Theory vbox and Theory native have different requirements Theory vbox client OS: either windows or linux VirtualBox: must be available and activated CVMFS client: doesn't care Theory native client OS: must be linux (there's no CVMFS client for windows) VirtualBox: doesn't care CVMFS client: must be available While the BOINC client can tell the server which OS is installed and whether VirtualBox can be used it has no option to tell the server anything about CVMFS. Plan classes are a method to offer different app versions under the same app id but the decision which app should be send is made on the server. Their main objective is to find out which app version runs fastest on a given client and automatically prefer that app. This doesn't mean that the server completely stops sending tasks for another app version. Instead it will regularly send others to get benchmark results. The idea to fake benchmark results on the client using app_config.xml will not work as <flops> isn't a valid option inside app_config.xml and will simply be ignored: https://boinc.berkeley.edu/wiki/Client_configuration The only setting that can be made client side is whether VirtualBox is on or off but it has already been stated that this affects all projects running on the same client. ATLAS uses a weird method to "misuse" the server side beta app flag in combination with the VirtualBox flag but as already stated this is a global setting per venue and affects other subprojects (SixTrack beta) running on the same server/venue. A workaround to define separate venues and to run extra clients concurrently is limited by the fact that the standard server doesn't allow more than 4 venues. Long term (reactivating LHCb?, introducing ALICE?) the best solution would be to allow more venues (see primegrid) and to introduce individual preferences per subproject (see einstein). |

Tiny correction: “Theory vbox client OS: either windows or linux†...or Mac Many thanks computzrmle for your great knowledge and faithful support of LHC@home! Ben |

Or the way WCG does it.and to introduce individual preferences per subproject (see einstein).I agree with that. |

I only have 1 Linux host which is now getting a mixture of Theory Native 1.01 (native_theory) and Theory Simulation 300.02 (native_theory). The other 2 hosts are Win10 so can only run vbox tasks. I don't watch them all but it can be useful for ones that look as if they may be running too long to be able to look inside to check whether all is well or to intercept a Sherpa that wants to run for 6000 days. With vbox tasks all that is required is a simple click on Show Console but with native tasks one has to check which slot it's using, wade through directories, putting in password twice along the way to get to the logs or use a Terminal to get there using comutezrmle's command line I know which option is easier for me and would like to be able to choose to retain that option through a tick-box in Preferences rather than having to resort to app_configs or other potentially overcomplications. |

ATLAS uses a weird method to "misuse" the server side beta app flag in combination with the VirtualBox flag but as already stated this is a global setting per venue and affects other sub-projects (SixTrack beta) running on the same server/venue. I will investigate using a run native option in the project preferences. |

There is a new option in the project preferences Run native if available?. It is not quite working as expected. |

There is a new option in the project preferences Run native if available?. It is not quite working as expected. What does if available mean? If Theory is checked - run Theory native app instead of Theory vbox (even if vbox sofware is installed)? - run Theory native app beside Theory vbox (if vbox software is installed)? If checked, does it send Theory native to windows hosts? Can a linux host (temporarily) be blocked/banned if N consecutive tasks fail due to a CVMFS error. N should be much smaller than the usual 500 tasks that are allowed to fail per day. Same for ATLAS? |

I have Unchecked the Run Native box and that host didn't request Native although I won't know if it will request vbox tasks instead until current cache runs dry (2 running, 1 queued), however, the "If no work for selected applications is available, accept work from other applications?" box is checked. Editing the prefs shows it Unchecked but on Update to save refs, it reverts to Checked so I'm unsure whether that setting has Set or not so it may still get Native if no vbox are available. |

Project-Server show for native more than 400 tasks available. But since 1:30 UTC get no more Downloads. |

native Theory (1.01) have work again, thank you. New -native Theory (300.02) is integrated to Applications for Theory. How can we control this? |

How can we control this? ok, I think it is working now. So if you want to run native you need to check the Run native if available? option in the project preferences. It should behavior as follows: Not checked, No VBox = No Tasks Not checked, VBox = VBox Tasks Checked, No VBox = Native Tasks Checked, VBox = Native Tasks Note: That is is only for Linux and does not affect any other platform. If this works fine, we can make this work with ATLAS. |

Yes, there is a check_punitive option in the validator. We check for error strings and reduce the maximum number of jobs per day to 1 if there is a systematic error such as not having CVMFS installed.
We can do the same fro ATLAS once everything have been confirmed to work for Theory. |

FTM we get native Theory(1.01). Is this so long there is work available? Or need we a Wipecache, Reboot of the Linux or Reset of the project in Boinc to activate native Theory (300.02)? Is Test-Application in Preferences needed? native Atlas need it also. |

Linux host: Preference - Theory Simulation VBox installed - No Run test applications? - not checked Run native if available? - not checked ------------ I got no task Preference - Theory Simulation VBox installed - No Run test applications? - not checked Run native if available? - checked ------------ I got a Theory Simulation v300.02 (native_theory) |

No, the native app is out of beta, you just need to check the Run native if available? option. |

Linux host: Great! Looks like it is working as intended. |

Linux host: Preference - Theory Simulation VBox installed - Yes Run test applications? - checked Run native if available? - not checked ------------ I got Theory Sim 300.02 (vbox64_theory) as requested 8¬) So app selection looks to be working, however, I have set Max # jobs = 4 Max # cpus =1 I used to get up to 4 tasks, running 1 core each, on this 2-core host (which is the configuration which has always worked well on it) but today I only get 1 task at a time, (event log says No tasks available) leaving the other core idle. |
