Hi everybody,
I am running BOINC client on two different machines (both WinXP Pro - just to mention), only one capable of CEP2 hardware requirements. Is there some automatic selection of tasks per hardware or how can I manually prevent the "weaker" machine from acccepting CEP2 tasks? Thanks a lot, rootman |

Create separate Device Profiles for each machine here http://www.worldcommunitygrid.org/ms/device/viewProfiles.do and set different projects under each of them.

 Branjo is almost right. Use My Grid - Device Manager to give each computer a different profile (Home, Work, School) then set Project Specific Settings Number of workunits per host for The Clean Energy Project - Phase 2? to 0 on the profile that should not run CEP2. Do not be fooled by Projects, which are only shown on your profile for your information. They are set by the My Grid - Projects command and do not change for each different profile. Hope I make sense. Sometimes my explanations are confuding. Lawrence Added:  This won't work. Fortunately SekeRob posted the trick that does the job.

Hi *,
thanks a lot. I tried it with two different profiles. Tomorrow I can tell whether it worked. :-) rootman |

There's a secondary trick, in case the backdoor "If there is no work for... send me something else", meaning anything is selected in the device profiles, to make sure the client wont idle when the favorite project(s) has/have no work: Set the permitted memory use/idle both lower than the CEP2 requirement... think WCG checks for 750MB free before sending a CEP2 task [though the system requirement page specs 1GB]. No other WCG science comes even close to that value.
[OT] 'Confuding' is probably a contraction of 2 other words... an Archie Bunkerism... could it be confusing and refuting? |

Hi branjo,
Oops! I can't set it to 0 either. So what is the answer? I do not think that Projects can differ from profile to profile. SekeRob's trick is the correct way to do this. Lawrence |

In the device profile, under available projects, deselect (uncheck the check box) by the CEP2 project; and deselect "if no tasks available". That will keep you from getting any CEP2 tasks.

As an opt-in project it should never be allowed to send results simply on the "if not tasks available" option.
----------------------------------------I understand that it does indeed do this and have deselected receiving other tasks simply because my network cannot handle multiple devices attempting to upload CEP work. In my view, it is a bug in the distribution although the techs probably view it differently. Maybe adding a "0" option to number of tasks would be a better way to work this for those who are less computer literate than setting a maximum memory.
