1) Message boards : Number crunching : certificate
Message 57252 Posted 29 Oct 2017 by kay |
Hi, thank you for your prompt reaction. My credit is fine again. However, the certificate still doesn't work for me. In https://www.cpdn.org/cpdnboinc/cert1.php both https://www.cpdn.org/cpdnboinc/img/myles_signature.png and https://www.cpdn.org/cpdnboinc/img/OxfordLogo.gif are reported as "404:Not Found" to me even when I try to directly access them (and thus do not appear in the resulting page of the PHP script, too). I'm using Firefox 56. Regards Kay |
2) Message boards : Number crunching : certificate
Message 57192 Posted 26 Oct 2017 by kay |
Hi, I wrote a message to one of the administrators of the board some weeks ago because I could not create a certificate anymore (dead picture links in the PHP scripts). Which should be a very easy issue to solve. I got now reaction, instead now all my credit is gone (the certificate script is still missing the pictures and my credit is now given as 0). Can someone please look into this? I have donated a considerable amount of personal effort, coumputation time and electric power (= money). |
3) Questions and Answers : Unix/Linux : Safe shutdown
Message 54638 Posted 15 Aug 2016 by kay |
Thank you for your answers. Although I shut the machines down in the way I explained I just had another 4 tasks throwing erros instantly on restart - all with Error code 193. For me this is unacceptable and I also do not want to run only one task per machine, as they are all capable of running 2 or 4 simultaneously. I would rather stop the project at all to save the energy, as sad it would be (for me). Isn't there any manual which explains the behavior of the executables? I watched htop when suspending the tasks, they disappeared instantly, so I don't know where to start, as I first expected them to sustain for a bit until they have written everything to the harddisk, which might take a while. I would then have tried to subsitute the regular shutdown routine with a custom script that would first wait for all the boinc tasks to have disappeared and then continue with the actual shutdown, as I thought they might recieve a SIGABRT or something when they do not disappear a certain time after the OS has send a SIGTERM when doing shutdown and then would have not completely written everything to harddisk.
If so, I think they should not be send out for boinc at all. Regardless that it shouldn't be too hard to make the executables more stable for example by ensuring everything written into files is marked as complete when done and if a file is read and there are uncomplete sections, to just throw them out and recalculate (assuming sequential writing). |
4) Questions and Answers : Unix/Linux : Safe shutdown
Message 54635 Posted 11 Aug 2016 by kay |
Hi, I'm running climateprediction.net on multiple machines now, most of them doing nothing else, all linux machines. They are usually running 24/7, but since they are in my room sometimes I shut them down at night when it's too noisy. I do this by remotely logging in into every of them, pausing the project in boinc, waiting for several minutes and then shut them down to prevent erros. Anyway I recently had almost all task crash after a restart, many of them running for over a million seconds now - considerable amount of energy/money investment here - just gone! So what I'd like to know: is there a -completely- safe way of shutting down a system without risking to crash everything? I even watched the hdd i/o sometimes. If it would involve manually starting the WUs without boinc and manually shut them down (both with scripts or something), that would be okay too. Is there a manual on this? Kind regards, Kay |
