I only have a three day cache and I have had no problems keeping the farm working although, It did come close once. I love the idea of a web dev team. I can provide a test server. I think that S@H should 'outsource' some tasks to volunteers (an even greater idea would be to use the BOSSA platform that's in dev for stardust @ home to grant credit for this). anyone like this idea? I'm a Prefectionist ;) |

I'm too laxy to look it up, but when did the credit drop? When I was crunching using the KWSN code (it must be a while back) my 3.2GHz Prescott was getting a RAC near 1000. With the new AK port crunch times have reduced but I forecast (based on credit and wu completion times) that this same machine will only get a RAC near 1000 even though the crunch times are over 25% faster than when I started SETI again a week ago. Here is the BOINCstats chart for my SETI credit. I know there is better credit out there.... Hence the reason for developers aiming for credit parity. People that are interested in the science crunch regardless of the credits. Those that crunch just for the stats will go where ever the greatest credits/hour can be made. If it's the same amongst all projects then even those that crunch just for stats will then need to decide which project to chose, based just on what interests them as the returns would be the same regardless of which project they choose.

They cut the heck out of credit last summer it seems and stole back all Simon had given us...Seems that is about the time he left. The project managers don't seem to mind running people off. They will just send out more E-Mails asking you to return... AFAICR they used, with permission, optimised code in the general client when they released Seti Enhanced. The credits/hour return was reduced so as not to cause an exodous of stats hunters from other projects. Grant Darwin NT |

LOOOOOOOOOL !!! That's why DA tried to cheat/manipulate the stats sites and started spreadeing a lie about RS claiming way to much credits ... after at least 5 time that he's been proven WRONG. he finally acknowlegded he messed up :) And so on ... proven FACT.
Well not if it's manipulated as DA tried it ! Manipulating stats pages on what he thinks is right... well ... Go figure for yourself .. if you need prove for what i just posted here... feel free to contact me and i'll show you how DA and staff try to manipulate ... Join BOINC United now! |

I'm all for project supplied applications claiming parity amongst the different projects (optimised or not), but when private citizens optimise those apps to reduce crunch times and then have the project REDUCE the credit is just plain stupid. |

The stupidety lies in the volunteers adopting optimized code into the stock app... that's the cause why we all got cheated here again ... Good thing is that not all prjects are that messed up like this here... i'm thinking about throughing it all in the junk... once again ... why was i so stupid to start that porting to linux thing again ? Especially while 3 other projects are on my list ... nqueens, 3x+1 and milkyway ... seems to be some kind of stupid habit ... if feel ashamed for that one :( Join BOINC United now! |

They will just send out more E-Mails asking you to return... So in return there was a rush away to other projects... Official Abuser of Boinc Buttons... And no good credit hound! |

Hence the need for credit parity so those that crunch for the stats & not for the science don't hop between projects. Grant Darwin NT |

Either my medications are taking hold of me or......... My browser cache is messed up or................ My memory is failing.............. There seems to be a lot of posts missing now............ |

Uh, no. Private citizens optimized the default SETI application. People using the optimized app. got a credit "bonus" for running the optimized app. Those same individuals gave the optimized code to the project, which then incorporated many of the optimizations into the standard app. Since the standard app. by definition should produce 100 credits/day on the "standard" hardware (see this definition) and the standard app. was now much faster, credit was brought back in line with the definition. This has been argued ad-infinitum. Either the cobblestone has a standard meaning or it doesn't. If it has meaning, then the standard machine should produce 100 cobblestones per day running the standard app. regardless of how optimized that standard application is. |

So other words...The new app will be a waste of time as they will just lower the credits again? Official Abuser of Boinc Buttons... And no good credit hound! |

If, at some future time, SETI makes Alex Kan's optimizations part of the standard application, then we get a faster standard application, and the credit should be adjusted to make that standard application produce 100 cobblestones per day on the reference machine. My understanding, from watching the threads (especially JDWhale's work on SSE2) is that these optimizations require CPU features that aren't on every processor, and it seems unlikely that SETI would "lock out" participants by requiring a higher feature set. Those running optimized apps. start with standard, install an optimized application, get a (justified) advantage from the optimizations, and when the standard app. is improved, you lose some of that advantage. Those running standard apps. start with standard, get a faster standard application, and their credit stays level. |

... JDWhale's substitute intrinsic macros are SSE, so those changes will reach further back. In addition, there are structural improvements in Alex Kan's code which will provide some level of improvement for my 200 MHz Pentium MMX or your VIA C3. Those running optimized apps. start with standard, install an optimized application, get a (justified) advantage from the optimizations, and when the standard app. is improved, you lose some of that advantage. The cross-project credit rate comparisons include all hosts which have done work for more than one project since the credit_per_cpu_second feature was added. I suspect that those who are particularly concerned about credit may have tried out other projects more often, so have more effect on that comparison than typical participants. In any case, it is the intent of open source to have improvements incorporate back into the stock code, and I intend to keep that feedback working. The goal is to get the work done, and although credits can be fun I simply am unable to really understand why they become so important to some participants. Joe |

The reason credits have become so important is that there is NOTHING ELSE here to gauge your own work or the work of the entire project. NOTHING!! |

As I said "I'm all for project supplied applications claiming parity amongst the different projects (optimised or not)...." So if I run the stock SETI app then I'll get the same credits/day here as on another project running their stock app (like MalariaControl.net)? |

NOTHING!! In which case the number of credits you get doesn't matter when compared to other projects. Unfortunately though there are those for whom the number of credits is what counts, not the work done, hence the necessity to keep parity between projects. Grant Darwin NT |
