1) Message boards : ATLAS application : Trying to get ATLAS native working on Arch Linux (Message 34870) Posted 3 Apr 2018 by Bas Post: I tried to change the first line from "#!/usr/bin/env python" to "#!/usr/bin/env python2", but that didn't work: I got the same error, and when I checked the script again, the first line was back to "#!/usr/bin/env python". Thanks for help, but I'll keep crunching non-atlas tasks for the time being.
2) Message boards : ATLAS application : Trying to get ATLAS native working on Arch Linux (Message 34853) Posted 2 Apr 2018 by Bas Post: After some internet research, I have come to the conclusion that in a box with both python2 and python3, it is the script maintainer's responsibility to choose the right version. Victor has it exactly right. That means I still won't run atlas task unfortunately, not native, and not in vbox. The devs have to fix this.
3) Message boards : ATLAS application : Trying to get ATLAS native working on Arch Linux (Message 34852) Posted 2 Apr 2018 by Bas Post: Installing python2 didn't help, I get the same error. I'm thinking I should make python2 the default python version, but only for the boinc user. I'll be back...
4) Message boards : ATLAS application : Trying to get ATLAS native working on Arch Linux (Message 34851) Posted 2 Apr 2018 by Bas Post: @gyllic: I didn't have python2 installed. I have now, but the default is python 3.6.4 (output of python --version). I don't know how to change it to python2, and I'm not sure if I want to. It may break something... Anyway, I'll try to get another native atlas task and post the result here. @computezrmle: "run test applications" does not have any effect as far as I can tell. I'm always getting native_mt tasks unless I deselect "ATLAS Simulation" altogether.

6) Message boards : ATLAS application : Trying to get ATLAS native working on Arch Linux (Message 34847) Posted 2 Apr 2018 by Bas Post: I am trying to get ATLAS native_mt working on a Arch Linux box. I have successfully installed cvmfs (2.3.5-5) and singularity-container (2.4.5-1) from the Arch User Repository, but unfortunately the task ends after a few seconds with a computation error: https://lhcathome.cern.ch/lhcathome/result.php?resultid=186423033 This is a python error, right? So it looks like the "commands module" is missing on my system, but i have trouble finding the right package to install. If I search for "commands" or "subprocess" (python.org says the commands module is deprecated, and you should use the subprocess module) in the Arch Linux and Arch User repos, there are a couple of packages that might do the trick: python-sh python-ptyprocess python-whelk python-delegator python-easyprocess python-executor python-sarge python-subprocess2 python-subprocrunner And while I was creating this post, another task ended with a computation error, and now we know that "python-ptyprocess" is not the package I need... Although I can run ATLAS tasks with vbox, I don't do ATLAS because I keep getting the native task as well, which is really annoying. So it would be great if someone with more python knowledge than me (mine is zero) can help, or if there was an option to choose between "native" and "vbox" in the preferences.
7) Message boards : Number crunching : port 8884 udp (Message 34696) Posted 18 Mar 2018 by Bas Post: On my firewall, I see a lot of UDP packets going out to port 8884. This port isn't mentioned in the FAQ. Should I open my firewall for these packets?
8) Message boards : Number crunching : ATI GPU option while FAQ says GPU's are not supported (Message 34597) Posted 12 Mar 2018 by Bas Post: Ok, thanks.
9) Message boards : Number crunching : ATI GPU option while FAQ says GPU's are not supported (Message 34595) Posted 12 Mar 2018 by Bas Post: There is an option in the LHC@home preferences called "Use ATI GPU". The FAQ says GPU's are not supported. Does the "Use ATI GPU" option do anything?
10) Questions and Answers : Unix/Linux : arch linux virtual box (Message 34585) Posted 11 Mar 2018 by Bas Post: I got vbox working with the help of yeti's checklist and the Arch Linux VirtualBox documentation, thanks everyone! I'll check the threads discussion, at the moment the Atlas task is only using 1 of 8 available threads... oh wait here we go 780% CPU that's more like it.
11) Questions and Answers : Unix/Linux : arch linux virtual box (Message 34575) Posted 10 Mar 2018 by Bas Post: Your logs show that you ran only Sixtrack and ATLAS (native). Both don't need VirtualBox. I'm sure those atlas tasks only showed up after I installed virtualbox. But then again, the logs said that virtualbox wasn't installed... Maybe I'll try again tomorrow, maybe not.
12) Questions and Answers : Unix/Linux : arch linux virtual box (Message 34574) Posted 10 Mar 2018 by Bas Post: Boinc thinks virtualbox isn't installed: cat /var/lib/boinc/stdoutdae.txt \| grep -i virtual 10-Mar-2018 21:30:29 [LHC@home] VirtualBox is not installed
13) Questions and Answers : Unix/Linux : arch linux virtual box (Message 34573) Posted 10 Mar 2018 by Bas Post: Ok thanks, Yeti's checklist said something about extensions, so now I installed these: libvncserver-0.9.11-2 virtualbox-5.2.8-1 virtualbox-ext-vnc-5.2.8-1 virtualbox-host-modules-arch-5.2.8-3 I'll let you know how it goes...
14) Questions and Answers : Unix/Linux : arch linux virtual box (Message 34571) Posted 10 Mar 2018 by Bas Post: I'm sure it will run on my Arch boxes, but it seems there is some configuration necessary. Maybe it has to do with permissions I don't now. But unless someone is going to spoon-feed this to me, I'm pointing my processors somewhere else.
