Posted 10 Mar 2012 by frankhagen Post: It runs 4 tasks at the same time. if you want to finish 2 of them, kill those other 2, and set boinc not to request new work. as i said, they will definitely run a lot faster, but if they'll finish in a week - hard to tell. However, for what it's worth, it runs completely and directly on solar power. It only needs 15W to run, so in terms of energy efficiency, it is very good.Total computing power is not exactly great. i definitely did not want to critize you - it's just too tough of a job for that host. at least as long as the default deadline is not extended. but you should be able to run the other app - "Get Bounded Decics". i'd limit boinc to use only 50% of processors on that host anyway... |

Posted 10 Mar 2012 by frankhagen Post: The tasks have been running for about 168 hours and reached about 57 %. that's a really slow host and for the worse you probably did not disable HT. way too slow for running bound decics with the current deadline. you might be able to save 2 of them by suspending everything else, but that's just a guess.. |

Posted 9 Mar 2012 by frankhagen Post: If you double the deadline you'll wait twice as long for the first result to return but once the ball gets rolling the results come back just as quickly .... nope - 4 weeks deadline for getdecis should be fine and be nice even for part time crunchers. |

Posted 8 Mar 2012 by frankhagen Post: May I ask, why you prefer the GetBoundedDecics app? Is it the shorter run times? exactly. Because hourly credit is the same for both. I understand if you don't like waiting days to finish a WU, which takes even longer with an older (and slower) CPU. that's not the problem. i am currently running most of them on a laptop which has only a few hours of spare time for boinc. |

Posted 9 Dec 2011 by frankhagen Post: I get 3.4 GFLOPS on my core i5-2500K @ 3.3GHz. Host 1461 gets 5.3 GFLOPS, a 56% increase. Overclocking by 56% does not seem unreasonable. And how accurate are the benchmark tests anyways? LOL! only bogomips are less accurate. I know I don't get the same values every time I run the benchmarks. And then there's the question of linux vs. windows (my core i5 runs windows and host 1461 runs linux); in my experience, code built on linux is faster than the exact same code built for windows - so I wouldn't be surprised if benchmarks on a linux platform beat the benchmarks on a windows platform for the exact same type of CPU. current boinc clients for linux64 are built with GCC and are much better optimized. my I5M running win32: Measured floating point speed 2601.5 million ops/sec Measured integer speed 6286.39 million ops/sec same machine running linux64: Measured floating point speed 2957.11 million ops/sec Measured integer speed 14869.31 million ops/sec if someone compiles his own version using GCC 4.6.x for a machine that supports AVX - go figure. |

Posted 22 Nov 2011 by frankhagen Post: I've asked the BOINC developers to re-instate the server code DCF safeguard against over-allocations like this, but I didn't get a reply. It might help if this project (and other projects with what I've called "non-deterministic tasks" - tasks wehere the runtime can't be predicted in advance) could re-inforce the need for server code which guards against over-allocation. pin-pointed! but you might concur to what i learned over the years - they will not learn a lesson, but keep frickeling around. they do not fix the ancient porblems which are still around, but come up with new fields like MT-apps, VM-integration, open-cl support and so on. so it's getting worse and worser - and for my measures, this is way beyond FUBAR in the meantime. |

Massive drop of credits per CPU hour
(Message 389)
Posted 22 Nov 2011 by frankhagen Post: Also, thumbs up to @Senilix for spotting the underlying problem :) YUP! what's rock proof by now: creditnew is using elapsed time not cpu time - that's where you earned your merits. this was introduced probably when AQUA showed up with MT-apps and the client reported cpu time of a single core. crazy enough, because elapsed time can be about everything + cpu time. just think about virtual machines.. creditnew is still using those faulty benchmarks to calculate credits, so it's totally open for cheating. creditnew will not work for projects that have WU's with largely various runtimes. it will simply continue to grant random credits and send way too much or way too few WU's and by that foul up everything hostside. |

Posted 21 Nov 2011 by frankhagen Post: Not sure how to "get rid of it", as it's embedded in the latest server code. yes it is - the default. but, taken from the MOOwarp boards: "There's actually four credit systems* in the BOINC validator code by default. First is that dynamic scheme for "device neutrality", second one is to get credit from WU (which is what we use), third is to grant no credit (instead trickle calls can grant credit) during validation and fourth is credit based on runtime (a new one implemented recently by DA for the cases where creditnew doesn't work well)." go read the docs... |
