I think with running multiple tasks on the video card you don't really have idle time. So there wouldn't really be ~6 hours of idle time. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

The CPU/GPU itself is not 'idle', the process is idle. There's always going to be a crunching gap when one wu ends and the next is starting to crunch in earnest. My Statistics display in BM has been on a ~10 degree down slope since the shortie storm began around the beginning of Nov. Anyone crunching mostly shorties may see a similar line. Lt |

Yeah my graph has been showing the same downward spiral for the most part. SETI@home classic workunits: 93,865 CPU time: 863,447 hours Join the [url=http://tinyurl.com/8y46zvu]BP6/VP6 User Group[ |

@HAL9000 I probably should not have said "idle"..."not crunching" might be clearer. In my mind they are equal... Lt |

Pulled the 8600GTS. Made no difference. Wouldn't be so frustrating if the WUs ended up as errors. The NewCredit math must make sense somewhere but maybe they are ExtraTerrestial? |

Pulled the 8600GTS. Made no difference. The official word is that CreditNew assures a long term stability on the amount on credits you get and they priorized that over the premise that 2 equal task you should receive equal credits. I agree... Mathematically a random number generator (aka CreditNew :D) also gives a long term stable average... |

Pulled the 8600GTS. Made no difference. The funny thing is that I havn't seen a "long term stable average" since the new credit system was introduced. Cheers. |

Pulled the 8600GTS. Made no difference. Not entirely true. On APs for example. Q4 2010 avg 900 Q1 2011 avg 850 Q2 2011 avg 800 now 700 - 750. It goes stable downwards. With each crime and every kindness we birth our future. |

Yes it's definitely going stably downwards (or backwards if you like that term better). :( Cheers. |

If I remember it correctly, those long AP tasks (or at least those who settled down in order to finish it up) receive much higher credits than the same AP task which finish up in just a short time. Definitely the run time length of a given task determines the amount of credit being returned back from such tasks. |

A quick check thru my valid AP WUs: http://setiathome.berkeley.edu/workunit.php?wuid=861013181 5.90 (granted credit) 45,540.74 (CPU time, by wingman, ~12 hours) 5542.84 (GPU time, mine) http://setiathome.berkeley.edu/workunit.php?wuid=859872786 13.31 (granted credit) 71,981.45 (CPU time, by wingman, ~20 hours!!!!) 12,615.68 (GPU time, mine) http://setiathome.berkeley.edu/workunit.php?wuid=883027112 199.98 (granted credit) 852.07 (GPU time, mine) 56,542.34 (CPU time, by wingman, ~16 hours) I'm quite surprised wingmen are getting so little credit for their CPU time. |

Yes the "new credit" system is really unstable and should be pulled and stuck up...... [self edited] At least with the old credit system you had a good idea where you stood. Cheers. |

Wonky credit continues - many sub 100credit for AP-WUs. I feel bad for CPU wingmen, some crunching for hours (this, 15.58 credit ) or DAYS (this, 13.17 credit!!!). Kudo to this particular persistent chap, 14.48days, 2,959.62 credits. :) EDIT: Maybe a minima 200 credit floor, hmmm? EDIT2: Since I hit 5m over here, I'll be switching to A@H or E@H. I wish the ATI-OpenCL get released soonish. :) |
