I have a bunch of machines installed with BOINC and running WCG apps at work. These systems are on pretty much 24/7 and have no trouble completing the work assigned to them in the allotted time. However, I also have my home systems running BOINC/WCG with the same user ID. While they're much more powerful systems than the work boxes, they are not on all the time either. Many times, one or more is not on long enough to complete the work unit before the deadline.
----------------------------------------I'd like the ability to specify what type of project or, better yet, the maximum run-time required to complete a given project, on a system-by-system basis. This would allow me to have one of my home boxes that's on 1-2 hours a day pull down tasks that take 4-6 hours to complete while the work machines and other home machines that are on a considerable amount of time can remain pulling down tasks that take however long to finish. (This system on 1-2 hours/day really doesn't have much chance to complete a task that takes 30+ hours to finish before the deadline, but a dual-core AMD machine doing nothing but play MP3s is certainly powerful enough to do a significant amount of work.) This would obviously need to take the benchmark of the machine running BOINC into account, as how long it takes to finish a project will depend on the speed of the machine in question. |

Use multiple device profiles under My Grid --> Device Manager --> Device Profiles

I saw that, but do not see any place to specify how 'big' of a task to allow. Am I missing it?

HCMD2 are "generally" short 4-6 hours but some run longer. HCC is good too. See the following chart for average run time per project: http://i137.photobucket.com/albums/q210/Sekerob/WCGProjectWorkUnitTime2.png 10 day deadline should be enough for 1-2 hour machines to complete NRW, HCC and probably HCMD2 |

That's cool! Thanks man - it should allow me to get the effect I want.

10 day deadline should be enough for 1-2 hour machines to complete NRW, HCC and probably HCMD2 HCMD2 tasks stop after 6 hours if less than 60 % of the job has been done. Otherwise they can go on to complete it and they will be stopped after 12 hours anyway if it happens that the last 40 % were more difficult to compute than the first 60 %. So if your 1-2-hour machine is that slow that it may need up to 30 hours for other projects then most of the time a HCMD2 task will stop after 6 hours of CPU time. For the few other cases the 12-hour cut off will be the maximum it will take. Note that HCC tasks are short on fast 64-bit machines, but if you run them on an older 32-bit machine they may easily take much time. Cheers. Jean. |

in boinc manager, if you click on "advanced" and then click the "preferences" tab, then click the "network usage" tab you will see a box for "additional work buffer." Set this figure low to perhaps .5 and your machine should then only have one active task and one in waiting to start. Since most of the projects have a 10 day deadline you should rarely if ever miss a deadline, especially if you run the fixed deadline projects. This can be set individually by machine. Good luck and good crunching.

Thanks for the input.
----------------------------------------I think I'm going to set up the machine in question to do HCC only based on the info in your post JM. It's a 64-bit dual-core AMD laptop with 2 gig of RAM, so I'm sure it'll be able to handle it without trouble. Before posting this, I was under the impression that each project had tasks of widely varying difficulty. I do have the work cache set low (I think 0.1) because the machine isn't on very long each day. And yes, I know it shows how much of a geek I am that I have a dual-core laptop pretty much dedicated to playing MP3s while I go to sleep...    ---------------------------------------- [Edit 1 times, last edit by GraffBayCity at Dec 9, 2009 5:23:00 PM] |

OK, this is very odd. I was looking at the BOINC client last night and all the HCC tasks were set to take 25+ hours to complete and 2 had already missed the deadline. :( Based on this, I'll go with one of the projects that's setup to be a set run-time.
----------------------------------------Question - I remember there being more posts in this thread than are currently being shown, and one of them had in the names of projects that took a set amount of time. What happened to them??? (LOL - looks like I'm talking to myself now - first 3 posts are all from me.) ---------------------------------------- [Edit 1 times, last edit by GraffBayCity at Dec 11, 2009 6:54:00 PM] |

Deadlines are 10 days so I don't see how you could miss that with a .01 cache??? Have you double checked that setting? Are you using local preferences or the settings on the web? If you ever set anything in local it will override your web settings. If you want to go back to web settings you will have to open the local preferences dialog box and click the clear button.
