Hopefully it means something to someone somewhere.Ah: divided by a common language… :-) I was going to say that, but what about the Y B and X? |

same here, 10x C4s waiting for work due to the 6GB requirement. Hopefully soon there will be a lot of tasks for the small computers available. In the meanwhile i let them crunch WCG. |

I have never seen such easy Rosettas. They all under 500 MB on 50 Ryzen 3000 cores (Ubuntu 20.04.2). But there is always WCG. PS - Even less on Win10. Under 200 MB on 10 Ryzen3600 cores. |

The read-write sections cannot be shared between tasks, but all the tasks running can share a read-only section. |

I allocate 28Gb from 32Gb totalOnce you've started them, I wonder if Boinc adjusts to what they're actually using, or leaves the requested 6.5GB there just in case? You could see what happens if you try to run only Rosettas. I've speculated that's the case too. Demand a maximum amount to start, then let the task decide once it's running. I cleared all the problem tasks on my laptop before by setting NNT to Rosetta & WCG and only when all other tasks had completed did my problem task start. That was a while ago. Now I've got another one problem Rosetta task. I've suspended all unstarted Rosetta tasks, set NNT again, kept my last few WCG tasks so that as each of the 3 running Rosetta tasks finish, it switches to less-demanding WCG tasks to see if enough RAM is freed up. If it isn't, let the WCG tasks complete as well until there's only the one problem Rosetta task. If it runs, fine. If it doesn't, abort it. What a performance... ![]() ![]() |

What? It's a valid point. Why would you think a biologist knows about the code?They have to be taught at some time. Which activity do you think they are allowed to do first? Or do you think that they can start both at the same time, with no tests of what the are doing works properly? When you're in a hole, stop digging ![]() ![]() |

What? It's a valid point. Why would you think a biologist knows about the code? All the cool kids who work on projects like this one, using proprietary software, know how to code, grandpa. Like just about everything else in life, some are better at it than others. Some are experienced and others are not. SiDock@home is chugging along merrily on most of my boxes. I'm getting the memory appetite notice on the boxes with less than 8gb of RAM. One box scooped up some projects for Rosetta@home, so the comment that they are squeezing out a few every so often seems to be correct. |

Over the course of this afternoon I’ve had 6 segv errors, all on files starting miniprotien. Anyone else? Or do I start checking my hardware? |

If it's too big, I run it on a bigger machine. My PCs have 8, 8, 8, 16, 36, 36, and 64GB.I allocate 28Gb from 32Gb totalOnce you've started them, I wonder if Boinc adjusts to what they're actually using, or leaves the requested 6.5GB there just in case? You could see what happens if you try to run only Rosettas. |

Sometimes they're interesting. There's the drhicks ones. Some Universe tasks said "on_error" which is rather pessimistic. I wonder what Rosetta's "save all out" means?Hopefully it means something to someone somewhere.Ah: divided by a common language… :-) |

I'm not in a hole and I think you're confusing the two people you're replying to.What? It's a valid point. Why would you think a biologist knows about the code?They have to be taught at some time. Which activity do you think they are allowed to do first? Or do you think that they can start both at the same time, with no tests of what the are doing works properly? |

I disagree. I'm sure you can become a brilliant biologist without knowing the first thing about coding.What? It's a valid point. Why would you think a biologist knows about the code? |

All the cool kids who work on projects like this one, using proprietary software, know how to code, grandpa. +1 They are not pure coders, they are biologists that use code. They want results, not to create "beautiful" (and optimized) code. And, in the past, Rsj5, analizing the rosetta sw said that is "fluffy code". |

I just suspended a task that has been running for 16:19:35 (stuck at 00:10:15 remaining). Any ideas how to get this one to finish and get credit for it? |

It sometimes helps to shut down BOINC, then restart BOINC and then the task. Progress seeming to freeze near the end of a task is often a sign that the task was created with a severe underestimate of how long the task would run. |
