There is clearly a priority set up at WCG for certain projects. If I turn on all projects, I virtually never get anything but FightAids and Proteome Folding as an example.
I like the Clean Energy Project and the Nutritious Rice projects too but I never get either of them as work units unless I turn off all the others. There's clearly a priority of which projects work units get shipped out to be done. When I select all the projects, I would expect to get a near equal number of work units from all the projects. Instead I get only two or three projects work units and none of the others. And don't tell me it's because there aren't any work units available as I've verified there are. The current system forces the participant to choose 1 or 2 projects to work on instead of being able to do work for all or many of them equally. I've current set my projects to those 2 or 3 I like best only just because WCG will never give me those work units if certain other projects are selected. Please remove this priority system and give a near equal number of work units to all projects selected. Another possible solution would be to allow the participant to set up priorities instead of just a check box. The current system strongly favors certain projects over others. Also it's about time that WCG comes up with a way to merge unused computers. WCG is the only project I've found on BOINC that doesn't have a way to do this. I rebuild my PCs often and the names are often different when rebuilt. It needs to be possible to merge older machine names into the newer ones so that the scores are correctly reflected per machine. |

Plz see prior threads on this topic. I Don't see WCG deviating from "selected favs", "not selected but send if no favs", "don't send me these because my computer breaks them".
----------------------------------------Equally, no, whatever goes into the feeder with the appropriate 'weight' as has been set by the techs based on availability and load on the server system, by normal, low, high. You will never get 'equal', not quantitative or by cpu time because those that have taken an exclusive get first choice, plus the length of jobs can vary quite considerably. The rest goes in the pool and determines how it's shared out. Sort of in a nutshell and near impossible to administer without bringing the system down, but plz refer to prior threads for full discussion.

I'm not sure I understood the last post.
If there is a prior post and discussion could you reference it so I can find it? I looked through the last few pages of threads and didn't see it. (Not going to read all of the over 1300 threads). So there is a Normal, Low, High priority? Why? A little predjudicial to give one project a higher priority than another, don't you think? "Those that have taken an exclusive get first choice"? What does that mean? Not interested in equal CPU time. It's just that if you select 5 projects you should get to work on 5 projects. The way it is now you won't get work units from 3 of those projects because the main two are all that's shipped. Not trying to be obstinate, just want to understand why some projects are favored over others. |

No, there is no prejudice! As said, there are supply limitations, size variabilities, overall server load considerations.
----------------------------------------If you have 5 projects selected, what are the quantitative ratios you see? As said, if there are many who have a preferred project such as Help Fight Childhood Cancer or Help Cure Muscular Dystrophy or FightAIDS, these eat into the total available 'equal' share. If thus 75% for instance is taken out up front by the exclusive crunchers than only 25% of these go into the multi project pool so yes, you'd see an uneven share from your perspective. Far as I know the current remaining 6 active projects have an overall 'normal' weight, with a quite high demand on HCMD2... their run times in on average 4.5 hours opposed to the other projects doing about 6-7 hours, so you'd see more of those, or less all depending how much is swept up by the 'preferred' contributors. But, let me give you this chart. Looking at the chart, HCMD2 has a higher volume, but they are much shorter in mean, so more are send into the feeders of these. Fairly close it looks to me. BTW, Our recently improved forum software has excellent search functionality, no need to browse all 1300 pages. Type in "project AND priority" for instance.

to put it simply as i understnad it
----------------------------------------no the program dosnt have higher or lower setings for project it trys to keep them all balanced the issue you are experiancing tends to be badge hunting. alot of users are hunting badges (i should be swapin my hunt in the next day or 2 myself) so when this happens and 99% of the CEP work units curently avalible get snached up by CEP badge hunters and same with flu and.... ect.. the server trys to get all its work out so if there are more FightAids and Proteome Folding then it is more likely that you will get those. If you dont have FightAids and Proteome Folding you will most likely get the next ones who have a larger cache FAKE NUMBERS Help Cure Muscular Dystrophy - Phase 2 100 of 5000 Influenza Antiviral Drug Search 250 of 5000 Help Fight Childhood Cancer 400 of 5000 The Clean Energy Project 100 of 5000 Nutritious Rice for the World 200 of 5000 Help Conquer Cancer 400 of 5000 Human Proteome Folding - Phase 2 200 of 5000 FightAIDS@Home 1500 of 5000 Human Proteome Folding 1200 of 5000 total curent FAKE NUMBERS avalible 4350 of 45000 so by this faked example chance of geting 1 work unit from project is Help Cure Muscular Dystrophy - Phase 2 2.29% Influenza Antiviral Drug Search 5.75% Help Fight Childhood Cancer 4.6% The Clean Energy Project 2.29% Nutritious Rice for the World 4.6% Help Conquer Cancer 9.19% Human Proteome Folding - Phase 2 4.6% FightAIDS@Home 34.48% Human Proteome Folding 27.58% again these are fake number but just an idea if there are more jobs curently avalible then you are more likely to see those. hopefully someone better can explain this but i was hopeing to give you an idea  |

Nasjer, you've got the picture exactly right, the remaining pool after deduction of the 'focused' crunchers results taken out of the per-project daily total. That's on a 'all projects' base. It gets even weirder depending on the multi project mix. No idea how that decides, but think a major function in that is also what happens to be in the shared memory at any moment in time.

OK I'll just withdraw this suggestion and not post any more about it as I can't figure out what that chart you provided is showing except that the three projects I want to work on show near 0 on the chart most of the time. Don't really get it. If everything is normal priority, why can I NEVER get workunits some of the projects without turning off others?
I did a search using exactly the two keywords you gave me and I either get 1087 pages of nonrelated posts (except for the ones we have just done here at the top) or frequently I get the error message "Cannot access the lucene search index. Please report this error to web site Administrator (check mvnForumHome or rebuild Lucene index). " To be honest, WCG is just too darn different from the other BOINC projects and seems to be unconcerned about providing info in the BOINC format or supporting the online managers. I've been doing some work units since March and it's a constant task just to figure it out since it isn't presented in the standard BOINC formats on the web pages. I'll just move on to other BOINC projects that conform and not bother WCG with my suggestions any more. Sorry to have bothered anyone with a suggestion. |

Did you put AND in there in capitals? Narrows it down to 387 posts, sorted by some smart logic:
----------------------------------------http://www.worldcommunitygrid.org/forums/wcg/...2&submitbutton=Search In the chart you see 9 ribbons... 3 near the bottom as they are almost done, no more new work. The 6 higher up have an overall equal weight, with some compensation for run time v.v. the number of results per project. In CPU years it looks like this: Pretty darned closely managed I'd say.

Ooops... I was doing the last posting and didn't see nashers last post....I kind of follow that explanation better.
I guess there is no consideration by the server for how the project preferences are set except just to provide the next work unit needing work and that's a majority of the ones I get instead of a smattering of all projects I selected? OK, makes some sense. If I continue with WCG, I guess my only choice is to do what I have been doing. (Locking out all but two or three projects instead of allowing all projects.) |

can't figure out what that chart you provided is showing except that the three projects I want to work on show near 0 on the chart most of the time If from this, I'm assuming you're wishing to crunch CEP, DDDT and the IADS projects, there is a real reason why these are showing 0 (or very low figures) on this chart all the time - and that is basically as these three projects have come to their conclusion. Sorry. CEP (phase 1), sent the last of it's WU's out a few weeks ago, IADS (flu) sent the last of it's new WU's out this past week, and DDDT basically finished in August - with the potential for more WU's to be sent out if/when the scientists involved have more WU's to process (which, so far, has already happened on 1 occasion). Both DDDT and IADS will be being officially set to an 'intermittent' status in due course (indeed, the former already is), whilst CEP (phase 1) will be set to complete - although another phase is due in the not too distant future. Thus, in reality, there are 6 projects, all with just about equal weighting once you've taken out the 'badge hunters' (those who have specifically set their computers to crunch on 1 or 2 projects), or those who for personal reasons, wish to focus their attentions on a specific project. The graph which Sekerob has shown, illustrates as to what the project share is on an on-going basis, i.e., in a 'perfect world', the 6 active projects should get 16.66% each - which, in reality, isn't that far off the mark. Okay, HCMD2 is getting a higher share, although Sekerob has explained as to why (i.e., shorter run WU's).  |
