers who can speed up your applications several times. This has already happened on other projects

Dobrze przeczytać od czasu do czasu na czym stoimy, w tym lub nowym wątku.

For global problems of the project and directions of search, the "science" section is well suited. opening a discussion on an important topic you can always get a hint

For operational actions with the project, you can post a short message in the "news" section with the option to notify clients - for example, about canceling tasks on the server and the need to clear the client's queue.

Such communication will reassure the participants - people have found a new project and expect stability as a project in the production stage, and not as test launches ;o)

What are you plans and time lines (goals) for releasing applications for other hardware / operating systems ?

Microsoft Windows running on an AMD x86_64 or Intel EM64T CPU

Thanks you

(maybe if the compilation for windows is difficult, they can use boinc wrapper...)

I'm wrong.
The next step is checkpoints!! :-P

I remember ....
We are adopting versions to the new DR3 Gaia catalog now.

We will use boinc wrapper in near future

Is the code open? Maybe volunteers can help..

I'm very interested because it doesn't work on windows systems.
I have to ask the owner of the code.
I hope that in private correspondence We can provide the code with a request not to distribute.

When will you implement checkpointing???
Over 4 hours per WU with no checkpointing. I'd do a lot more work for you if you had checkpointing.

Until you learn how to implement checkpointing you could add the pulldown option in Preferences to only download 1,2,3,4,5,6,7,8 or unlimited.
