Large numbers of tasks aborted by project killing CPU performance
(Message 97290)
Posted 8 Jun 2020 by ![]() Post: You OBVIOUSLY have NOT been a Boinc cruncher for very long as EVERY Project has experienced shortages of workunits over time, even Seti the first Boinc Project has shut down and is no longer creating any new workunits. In fact there are over 100 Boinc Projects that have started and closed for one reason oranother but yet Rosetta chugs right along still producing workunits!! I admire y'alls patience dealing with him lol. |

Record performances with EPYC
(Message 95067)
Posted 21 Apr 2020 by ![]() Post: The AMD EPYC 7Fx2 series is intended for applications that benefit more from frequency and cache, over raw thread count. However, Rosetta@home is perfectly able to use as many threads as a system has available (provided that the machine has sufficient RAM). Isn't Rosetta L3-Cache hungry? Is it correct that as time goes on, L3 cache will eventually turn into "RAM"? I remember having a computer with 64MB of RAM... and now we have a CPU with 256MB of L3 CACHE. |

Posted 15 Apr 2020 by ![]() Post: My Android pixel 2xl is an arm64 device but it's not getting any Wu's. Something else I need to do? Hmmm, I set my phone to 4 tasks. I don't really check how it's doing in detail, but according to my PC lists, it's doing about 370 RAC, running only at night. My wife's phone is slowly catching up as well. I'm mostly worried about the writing to storage these WUs might be doing... does anybody know anything about this? Amazing, these little phones are crunching as fast as my old computer did back when BOINC got first released. |

Posted 13 Apr 2020 by ![]() Post: I'm not sure I'd use this on my primary phone, just because of heat and battery issues even though it only runs when plugged in... BUT, I did have 2 older phones that I should have recycled long ago in my desk drawer. They are now setup to run this on the corona project 24/7. If those older phones die no big deal. I set mine to use 3-4 cores, and it barely gets warm. It gets way hotter when I'm bored and play stuff on it. I'm a bit concerned about the disk writing tho. Not sure how much each WU writes to the phone's storage. |

Total R@H Computing Power
(Message 94201)
Posted 12 Apr 2020 by ![]() Post: Is the "Current GigaFLOPS" stat in the Server Status page accurate?No. I kinda thought this was the case. I just want to know how "far behind" R@H is compared to Folding compute-power wise. I know the difference if probably huge, considering they can use GPUs. But it'd be good to know exactly how much and keep track of it. It'd also be great to see how R@H compares to a TOP500 Supercomputer and stuff like that. |

(Message 94173)
Posted 11 Apr 2020 by ![]() Post: Is the "Current GigaFLOPS" stat in the Server Status page accurate? I mean, it did go up A LOT during the last few weeks, so it does seem to correlate tightly with how much is being proceeded, but is this number comparable to the number given by Folding@Home regarding their total computing power? I mean 1 GFLOP reported here = 1 GFLOP reported by Folding@Home. |

Partial use of many CPUs vs. Complete use of one CPU?
(Message 93412)
Posted 4 Apr 2020 by ![]() Post: Hi all! First time I've used Rosetta@home in a while in light of COVID. I had a technical question. My computer has 4 CPUs and an AMD GPU (which my understanding would suggest that the GPU isn't particularly used by Rosetta@Home). In my opinion, if your CPU has HT, set it 50% number of threads when working on the PC. If you have a dedicated PC running nothing but Rosetta, then set it to 100% number of threads. I always leave the CPU time setting at 100%. Much rather have half of my threads running @ 100% than having the whole CPU switching on and off every so many seconds. Kinda makes me think there'd be way more thermal stress that way (heating and cooling so often between 100% usage and 0% usage). |

Posted 1 Apr 2020 by ![]() Post: Hi from Germany! Due to human nature, it kinda IS the virus fault tho, isn't it?. So we should worry about the virus because the virus causes panic (regardless whether its justified or not). Virus, catastrophes, or whatever, they all cause damage by themselves AND by panicking the people. We could make an analogy to our own immune system. The common cold doesn't make you feel like crap because of the virus, it's the immune system itself that makes you feel like crap, usually from overreacting. This situation also reminds me of to the Chilean 8.8 Earthquake I got to experience back in 2010. The quake itself wasn't the biggest concern. that's what solid building codes are for... it was the PANIC. But can we really expect people to not panic when there's no certainty about anything? That and the aftershocks, those kept you on edge for a few months afterwards too lol Right now, I truly believe it's better to shutdown EVERYTHING for a few weeks. Otherwise, if we try to contain the economy by sort-of shutting down, then we might not be able to contain it and we'd get the worst of both worlds. Awful economy AND piles of dead bodies. But that's just my guess. |

Rosetta's role in fighting coronavirus
(Message 92738)
Posted 31 Mar 2020 by ![]() Post: Currently, I have 14 machines with 80+ cores and 14+ GPUs. When I switched over to run one of them to Rosetta, from cancer research (WCG), I did NOT receive anything related to covid19. Whenever I would receive ALL WUs for covid19, I will switch over... Till then I will stick with cancer research. Let me know when covid19 is the priority here. I am NOT going to download the fold@home app. If it is not thru BOINC, I do not run it. I agree. If LHC can do a Virtual Machine Wrapper, there's little reason to not have some sort of API/Wrapper/Whatever with Folding (right?). It'd be SO much easier to distribute work between Folding, Rosetta, and GPUGRID. Because right now, it's a manual hassle. It'd be nice to also have some sort of consolidated "credits" thing, to keep track of how much you're contributing. |

Posted 31 Mar 2020 by ![]() Post: Quick question for anyone, yesterday when it became clear that the server was empty I completed my running units, suspended the rest and did a project reset on my fastest set up. My thinking being that I would send my queue back to the server for redistribution. Is that how it works as although my client is empty, I have a considerable number of tasks in the "in progress" section, although I obviously do not. I had to reset the project a couple of times during the last few days as some work refused to download also but that's understandable given increase in users, and it seems that whatever was in the queue is also listed in that section? No, I think when you do a reset, it doesn't abandon the WU. In order to correctly do what you were trying to do, you have to ABORT the WUs, and then update the project thru BOINC Manager. Then, on the site, the WU list will show as Abandoned and should get get resent to other people. By the way, the WUs take the same time regardless of how fast your machine is. If you machine is faster, it'll simply do more models vs a slower machine and get more credit per WU. |

Posted 31 Mar 2020 by ![]() Post: Not only has the coronavirus spiked volunteer interest with our R@h project, but it is also spiking a lot of interest towards R@h within the lab so the communication should definitely get better. A lot has happened in a short amount of time. Please post this on the homepage! Very informative. Thanks for the update! |

Posted 30 Mar 2020 by ![]() Post: My computer does not receive new jobs, maybe they are over. Waiting from China for i5-4690 instead of G1840. According to the Server Status page, R@H is basically out of WU to send. Over 1.4 MILLION WUs out in the wild being crunched. I don't recall a time when there were so many WUs distributed out in this project. |

Posted 26 Mar 2020 by ![]() Post: To try and maximize my contribution to fighting SARS-CoV-2, I've adopted the approach of running R@h for CPU work, and running Folding@home for my GPUs This is the best approach in my opinion. GPU for Folding, CPU for Rosetta. For me it makes little sense to do CPU for Folding since they can already do the same work with GPU which are way faster for that kind of work. |

Posted 23 Jan 2019 by ![]() Post: I might throttle back to maybe 75% or 24 hyper-threads. See what happens. I went out and bought 2x16 GBs of DDR4 memory. So the system seems to recognize all 48 GBs of memory. I do not see much of a change in BIONC usage of memory. With 32 Active simulations, my memory foot print is around 13 GBs. You only had 1 stick before? You now have Dual Channel at least. |
