Hi SekeRob,
----------------------------------------I thank you for your answer, but I cannot agree with your remark because, one year ago, with a broad project mix, the daily average contribution was higher than today. Over the years, I observed that FA@H (in the past with Autodock) did not granted much credit in comparison to other projects. During the last four months, with a FA@H - CEP2 only mix, I was on the above mentioned daily average: around 17'400. 1.5 years ago, I was at around 20'000 since it seems that HCMD2 was a little bit more generous. IMHO, the low credit rate with MCM on Linux platform looks like missing optimisation. Cheers, Yves ---------------------------------------- [Edit 1 times, last edit by KerSamson at Dec 7, 2013 4:22:42 PM] |

Yves,
----------------------------------------It seems you've made up your mind, so the way it works with me it then to just not proceed and present more blunt visible evidence in the Linux client, that it's the Linux OS processing VINA 65-70% faster than Windows [probably Mac too]. Think there's a cruiser full of members, not with Capitano Schettinno at the helm, our national coward, that can confirm that... which is why Linux on VINA makes piles more credit than Windows per unit of time, for those sciences. Nothing to do with comparative MCM poor performance... they are close across the different OSses AFAICT. Summary: Switch from VINA to MCM on Linux and a device will start to show substantially less credit per day. Maybe the techs could post mean run times for the different main platforms for sciences. Since work comes from the same pool, the large number statistical average would on-par performance be close enough. It may give a more general incentive to [dual boot, which is easy, or VM] into Linux for more results per day, and a little project cherry picking. Nothing wrong with that in my mind... more science contribution. (and now we wish once more to have WCG measure performance and assign, optionally, the work that a device is best at). edit: spellcheck.

I would say that the disparity between Vina and non-Vina is easy to understand when it comes to work done but what I have always found difficult to grasp is how same project calculations are arrived at.
----------------------------------------MCM1 is said to be of varying length as the work is hard to predict when building a wu. Yep OK I get that and I therefore presume that all work is of a similar nature, but the "points claimed" part of same project wu's is all over the place and for the life of me I cannot understand how, even this part alone, is calculated. By way of example let me show a couple of pics to illustrate: This is sitting in pv and thus there is no need to mention points awarded but here the longer runtime has claimed less. WHY ?? The rig has been running for weeks so I would think that by now this single project has a handle on what it is capable of and can give it a points per hour figure to use when making a points claimed assessment. This time more of same but with Valid results. If I could only get a Logical answer as to why run longer, which in my book means "do more work" gets to claim less points then maybe I would be less annoyed with this system. For all that points are a by-product of getting the work done it would be nice if whoever wrote the system could flesh out the thinking behind how it works. ![]() |

OldChap, I know the particular problem and what the root cause it. Either WCG addresses this on it's own [knreed needing to carve out several weeks of analysis and testing by his own words, using major server resources to facilitate], or does some bionic powered arm-wrestling with Dr.A in Berkeley to get this issue out the way for Credit-NewV2. Did a crunch on another project for a week, outside of WCG, to get the evidence and the issue was thoroughly confirmed, to me... Credit New v1 is a hairless dog, a thorough waste of time to debate at our level... oops I said it again).
We just could collectively ignore the issue for good and let it be as the weekly rerubbing is getting tiresome... yet another thread [this one no exception]. We crunch for results and within WCG there's no inter-cruncher disparity over the longer run. At an individual result level... |

Wishful thinking Rob. As long as the system is perceived by the users as being broken/wrong/not working properly/etc. etc. I feel you will be needing to be keeping on with the replies.
----------------------------------------The simple answer would of course be " It's broken some and it will get fixed when there is time" Nice task to give the research junior or whatever you call the Office junior in Scientific establishments ![]() ![]() [Edit 1 times, last edit by OldChap at Dec 8, 2013 4:36:21 PM] |

No, every time someone starts a credit poke, I promise myself -not- to get involved. My next time will be posting a link to the Berkeley forums.... take it up with them.

Time to poke again?
Runtime down (end of BETA's) and start short FAHV's -> credits go sky high: ![]() |

Time to poke again? 2 days later and no reaction from the admins or techs. Didn't expect that.There's really something wrong with WCG's credit system and it's not only the fault of the introduction of BOINC's Credit New. Date Runtime Points Results Pts/hr |

for some recents valid wu's
----------------------------------------CPU Time / Elapsed Time (hours) Claimed/ Granted BOINC Credit time // points 3,57 / 3,95 170,9 / 186,1 3,59 / 3,99 178,1 / 181,5 7,20 / 7,20 268,4 / 225,1 7,19 / 7,19 245,2 / 190,8 4,45 / 4,45 168,3 / 117,2 i may not have understood well all what was explained in the previous posts but i think MCM is not very generous on credit points u see CPU Time and Elapsed Time equal and the big difference in claimed and granted points sure i am making slow progress for a new badge...? ps:sorry for the presentation, the last 2 columns are the pts ![]() |

i ask again abt why MCM (or is it Boinc ?) is so stingy granting pts
----------------------------------------here an exemple: 09/02/15 13:04:00 3.60 / 4.01 164.6 / 161.3 09/02/15 07:40:57 3.59 / 4.01 174.8 / 167.4 yu see in my results on the same CPU time the difference ag me pts claimed and pts granted for the time we crunch the pts granted are many times minored by 10 or 15 pts why so?? ![]() |
