I would want it to catch up. But if Rosetta is not sending out work units, so some of my cores are idle, I do not want my Boinc client to ignore other, lower priority projects because it is so desperate to get work from Rosetta. N.B., the worst offender is not Rosetta, but Climate Prediction and, until recently, WCG.I don't understand. If a project is out of work, Boinc will try the next highest priority project in your repertoire. Are you saying Boinc sits there without filling all cores? That simply doesn't happen with me and should not be happening with you either. Boinc will try the one it wants work from, and when that project has no work, it will try the next most important one and so on. That is one of the most basic things Boinc is supposed to do. |

Furthermore, it seems to me it takes much longer than a month to approach my desired ratios, even when all projects are continuously sending out work.Because you are running multiple projects with a large cache. The more Projects you run & the larger the cache, the longer it takes for your Resource share settings to be met. It's that simple. Grant Darwin NT |

That and backup projects should be set to 0% and not something like 0.xx%.Furthermore, it seems to me it takes much longer than a month to approach my desired ratios, even when all projects are continuously sending out work.Because you are running multiple projects with a large cache. . |

Store at least 0.50 days of workYes, I have 0.25+0.25 with about 5 projects (I have loads more, but I choose a few at a time). You only need as much as 2 days cache if you want to grab a huge amount when a project becomes active, or if you have a flaky internet connection. Although the first one won't work, as it will also grab a lot from other projects. I usually set the first figure to 0, but increased it so it pesters WCG for work. |

Store at least 0.50 days of work I do not need to grab a huge amount, but only enough so I can coast over the intervals where a project does not have a supply of work usually available. I decided I would like to have a day's supply of work availlable so a project could skip sending me work every other day. But with my main projects all being just awful, in the last year or so, at supplying work on a regular basis, my processors are frequently idle. I would think having a day's work in reserve to be quite modest. My internet connection, with Verizon FiOS, is extremely reliable. This test does not give the reliability, but it I cannot remember an interruption in service this year. They were down fo an hour or so somewhat after midnight the year before, but I was asleep at the time, so it did not affect me.

Aluminium, wires installed in 1979 back when copper was too expensive. I've had about 30 engineer visits. But for the last 10 years I think they've fixed everything. 89 up?! Bloody hell. I get 34 down (was 54, but they dropped it due to contention, or me using it too much for illegal activities, they might be lying) and only 8 up! Everyone in the UK has a very slow up, seems to be the in thing to give you most of it on down, which I suppose makes sense.Netprotect New York, NY Test results Ping 5 ms Jitter 1 ms Download 78.8 Mbps Upload 89.1 Mbps WTF is a jitter? |

[snip] When I was working as an electrician's helper, I saw one on the problems with aluminum wire. It SLOWLY moves away from whatever is squeezing it. Therefore, unless you keep constant spring tension on it, you'll eventually get an open circuit (a gap breaking the connection). |

Everyone in the UK has a very slow up, seems to be the in thing to give you most of it on down, which I suppose makes sense. My Verizon FiOS is fibre-optic to a box on the outside of my house. There the signal is converted to 4 voice lines, one ethernet line, and a co-ax for television ("cable"). I actually use only one voice line, but I did use two for a while. And I do not watch TV, so I do not need that. The ethernet line goes to a Verizon-supplied router that is hard-wired to my main computer, to a littlle Windows10 computer, and my UPS that keeps in occasional touch with the UPS vendor (APC). In any case, I pay for 75 Megabits/second both up and down. And Verizon exceed those speeds almost all the time. I could pay more money and get ten times faster, but I would probably need a new router, and a new box on the side of my house (box now 18 years old). But my data rates to and from most servers is slower than what I have now to the various sites that that test program uses for measuring Internet performance, so I would not benefit from a faster connection.. https://www.speakeasy.net/speedtest/ I do not know how the test program measures jitter, but it must measure how steady the pulses are. One way they could do that is to do a bunch of pings and watch the variability of the ping time. |

When I was working as an electrician's helper, I saw one on the problems with aluminum wire. Ahh! Yes. I used to work in a very fancy office building designed by Eero Saarinen who was a pretty good architect, but there were a few screw-ups. Aluminum wire for the main feeders, though copper to each office and each laboratory. I used the services of the plant department when installing a new computer for our work. And the main engineer in the plant department and I became pretty good friends. Several times a year he went to each and every power panel where the aluminum wire was present and measured the temperature of each connection with an optical infra-red pyrometer. Anything that was too hot got fightened or the wiring replaced. https://www.midcenturyhome.com/eero-saarinens-bell-labs-holmdel-complex-collaboration-reignited/ |

You have fibre to the house and aren't using 1 Gbit? Can we swap houses please? "Wouldn't benefit" WTF? Everything can go faster. What use is 1 GBit (my NIC will go that fast) to me when the servers at the other end, such as WCG, only go around 40 to 60KBytes per second. Increasing my peak rate from 75 Megabits/ second up to 1000 Megabits per second will make no difference at all. Everything at my end could go faster but the throughput is no faster than the slowest link in the chain, and I somehow do not think from here to Canada (where WCG is now located) wil go any faster no matter how fast my end is. Sending their signals through US border control incurs huge delays (just kidding). FiOS is a data service from Verizon that is fibre-optic to the home. They offer different speeds for different prices, but I am paying only for 75 Megabits/second up and down. |

The worst of all is with fine multistrand copper wire that has its end soldered to a `nice` blob then screw fixed , it wont stay fixed for long :-(Just twisted up also comes loose, so does non-stranded solid copper. Maybe the screw undoes with vibration? It could be glued? Or is the wire moving or compressing? Big current stuff here is done up with two or more grub screws in a row. And you shouldn't have the wire under any tension so it pulls out when it gets loose. Gah, that sentence is so untidy, this stupid forum removes my double spacing between sentences. And yet it can't get the line spacing right.... |

I assume you don't only use WCG? Most places will go way faster than your current connection. Especially piratebay! My favorites now, in order, are ClimatePrediction, WCG, Rosetta. I also am doing universe and milkyWay to soak up unused processors because ClimatePrediction sent me only one work unit in the last 4 months (Nov 7) that bombed out with invalid theta. 4 other users bombed on that work unit too. Except for that one, the last work unit I got from CPDN was at the end of July. I had about an 8-month gap in WCG work units. And Rosetta does not keep up with my machine either. I used to do Seti@home and Malaria, but they are gone. IIRC, none of those go faster than my connection. |
