Tried literally everything, setting the OS to max, telling the Centrino Duo laptop is a Desktop, forced the CPU to stay on 10x multiplier, as else it would switch down to 6x multiplier, but the sciences are just getting tops 30% of the spare idle time, the System Idle Time tracker clocking about 60% overall of doing nothing. SO, how do I tell Windows 7 to give full idle cycles to the sciences, not only WCG. All projects suffer this faith as was tested on QWMC and Docking@home.
----------------------------------------Nobody at the BOINC dev. forums has come up and proposed anything but getting the "we'll tell the developers". W7 has been out for a year now and RTM for over a month and seemingly no one in the BOINC world is seeing this... except some members reporting very long wallclock/elapsed times, where the CPU times are reported to be normal. Are they on W7 too? Anyone? PS, changing "nice" i.e. the priority manually does nothing since the sciences are hardcoded to run at lowest priority. 30% of 60% (6x multiplier) is 18% or 80% of the spare crunching power is going to waste if one is not aware. Mind you the laptop runs very cool.

No Win 7 boxes here but I am assuming the threadmaster GUI probably doesn't work in 7 as the registry has been changed since Vista? That's the only thing that pops into my head for now.
Have you tried running a virtual machine with xp installed to see if that would use full resources? PS congrats sek on the 15000+ posts |

The machine has no TM or anything. Temp is 46C so don't consider a thermal throttle is kicking in and when doing heavy normal priority stuff the CPU load does go to 100% and the multiplier along to 10x according CPU-Z.
----------------------------------------Just have RMclock to lock the multiplier to 10x, else it falls immediately back to 6x. Because of this the HFCC jobs been running 47 wallclock hours, and only 15:27 hours in recorded CPU time. The graph is constant i.e. smoothly running at just under 30% loading of the core. edit: falls not false

Sek,
----------------------------------------I'm running 3 machines with Win 7x64 as dedicated crunchers. I too was seeing a pretty big difference between wall clock and CPU time. After doing the following, they're now pretty close to being the same. (Always going to get SOME overhead, but it's now less than 1% difference). Control panel->Add/Remove Programs->Turn Windows Features On or Off Remove the checked boxes for Windows Media Center, Windows Media Player, and Windows DVD maker. I also removed other check boxes for things that weren't required for this machine to be a dedicated cruncher, up to you to decide what else if any you want to keep installed for you individual needs. Reboot. I then set the power plan to Max Performance and installed bonic with no screen saver option, no run as service, but yes to allow all users to control. Been working great here ever since. Hope this might help. |

Please don't shoot me, but since you have not written it explicitly: I presume you have triple-checked the throttle setting in the right profile and/or the local prefs?
----------------------------------------Otherwise I can only imagine one of those silly things that MS likes to introduce to "help" us without telling us, something like "we will limit the CPU that all these background processes can use so that the user is not bothered by them**". Next step being "where the h*** have they put that silly option so that I can disable it?". Good luck Sek. Jean (still a happy XP3 user for a while  )Edit: Variant: "...so that our bright power saving feature is not defeated by them.") ---------------------------------------- [Edit 2 times, last edit by JmBoullier at Nov 23, 2009 3:28:40 PM] |

@HutchNYC
----------------------------------------The Desktop with W7-64 Q6600 runs like a dream. About 99.8% efficiency. Credits grants went up from average 15.57 under old Vista-32 to 18.8 under W7. @Jean, to quote myself: The graph is constant i.e. smoothly running at just under 30% loading of the core. quadruple check now... unless BOINC now has a millisecond level throttle. Just need to find what that new feature is and hiding where. I've read a designers report by Mark R. laying out what they were doing to have idle processes to be truly treated as idle, even talking of concentrating them all so 1 or more cores could be put to sleep. I've even played the affinity to make sure they do not end up on 1 core. The taskmanager very clearly shows a flatliner for both cores near the 3/10th mark. Suspect it to be something similar to what I've read that happened to either Linux or Mac crunchers... an MS Rip.

A Great Many Thanks joneill003 for giving me ideas. I installed ThreadMaster GUI, set the sciences to 80 percent (40 for a dual core) and the floor to 50% (25 for a dual core), applied and... it proofs that nothing at all much in intelligence has changed under Windows 7. Running 80% on both cores now at 60C per CoreTemp. Next up I'll set it to 100%, and let TThrottle cut the allotted BOINC time down again so that it will never run warmer than 60C, summer or winter.
----------------------------------------Now I'll apply for a MVP diploma at MS... Microsoft Voodoo Practitioner.
