Sorry, I forget to add the recently acquired domain name into re-captcha settings. I've added it now. The web-based account creation seem to be working. Thank you for reporting this issue!rebirther wrote: Due an issue with re-captcha you cant create an account by web.
I'm sorry, I do not speak German, but if I understand correctly you've got a driver crash error for integrated AMD GPU (Radeon HD 8400). I apologize for this. I've added the following warning on the website: "Some issues with integrated AMD GPUs have been reported. It is not recommended to use them for this project until these issues are resolved". Also, I've indicated that the project is on the alpha stage (now it should be clear).Buckey wrote:hm... das Projekt scheint noch im Alpha-Stadium zu sein.
Wenn man sich mit der Domain statt mit der IP anmeldet gibt es ne Fehlermeldung im Client.
Dann habe ich noch auf einem Notebook mit integrierter AMD-Grafik festgestellt, dass wenn ich dort eine Anwendung öffne die auf die Grafikhardware zugreift der AMD-Treiber abstürzt und die WU trotzdem weiterrechnet.
Bis dato habe ich aber noch herrausgefunden mit was die WU nach Absturz des Treibers berechnet wird, die CPU, Festplatte und Grafikkarte können es eigentlich nicht sein, da diese laut Openhardwaremonitor nicht oder kaum in Benutzung sind.
Auf dem AMD-Notebook sind die Berechnungen die fertiggestellt wurden als ungültig markiert. Ich denke es wird die zu schwache Grafikkarte sein.
Bei meinem 2.Rechner mit NVIDIA GTX 960 Grafik sind zirka 4 Prozent Ausschuß-WU´s bei.
Insgesamt scheint es bei dem Test-Prjekt noch nicht wirklich gut zu laufen. Die Betreiber schein laut Webseite aber anderer Meinung zu sein. Mal sehen wie sich das Projekt entwickelt und ob es nach kurzer Zeit wieder aufgibt, wie so viele vor diesem.
That's interesting. It appears, that some Nvidia GPUs indeed do the computation for this project faster compared with some AMD GPUs of the same (or better) theoretical performance. However, the difference is not that big. First of all, one need to compare different results for the same WU in details.Buckey wrote:So, ich habe mal ein paar WU´s auf meiner AMD RX480 laufen lassen. Die Laufzeit bei der AMD Karte ist nicht sehr optimal. Auf der AMD läuft eine WU zirka 1/3 langsamer als auf einer NVIDIA GTX960. Ist schon erstaunlich der Unterschied. :shok:

5 Jun 2017, 21:46:33 UTC Project restart in June
The maintenance is almost over. The new native BOINC apps are being tested in the local network now. We expect the project to be restarted at the end of next week. This will be preceded by server and storage upgrade. The work on the database is still in progress and will continue in parallel with the computations.
Also, the paper “XANSONS for COD: a new small BOINC project in crystallography” was accepted for presentation at the BOINC:FAST’2017 conference which is to be held in Petrozavodsk, Russia in August.
18 Jun 2017, 18:09:05 UTC Maintenance is over!
The project is restarted with new native BOINC apps and additional computational scenario.
Now the large WUs can be assigned only to the GPU and the small ones only to the CPU.
GPU apps do not require dedicated CPU core by default anymore. If you notice any performance issues caused by this, consider using custom app configuration. Place this file in the project's folder.
The apps of this project do not make checkpoints. If stopped, the task will be restarted from the beginning. The task execution time should not exceed 10 minutes for moderate PCs. However, some tasks may take longer to complete on low-end PCs. This is particularly true for low-end GPUs. If the execution time of tasks is unacceptably high for your GPU, consider disabling it in the "Preferences for this project" in your profile page.
The project is in beta-testing stage. Bugs are more than likely. However, all the results obtained during this stage will be included in the final database If no critical errors are found.
Thank you for participating!
Somit ist das Projekt beendet. In der Datenbank wird bei den Sequenzen aber auf die User verwiesen, welche diese berechnet haben. Ich gehe daher ganz stark davon aus, da das Projekt weiterhin online bleibt.That's all! You did it!
It remains only to wait for the tasks in progress. Thank you very much for participating! You helped create the database of simulated powder diffraction patterns: http://database.xansons4cod.com.
