What are you trying to tell me Gremlin2?

David.
I am not trying to 'tell' you anything, the stats say it all. As already stated, not everyone gains very much by running the BOINC agent. |

Sorry Gremlin2 I saw the post with just the results.
----------------------------------------If you are running boinc and ud on the machine then your boinc points for that machine will be halved so you are right they are not out of this world but what you haven't published is the ud score (added) from the same machine. The point is that we shouldn't have to encourage people to use the new agent the old one worked just fine and to be fair some sort of parity between old and new needs to be established - that's all I am saying and you would have to agree |

btw can anyone explain why the Boinc agent uploads a couple of files after each result 17/02/2006 03:52:14|World Community Grid|Started upload of faah0179_atv_x6711_00_1_0 17/02/2006 03:52:14|World Community Grid|Started upload of faah0179_atv_x6711_00_1_1 could it be that we are getting 2 results per work unit hence twice the points? Me again David, you are not getting 2 results per work unit I'm afraid - nice though it would be! The number of units download to your machine depends on how often you have it set up to communicate with the server in your default profile (the default is 0.1 days) - the longer the gap, the more units it downloads to make sure you have enough work until the next time it communicates. For example if you know you are going to be without an internet connection for a few days, you can adjust the setting prior to this to say 2.0 days, and it will download numerous units to cover this period to enable you to crunch away, then when you get back on the net it will upload all the completed units in one go. Folks need to be aware of storing up too many though as this obviously slows down the validation process for others ('WU Hogs') I hope this helps As regards the points issue, you really need to be careful about comparisons, particularly over a short period - Boinc can fluctuate quite significantly from one day to another due to how long the validation process takes - I also quote Knreed as regards trying to use points per hour as a comparison: The two agents measure time differently. The UD agent measures the amount of clock time that elapsed while the work was being processed. The BOINC agent only includes the time that the thread was actually executing. This means that comparing the points per hour of runtime between the UD agent and the BOINC agent is not a valid comparison. Ady |

The problem as I see it, is not with Boinc but with the UD Agent, its benchmarking is now very outdated and has not kept up with the faster CPU technology. Yes the UD Agent has given great service, but time moves on, and we have to move with it. Ady |

On Gremlin2's machine - the very same bit of hardware in both cases
----------------------------------------Assuming that both agents are running at the same priority level (which given that they both produce results would seem to be the case) The UD agent returned 41.22 points per hour whereas the Boinc produced 48.73 points per hour, that's an 18% increase for no extra crunching As I say I'm going to watch my output over the next couple of days to arrive at a reasonable correction factor - saying that we must move on to boinc shouldn't mean that we loose a level of correlation with our UD history otherwise all the stats, and I'm sorry for the pun, are pointless. Btw those are uploads not downloads from my boinc - after each result I get 2 uploads  Dave edited for shoddy grammar  [Edit 2 times, last edit by David Autumns at Feb 17, 2006 9:45:11 AM] |

FAAH uses 2 files per workunit. UD compresses all the files into one load. BOINC leaves this step to be done (or not done) by each project. Someday we will implement compression for our BOINC projects.

The maths in the post above Mycrofth's does not represent the increase if just the boinc client was running
----------------------------------------I think I should have taken more notice in those maths classes (it's all statistical and hyperthreading throws another factor into the inner efficiency of the system) Anyone out there with a degree in applied maths? |
