A couple channels of AP in the works, yea! (and me with a full cache) ;-) |

Forgive my naivete', but what's the big deal about AP? I ran a couple last week and they completely tied up my pc. I have 2 available cores for seti to use when necessary, but the ap's decided on their own to bump one of my cores dedicated to cosmology. I didn't like that. So I turned ap's off. |

Yes, I noticed that AP was up as well. I have dumped all my v7 wus and am filling up on AP again ... |

From what I have gathered from reading this forum, with the new credit system, APs give more credit per time than the MBs do. This is probably only half right, so corrections welcome. :) |

I'm not in this for credits, so you good folks can have any ap's that might have come my way. Good luck with them. |

No corrections needed. You are basically correct. v7 wus give you about half the rate per hour that AP wus give. Where as v6 and AP wus were fairly well benched marked against each other (so it didn't matter what you ran), v7 gives you about 50% of the rate that AP does, so it it always better to run AP over v7. You only go back to v7 when there are no AP wus left... cheers |

Don't give them any new ideas. let those that want to run v7, run v7. I've split my machines so that one runs AP and the other runs v7. Works out real good that way. The only problem is that there are more v7 (MB) than AP. Sure glad the drought was only for the weekend. I don't buy computers, I build them!! |

I've just been doing AP-only on my main machine for... wow.. um.. I remember the big switch to ap_v5. They were taking about 160,000 seconds, and that was with the optimized apps. Now a few generations newer (32nm now versus 90nm then) and some extra GHz, I'm down to about 42,000 seconds on average. I don't care about the credit. I don't even know how much I have or what my RAC is unless I happen to see it next to my name on a forum post once in a while. I just prefer it because they take longer and there are less tasks at any one time and it just seems to be more tidy from a logistics standpoint than MB. The credits for v7 should continue to increase over time.. though we all thought it would have by now, but apparently it hasn't.

The fact will remain, multibeam tasks need to be done by some of us just so those who want astropulse tasks can get them. ;-) Cheers. |

I am doing MB 7.01 tasks on one Linux box and Astropulse by Lunatics on the other. I was doing SETI@home 6.03 on my Solaris Virtual Machine but it seems they are out. Tullio |

I only do AP's on my CPU's, if I get them, but I prefer to just do multibeam work as there's plenty of it available, and someone has to do it. Cheers. |

I'm not in this for credits, so you good folks can have any ap's that might have come my way. Good luck with them. I second your feelings. If I get some AP's great! I think they help search for new black holes ~ that's pretty cool too. I just let things run their course, and what I get, I get. Some people go to large lengths to get APs over MBs I think. |

AP now dry, so in about a day (which is how long it takes to do 100 AP GPU wus) it is back to MB until AP surfaces again... |

APs.... almost as mythical and elusive as Bigfoot or Nessie herself. LOL |

Maybe more so ... :)) |

That did not last long. |

AP is up again ... caches filling nicely (after dumping all v7 wus) ... they should be around for a day or two ... grab them while you can :) |

Actually I'd have to say that that is just plain wrong (a lot could call it just plain cheating). The database is having enough disk I/O problems without you adding to it by throwing away work to be recycled again. :-( Cheers. |

It's not cheating as such, it's gaming the system. The system can be gamed at a superficial level due to the imbalance in credit rates caused by v7 and CreditNew and I'm not the only one playing the oscillation game. The issue can be easily fixed though, Dr Anderson just has to fix the credit system. cheers mate |

probably not a good idea to cherry pick your work. Many projects including this one disapprove of users dumping work to get the choice work. If you don't want V7 don't take it. both work types are needed to be done. In a rich man's house there is no place to spit but his face. Diogenes Of Sinope |
