1) Message boards : Number crunching : Very long job (Message 43682) Posted 22 Nov 2020 by Hans Micheelsen Post: I've checked. Everything is 64 bit. And is freshly rebuild. In fact I got the lastest kernel and virtualbox right today from Mageia project. hansmicheelsen@localhost ~]$ uname -a Linux localhost.localdomain 5.9.10-desktop-1.mga8 #1 SMP Sun Nov 22 13:48:56 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux [hansmicheelsen@localhost ~]$ rpm -qa \| grep virtualbox virtualbox-guest-additions-6.1.16-1.mga8 dkms-virtualbox-6.1.16-1.mga8 virtualbox-kernel-5.9.10-desktop-1.mga8-6.1.16-10.mga8 virtualbox-6.1.16-1.mga8 virtualbox-kernel-desktop-latest-6.1.16-10.mga8 [hansmicheelsen@localhost ~]$ rpm -qa \| grep boinc boinc-client-7.16.12-1.mga8 boinc-manager-7.16.12-1.mga8 Status: After 2 days of work done time remaining is 1 hour 3 minutes. And each second remaining takes 15 second to run. Geee, there is 3 days left before deadline. With 1 hour left to go I'm afraid I won't make it. I'll switch off Atlas projects for my boinc computing. It's waste of good CPU.
2) Message boards : Number crunching : Very long job (Message 43659) Posted 21 Nov 2020 by Hans Micheelsen Post: I activated the Atlas simulation in VBox but nothing happens with Alt+F1, Alt+F2 etc. I've even tried the virtual keyboard. No reactions. Also the same on the other LHC simulations I have running in Boinc which are Theory simulations. One clue might be that on the Atlas simulation the virtual screen says This kernel requires an x86-64 CPU, but only detected an i686 CPU. The processor is unsupported in CentOs 7. My Cpu's are Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz

Then you would be able to check the output from the VM consoles. In case of ATLAS console 2 has a more accurate timer based on the logs from the scientific app. Timers are influenced by the CPU throttle. Your CPU throttle is set to 50%. Vbox apps should be set to 100%. If it is necessary to limit CPU usage on your computer use other methods. BOINC provides a couple of them. Allright, I just thought the simulations would use the CPU performance measurement and the computation configuration in the forecast for remaining time. I deleted the very long task I had, configured to 100 % CPU use. But set to using 50 % of availabe CPU's. I hope thats more correct. And now I have an Atlas simulation, that started with 13 hours remaining. Now after 1 days of computing, it says 4 hours remaining. And each second in remaining time takes 5 seconds. Lets see how things develop ... The task is: https://lhcathome.cern.ch/lhcathome/result.php?resultid=289197986 And I have installed VBox Additions. How do I use it?

It started reporting 13 hours to complete and now it says 1:39 minutes to complete. Taking something like 5 minutes per second to complete. I'm getting a little bit frustrated. Will it ever complete the task? I understand that I don't get any credits for it? Deadline is overdue since yesterday. But is my computer power wasted? I hope you don't use the same kind of timers in the real project. Are you really sure at LHC that you can handle this project?
