How have you gathered 300 threads?!?!?! I have a LOT of computers. Running a bunch of them off-site where there's free electricity available to keep costs down. Here's my inventory: 24/7 crunchers, some see part-time use but usually not much: 7x Dell T5500 24/7 (3 with 2x Xeon E5520, 3 with 2x Xeon E5620, 1 with 2x Xeon X5650) = 60 cores / 120 threads 1x Dell T7500 24/7 (2x Xeon E5540) = 8 cores / 16 threads 1x Dell XPS 24/7 (i7 4790) = 4 cores / 8 threads 1x DP Opty 6238 24/7 = 24 cores / 24 threads 1x 4P Opty 6128 24/7 = 32 cores / 32 threads 1x i7 4700MQ 24/7 = 4 cores / 8 threads 1x FX8350 24/7 = 8 cores / 8 threads Total 24/7 systems = 140 cores / 216 threads Part-time: 4P Opty 6376 = 64 cores / 64 threads DP Xeon E5 4667 V3 = 32 cores / 64 threads i7 2600k = 4 cores / 8 threads AMD A10 = 4 cores / 4 threads i7 3930k = 6 cores / 12 threads i7 3770k = 4 cores / 8 threads 1x Dell T7500 (2x Xeon E5540) = 8 cores / 16 threads Another 122 cores / 176 threads |

We are running this project low priority at the moment, it is to allow us to monitor multiple new aspects of the backend system. We hope to have this running full speed in the future.
Thanks, -Uplinger |

We are running this project low priority at the moment,... Ah, Keith, I see you are reading my mind !!! I was just going to ask the 'priority' question because I have both OET and FAHB selected on my machine, but only seeing OET WUs. Thanks for the info. CJSL Crunching for a brighter future... |

At Techs: Is FAHB locked in as moniker or will it be FAH2 for project and fahb for app? Need 24 hours to create a new charting stream. Everything should be FAHB. Thanks, -Uplinger Why I need 24 hours minimum is because the first XML for the project stats page does not include the tags which give the 'yesterday' statistics. It would be nice if any xml, from the first day would include all the tags, with zero value if there's nothing. What happens is, day 1, generate a map for import, run stats and charts day 2, delete map and generate a new map with the 4 additional tags under the 'DailyStatisticsTotals' section, in the case of FAHB Date, RunTime, Points, Results 1-10-2015, 247607030, 12874915, 5045 |

OK, created a query map from your second day xml import.
WEB 1 https://secure.worldcommunitygrid.org/stat/vi...amp;projectShortName=fahb Selection=EntirePage Formatting=None PreFormattedTextToColumns=True ConsecutiveDelimitersAsOne=True SingleBlockTextImport=True DisableDateRecognition=True DisableRedirections=True All needs doing now is create a copy of the mapping file rahter than starting from scratch, change the ShortName tag and import this. Office was happy to accept this [in a one time test]. Will know on next project launch if this works or falls over, doubt it though as the exported map does not seem to include the tags, just says EntirePage. [/osot] |

Question :
10/2/2015 9:02:02 AM | World Community Grid | Tasks won't finish in time: BOINC runs 99.8% of the time; computation is enabled 99.8% of that I have 8 FAH2 WUs active and a few more in the queue. Unless my PC becomes disabled I calculate that I will have all WUs finished by the deadline. Why does this message appear? |

There's various dynamic control values that are used to every so many seconds recompute if the total work in buffer will be completed in time. Either your buffer is too high or the control values have degraded <on_frac> and or <active_frac>. For a 24/7 machine they would be near 0.999999. Part time devices have a lower value. For instance if 0.5 [12 hours a day] and your buffer is worth 2 full days computing, BOINC computes 2 / 0.5 is 4 calendar days needed. At that point you get "Tasks won't finish in time:..." for FAHB. The value degrades rapidly if e.g. powering off Friday and then restart on Monday and increases slowly again. It can take 10 days continuous crunching to get it back to 0.999999. On the other hand if your have a stable computing pattern, BOINC will automatically reduce the amount of work buffered.
----------------------------------------At any rate, let it run and things will balance over time. Edit: Theoretically the write down of the On/Active fraction values does not happen if a client is off for longer than 10 days. My Linux host with 7.4 client usually starts off with getting just enough to get all cores busy when launched after one month off and then slowly gets more the longer it is left on.

Since BEDAM/Impact is not VINA, how does the performance of Linux compare to Windows?
Would a 64-bit Windows version improve performance significantly over a 32-bit Windows version? |

There are known instances where 64 bit compiles are slower than 32 bit. If that was found in the case of BEDAM, why waste time on compiling 64 bit? OTOH, by having 32 bit only you get a more consistent result series. OTOH to the OTOH, there's as I understood no platform tying, homogeneity concern for FAHB i.e. one task can run on windows and the next in the series can run on Mac or Linux, which overturns the 32 bit point again as then 32bit generated steps can be concatenated with 64 bit Linux (and probably Mac too, think that's what it says on the system requirement page). I.e. there's a reason but not one Spock could logically reason without more input, Jim ;P)
