FAIR, it's a personal preffed procedure. There's no need to uninstall the old first, just install [upgrade] over.

Done the dirty today: Since WCG distributes a mix of GFAM : DSFL in a ratio of 1.75 : 1 (total computing time), I've set all clients to process an even number each, so e.g the quad has a <max_concurrent> of 2 for both and the duo a <max_concurrent> of 1. Buffer set to 2.5 days. Will observe when the ship sands... when there's so much GFAM buffered, so few DSFL, that cores start idling (Client stops asking for new work because buffer is full). Power to the cruncher... let us decide the weight, just as we do when a client is set to 100 : 100 Resource share for Project A : B. Mixes tend to improve efficiency... less competition for the same CPU bits.

An interesting post, Rob!
WCG distributes a mix of GFAM : DSFL in a ratio of 1.75 : 1 Are these numbers available somewhere for mere mortals to see? I presume the techs change them from time to time, so that leads me to assume "No", but I can still ask! Mixes tend to improve efficiency That could very well be true, but since GFAM and DSFL are both VINA-based projects, I would have thought the effect rather less in this case. Nevertheless, I'd love to see your numbers if you are (or have been) measuring this effect. |

The measurement is done on My Grid. Day X minus day Y taking the difference for the both. Taking each day a snapshot and then the sheet auto computes the various distributions, progresses and shares. Not so much interested in results or durations, if one is faster, then the slot vacated by a task completion will be taken by a new task of same science.
Yes I know it's both VINA and thusly fairly same, but, the apps work on different libs with different parms. It was though meant as a general observation, more gain achieved e.g. with the quite differential HCC and VINA apps. One of these days, BOINC [servers] will monitor performance and steer what gets send... knreed once gave me a link to a paper discussing this and had passed this to Dr. A at Berkeley. Things we dream of, and likely only beneficial to umbrella grids and in an environment where users accept automated optimization, and not points, ranks etc as the leading guide [An option on device profiles if you want it :O]. Not an environment for the MMers who 'always' know better than BOINC does, without exception ;) |

Rob,
As always, you're demonstrating your zeal for crunching the numbers from the crunchers  . Thanks for the details. |

'Doing the Dirty' continues on all devices and the situation is becoming gradually grave: The app_config.xml is set to allow 50:50 and the GFAM caches are building, whilst the DSFL is depleting... the moment that cores start idling is not far off. The cache totals per BOINCTASKS are:
Duo: GFAM 1 day, 14 hours for 4 tasks DSFL 17 hours for 2 tasks Quad: GFAM 8 days 12 hours for 44 tasks DSFL 1 day 5 hours for 9 tasks Hexa (2 cores disabled for crunching... heat, though dedusted thoroughly and it's only May 10) GFAM 9 days 7 hours for 33 tasks DSFL 4 days 3 hours for 14 tasks My guess is that idling and intervention [flip flopping profiles] will be needed in 36 hours. Meantime the running ratio with the app_config max_concurrent control has improved from 1.75:1 GFAM/DSFL to 1.58:1. or 76 days crunched for GFAM and 48 days for DSFL since start of measurement. |

Rob, speaking of buffering, I'm trying to find the post that describes the change to min/max buffer in BOINC 7 but not having luck. Thought it was in the FAQ. Would you happen to have a pointer?

You may remember I introduced the MinB AND MaxAB acronyms in that thread, so add me as author [BOINC Support forum it was in as well] and voilá, in this search, second, fifth-to eighth item on the list: https://secure.worldcommunitygrid.org/forums/...=0&sort=1&rows=20
Hope it helps to white the gray a bit. |

Just download the new version and it seems i cant get a gpu wu to analyze . Why is that happening and how i can enable my i5 internal gpu to work together with my discrete one ?
----------------------------------------Thanx in advance *i dled new nvidia + hd 3000 drivers before 10mins... still no luck on working :( |
