I've removed my 1 remaining XP machine from this project. Just not worth it for it to take 6.5 hours to crunch when the Win7 machine with the same hardware does them in less than 4 hours for the same amount of credit. Must be a 32/64 bit thing I guess.

went from 3 pages inconclusives down to only 4 wu's left.
crunching on 4 w-7 64 bit pc's completing wu's in 1.76 2.30 3.10 and arround 4,00 no incl since last breakdown.... |

I'm seeing the same pattern on my WinXP and Win7 x64 machines also.
----------------------------------------Hopefully we'll get some information from the techs regarding possible causes and/or resolutions. [Edit 7 times, last edit by AgrFan at Apr 24, 2012 2:40:43 AM] |

On this Win7 X64 laptop that's running TTrottle with CPU set to 50%, normally the WU completed CPU time is half that of the Elapsed time. But, these WU for this project the CPU time is about 25% that of Elapsed. Very strange indeed. Going to change TTrottle to 100% to see what happens. This of course will make the CPU run hotter.

Still no wu's? That may be a good thing since I got this yesterday: PG&E energy statement (e-Bills) information Amount Due: $606.73 Due Date: May 9, 2012  Utility CO-OP ? You'd be swimming in dividends.  Or at least your neighbors would be.  Yes co-op and haven't looked at the dividends lately so don't know, hmmm will have to now though! Yes some of the foothill communities have done exactly this. Unfortunately it takes a large group of people to be interested in doing so. Not likely to happen in my parts. I doubt I would get involved as the easiest way for me to drop to $50-$90/month is to deinstall BOINC 8 times. As I paid my bill I did some "finger and toe" math. Took an almost three-week period of time where I was only running WCG (no cards) and extrapolated it to 30 days (~ 200 wu/day). Divided that into 4/5 of my average electron bill. In very round numbers it costs me ~ 10 cents/wu. That is just my situation and I hope yours is better.  Oh good grief now you want me to do math TOO!!! Okay but it will take a few days, my wife is out of town and in order to control her spending she pays the bills and knows all of that kind of stuff. BUT I THINK mine is better...I am pretty sure I am doing well over 200 workunits per day on all the projects and pc's I am doing. I also use a gpu in every desktop, two gpu's in some desktops! My current Boinc RAC is almost 2 million according to here: http://stats.free-dc.org/stats.php?page=userb...e81490ce47752d88cb0cbd5be I don't know which one is yours as there are many Dataman entries. If you go to the top corner of the page I linked and put Dataman in the user box and press enter a list comes up, hopefully you can figure out which one is yours.   |

I'm seeing the same pattern on my WinXP and Win7 x64 machines also. Hopefully we'll get some information from the techs regarding possible causes and/or resolutions. Easy answer seems to be the double wide data path of the 64 bit over the 32 bit OS. However I am not seeing that difference on my Win7 32 bit and 64 bit machines, or my XP machine either for that matter. OS time credits XP(32 bit)---4.00 88.1 Win7(32 bit)---5.02 84.3 Win7(64 bit)---4.60 88.2 These are ONLY doing CS4W units for WCG but all machines are ALSO doing Poem and gpu units for Moo at the same time. All machines are quad cores of varying speeds but not overclocked. The XP machine has 3 gig of ram while the others have 4 gig of ram in them, the ram is not high speed or anything like that. The machines are Boinc ONLY machines so that is all they do. So could the answer be the amount of ram in the machine, not enough being the critical factor? |

I'm going to make some resource allocation changes today. Anyone still having problems with SWater?

CPU: 04:13:36 Hrs Elapsed: 19:11:52 Not understanding the combination of CPU set at 50% (what? CPU time or Cores?) and TThrottle. That could be working against each other, so would recommend 100% CPU time [if that's what you're restricting] and let TThrottle limit the CPU time through the chosen temp ceiling for maximum throughput at any part of the day [hot noons, cool nights] --//-- |

We are looking into the runtime differences for CFSW. It is not a 32/64 bit issue but XP is running much slower than Win7. At this point the cause is unknown but we are investigating.
Thanks, armstrdj |
