Today we are releasing a new app (in beta for the moment) to help analyze Planck data. Read more about it in the comments. Start crunching this app now for a chance to receive thanks in the acknowledgements of our forthcoming paper! |

Part of the promise of all the updates, Virtualbox, the boinc2docker jobs, etc... was to make it easier for us to deploy apps, so we could go from "cool science idea" to "functioning Cosmology@Home app" quickly and make the results that you guys are calculating as relevant as possible for science going on at this very moment. Today this starts to become reality as we are releasing a new app called "planck_param_sim". We will give more details in a post when it comes out of beta (hopefully very soon). For now though a brief summary,

Thanks, and don't hesitate to give us any feedback below! First task - validate error http://www.cosmologyathome.org/result.php?resultid=36244200 |

Thanks, and don't hesitate to give us any feedback below! Issue should be fixed now. I'll go back and revalidate your first couple of jobs that I see were marked invalid. |

Issue should be fixed now. I'll go back and revalidate your first couple of jobs that I see were marked invalid. I returned 3 tasks so far. 2 were invalid and 1 was valid. This valid one turned into invalid too now. I'll hold back the 'In Progress' tasks waiting for a better fix. |

I returned 3 tasks so far. 2 were invalid and 1 was valid. Ooh that's fast. Now all three invalids turned to Completed and validated. I'll start another task. |

Could you mention the approximate amount of memory this new app requires, relative to the previous app, so users who have had to set No new tasks due to the memory demands of the previous app can decide whether to enable ONLY the new app? |

How can I get the new Jobs? It only gives me boinc2docker jobs when I update. |

Thanks, yea, this is currently listed as having the same memory requirement as camb_boinc2docker, which is 2GB. I left it the same not realizing anyone was holding back due to memory requirements. But in truth it only uses between 500-1000 MB, so I will go ahead and lower it. |

Hi and thanks for the reply. Got some jobs now and wanted to run them but after a minute or so it just ends with a computation error. You need any info for troubleshooting? http://www.cosmologyathome.org/result.php?resultid=36258867 |

You need any info for troubleshooting? http://www.cosmologyathome.org/result.php?resultid=36258867 Yea, you're not the only one, I'm seeing an unusually high number of these "run for ~1min, computation error" jobs from everyone. Maybe like 1/3 of them. For some people it seems to just work after a while, for others it never does. Yours for example give back no log, which is extra confusing. For others it looks to be related to failures pulling the Docker images from inside the job. Looking into it... |

Alright. After removing the project and adding it again I managed to get past a minute without any errors but then after ten minutes I got this error: http://i.imgur.com/n3TUtjA.png What also makes me wonder is why my CPU usage is always at 0% or 1% but the status on the projekt is "Running" and the progressbar is also filling. Let me know if you need any further information. |

Ah, for that error there's some discussion in this thread this thread. Downgrading to Virtualbox 4.X might be a solution. Otherwise we actually also just made an update aimed at giving us better logs to figuring out what this error is, so I'll be curious to look at yours from this job. |

I tried the latest VBox installation and now CPU usage is actually back at 100% if I start a task, thats good. I'll let it run for half an hour now and report back if I run into any errors. |

Validate errors still are happening. I have noticed that two results are being generated for each planck_param_sims (beta test) work unit. I also noticed that when the second result is computed and then reported, it always is a validate error (possibly unless the first result is declared invalid). A possible stopgap solution could be to program either the work unit generator or the result generator to generate only one result per work unit. The long term solution would be to program the validator to be able to validate all non-tardy results despite the fact that some other result was reported first and tardy results that are reported before their replacement work units are reported. |

All tasks fail on my Linux box with "process exited with code 1" This suggests some library problem I think. I'll try on OSX later. S. |

All tasks fail on my Linux box with "process exited with code 1" Thanks, yea there's a ton of these errors unfortunately and I'm digging into it. Definitely not a library thing though, these jobs are running inside Docker inside a VM so they don't interact in any way with what you actually have installed on your machine. The calculation is getting killed by SIGILL, I'm working on getting the right logs out of jobs to figure out what's going on. Validate errors still are happening Yea, a few of these sorry about that. I will go back and re-validate them. You pretty much debugged the problem on our end exactly. |

Well, looks like I don't get the new app working on one of my hosts - an AMD Phenom II X6 1045 with Windows Vista. Installed is BOINC 7.6.22 and VirtualBox 5.0.14 now. I tried different VB-versions from 4.3.20 up to the one now, but it doesn't look as if it can work correctly - CPU is seemingly using only one core when I look into the task manager and the percentage won't go over 0,1%, already running over an hour now. I cannot test it on my other machine (AMD FX 8320 with Win 7) currently, BOINC manager says there are no tasks available, yet the server status says something else... ?

Did you try to remove the C@H Project in your Manager and then readding it, only allowing Plank tasks? That fixed it for me, my Xeon was crunching numbers all night, maybe Marius can check some of my tasks if they are really valid. They finished without error in ~6 minutes. Cheers |
