Well, as it stands right now, Seti is the most successful distributed computing project on the planet. The references supercomputer was actually#1 as of 2015-11. As of 2016-06 it was overtaken by one that benchmarks nearly 3 times faster. https://www.top500.org/list/2016/11/ If the benchmark figures of the Top500 list were comparable to our computing numbers then we would be sitting at #218 on the Top500 list. Even though the numbers are not directly comparable I would say the kitteh persons statement "Amassing a power, as far as I know, greater than some of the biggest baddest supercomputers on the planet." is most certainly true. SETI@home has a very respectable amount of computing power supporting it. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Some of the "biggest, baddest" supercomputers means to me most likely the top 10 or 20. The Top500 list is based on a specific benchmark https://www.top500.org/project/linpack/. Given the value that BOINC generates for FLOPs can be rather sketchy I don't imagine any organization would use its output as a legitimate benchmark. It is not even useful to compare different BOINC projects. Generally Supercomputers are in one location as the high speed interconnects they use tend to be limited in maximum length. I'm not sure that how far apart the computing nodes are is in the definition of a Supercomputer. More so that the nodes are interconnected. Where in a system such as BOINC each node is independent and there is no inter-node communication.

Some of the "biggest, baddest" supercomputers means to me most likely the top 10 or 20. . . Since they function as an integrated unit serving a common function then yes I think it should too :) Stephen . |

Well today's 9.5hr long outrage saw my 1060's out of work for 6 minutes this time before the servers came back online, another few more minutes and I would've grabbed some backup work for them (so much for that 3-4hr notice these days). :-( Cheers. |

It seems like 5-6 has been more typical for the past few years at least. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

Well, as it stands right now, Seti is the most successful distributed computing project on the planet. Geez.....dunno where I got the thought stuck in my head that Seti was higher up on the list. Thanks for the corrected info. Meow! "Time is simply the mechanism that keeps everything from happening all at once." |

There was a time years and years ago that the outage really was only a few hours. I don't recall exactly when they started going a bit longer, but I suspect it was some time after GPUs started being a thing and the DB grew much faster than it had previously. As for the "connectivity issues for a few hours afterward," that's a leftover legacy of the servers being up the hill in the SSL when we were limited to a 100mbit link, and older slower servers to handle all the requests. They've upgraded to more-capable servers, and are on gigabit now, so the connectivity issues due to congestion seems to only last for 20-30 minutes now instead of 4-6 hours like it used to. I agree that the message could be tweaked a bit to be more relevant to modern times, but in the list of things that need attention, that one is somewhere down at the bottom of the priority list...although it would literally only take about 30 seconds to change it next time someone is in there making adjustments and tweaks to the web interface. Just saying. Linux laptop: record uptime: 1511d 20h 19m (ended due to the power brick giving-up) |

That was my observation as well. For the past month the outages have all been quite long. Stephen . |

Interesting Status "Didn't Need" ??? Strange! Especially since some of the other info seems to be contradictory. Unclear if this WU has been completed, for example ... Looking at the clients tasks, there are several more in this state. Also, there are some other errors in that clients work status, including 17 WUs shown as error, but do not list when looking at task status 'Error'. |

That's what happens when Eric waves his magic wand; ...I've rereleased them at 8.23 and cancelled the results for the bad app_versions (8.22 opencl_ati5_SoG_nocal and opencl_ati5_SoG_cat132). I'm surprised they weren't given full credit to boot...I've seen that before. Perhaps he's changed wands... |
