Rosetta needs more disk space : how to purge existing Rosetta@Home data and tasks files ?
(Message 101170)
Posted 8 Apr 2021 by Brian Nixon Post: I think I had read that in theory, the project can make calls to receive past finished tasks' local data in some cases, and that's why they persist some of the data post-task completion. Did I imagine it or is that correct ?It’s possible such a mechanism exists, but I’m not familiar with it. In my recent observation, BOINC deletes all Rosetta task files as soon as the results are uploaded. It’s the shared applications and the large protein database (500 MB download that unzips to 960 MB) that persist between tasks and consume disk space. |

I dare say it was like that here in the early days, too? And that 15 years from now users will be moaning that the SiDock admins don’t talk to them any more… |

(Message 101155)
Posted 8 Apr 2021 by Brian Nixon Post: It’s not just you. Lots of people are reporting errors like this. It looks like the current batch of work units is bad. There’s nothing we can do other than keep letting them fail until somebody at Rosetta fixes or removes them, or switch to another project in the meantime. Don’t hold your breath waiting for anybody from the project team to read or react to your message here. |

Posted 6 Apr 2021 by Brian Nixon Post: Ignore the …_abinitio_1_abinitio_… tasks; lots of people are reporting problems with those. For the others, this is a clue that all is not well: couldn't start app: Input file rosetta_4.20_x86_64-pc-linux-gnu missing or invalid: file missingTry Reset project under Project commands (Simple view) or on the Projects tab (Advanced view). Not sure about the SiDock issue; try the forums over there. {EDIT, though we’re way off topic here} You’re missing some prerequisite system libraries (glibc-2.27) which are newer than your version of Linux. It might be possible to install those alongside your system glibc, or it might be easier to update the whole OS. SiDock uses much more modern software than Rosetta; I have the same problem that I can’t run it on the ancient version of Windows on my crunchers… |

Posted 6 Apr 2021 by Brian Nixon Post: If you are using BOINC Manager in simple view, and there’s a button bottom centre labelled Resume, click that. Or in advanced view, on the Activity menu, select either Run always or Run based on preferences. Note that there is currently very little work available on Rosetta@home, so even if you do get the project running, you might not receive any new tasks for a while. |

Problems and Technical Issues with Rosetta@home
(Message 101086)
Posted 5 Apr 2021 by Brian Nixon Post: Isn't there a board or site somewhere that explains what "they" are doing when changes occur in the project that affect the donors in significant ways?There is. You’re on it. But it seems that Rosetta@home has been so successful for so long that “they” no longer feel any need to come here. The supply of computing resources appears to be taken for granted. Researchers simply throw tasks over the wall; as far as we know they do something with the results afterwards. That a batch of work can get sent out configured in a way that cuts off a third of the project’s capacity, without anybody noticing or taking any corrective action even though the problem was instantly noticed and reported by participants, leaves it quite evident that nobody is actively monitoring this project. |

(Message 101084)
Posted 5 Apr 2021 by Brian Nixon Post: The question i have is how often does Rosetta updates automatically and requests new tasks?It’s not a fixed interval. While the client is busy with work, it will not contact the server until it needs more work or has results to report. When it asks for work and does not receive any, the client will back off for ever-increasing lengths of time – up to 1½ days – before asking again. This is to prevent hundreds of thousands of hungry hosts hammering a server that has no work to send out. Is there a possibility to tell Rosetta to update every 10mins or similar?Anything you can do in the GUI can be scripted, so the short answer is yes – but it will needlessly burden the server, and should not be necessary. My feeling is that managing Rosetta to use the computer close to 100% is a bit luck.At the moment there is an element of luck in whether you get work for Rosetta, because overall there is only a very small amount of work that needs doing, and because some of the work units can only be sent to machines with large amounts of RAM and disk space. If those happen to be all that is available at the moment a smaller machine contacts the server, that machine will get nothing, and back off. You can leave machines running unattended 24×7; many people here have been doing it successfully for years. But it is not reasonable to expect any single project to have 100% uptime, or to need work doing 100% of the time. That is why it is recommended to attach to more than one project. |

Windows :
Rosetta needs more disk space : how to purge existing Rosetta@Home data and tasks files ?
(Message 101078)
Posted 5 Apr 2021 by Brian Nixon Post: Is there an easy way to clear the old / obsolete task files for Rosetta without breaking the project or having to do a bunch of complicated tasks?Yes: Reset project under Project commands (Simple view) or on the Projects tab (Advanced view). However: resetting will probably not make any difference, because Rosetta@home needs about 1.6 GB for its applications and data files in any event, and the current batch of work units is (mis-)configured to require 8.5 GB of disk space. So even if you get some tasks initially (which is itself not guaranteed, as there is a shortage of available work at the moment), they will consume 1.6 GB of your 10 GB limit, which will prevent the sending of any further tasks that also (claim to) need 8.5 GB. Here is a post from a user who reset recently, only to see the disk space warning come back shortly afterwards. Other users have reported that the tasks do not in fact require anywhere near 8.5 GB, so you could try increasing the limit to be able to download some tasks without much risk of Rosetta actually using much more than it currently is. |

Posted 4 Apr 2021 by Brian Nixon Post: I am told I am running two programs at once, and that I have to get rid of rosetta@home.Are you seeing the message You are attached to this project twice. Please remove projects named Rosetta@home, then add https://boinc.bakerlab.org/rosetta/ If so: in BOINC Manager, go to View » Advanced View, go to the Projects tab, click on the entry (or entries, if there’s somehow more than one) for Rosetta@home, then click Remove. If the Remove button is disabled, you need to go to the account manager that you used to add Rosetta@home, and remove it from there. Then to add it back, go to Tools » Add project and enter https://boinc.bakerlab.org/rosetta/ in the Project URL box. Note that there is currently no work available on Rosetta@home, so even if you do remove and re-add the project, you probably won’t receive any new tasks. |

Problems and Technical Issues with Rosetta@home
(Message 101063)
Posted 4 Apr 2021 by Brian Nixon Post: This issue was discussed recently in another thread. As well as claiming they needed 6.6 GB of RAM, the recent work units were configured to require 8.5 GB of disk space. With a preference setting maximum disk usage to 10 GB, and more than 1.5 GB already in use (around 2 GB is normal for R@h), the server was unable to send those tasks and so issued that warning. Resetting the project didn’t make any difference because the disk space that freed up was immediately consumed again by the smaller tasks you were able to download. |

Posted 4 Apr 2021 by Brian Nixon Post: This issue was discussed recently in another thread. The work unit got resent because the first machine hadn’t completed it by its deadline. But 10 minutes later – after you’d started the resend but before you’d finished it – the other host submitted its results. I think you’ll still get credit if you complete it before the deadline, but from the science perspective there’s no point because the results are already in. |

Posted 4 Apr 2021 by Brian Nixon Post: Is the restriction really needed?Probably not. Your conclusion is correct; the high RAM requirement seems to be a misconfiguration. Perhaps it will be corrected in the next batch of work units; try again in a couple of days’ time. |
