----------------------------------------Any particular reason? Also if discussed elsewhere I missed it. ![]() |

HFCC WU size vary greatly, for my systems they range anywhere from 4 hrs to a max of 21 hrs (that I saw). Your system must of recently complete a few of very long WUs. Now boinc thinks that all WUs will take longer then normal for your system. I seriously doubt that all of your WU from HFCC are 25 hrs (unless it normally takes that long for you). Just let it run its course and the estimated time to complete them will be reduce accordingly.

MM,
----------------------------------------Yes you missed it ;-) Per Uplinger all jobs for a single compound are now cut into 2 parts just enough to be able to run them without having to recompile the software for more dockings per WU (I've counted 43 on several sequential jobs). This approach is regardless of the toughness so you can see jobs depending on device from 2-4 hours to 20+. And as anhhai noted, when completed job durations go up, the TTC estimates for the rest in the buffer follow... until enough 'normal' are run again to bring that value back down. TTC reflects current going actual average... going up fast in the client and only slowly going down... to protect those that like to run with big caches and than suddenly have a client running in High Priority mode. cheers

Thanks for the info guys.
----------------------------------------My concern is that I have a 3 day cache of work. This is on a dual westmere system.(8C/16T) I had a pair of slower L5630's(2128mhz) in there but today dropped in a pair of X5687's(Don't go looking for them, they don't exist..yet) ![]() Got smart and set for "Don't get new work" till my cache of work drops. Hate to see the machine get behind in getting the work done. Once again,Thanks for the info! ![]() |

The work fetch actually auto suspends till the buffered value drops back to below that 3 day objective. If you look in the message log and have the scheduling debug flag on you actually see for instance:
----------------------------------------Thu Sep 9 06:56:21 2010 WCG Requesting new tasks Thu Sep 9 06:56:21 2010 WCG [sched_op_debug] CPU work request: 133101.82 seconds; 0.00 CPUs Thu Sep 9 06:56:22 2010 WCG update requested by user Thu Sep 9 06:56:26 2010 WCG Scheduler request completed: got 8 new tasks Thu Sep 9 06:56:26 2010 WCG [sched_op_debug] Server version 601 Thu Sep 9 06:56:26 2010 WCG Project requested delay of 11 seconds Thu Sep 9 06:56:26 2010 WCG [sched_op_debug] estimated total CPU job duration: 139303 seconds Thu Sep 9 06:56:26 2010 WCG [sched_op_debug] Deferring communication for 11 sec Thu Sep 9 06:56:26 2010 WCG [sched_op_debug] Reason: requested by project Thu Sep 9 06:56:41 2010 WCG [sched_op_debug] Starting scheduler request Thu Sep 9 06:56:41 2010 WCG Sending scheduler request: To fetch work.

Usually just one call on a steady running and backfilling machine. The Y seconds lifts that cache usually over the 3 day requirement as no job exists to give the exact amount of work, so in the last call 8395 seconds were asked and 17413 worth were received. Good tool to follow cache size is BOINCTasks. In the Projects tab it gives a Per Core amount of time that is buffered, including the work already crunching. Now it shows 2:01:35 days per core where my cache is set to 1.9 days... just below that famous 2.0 days R++ rating level so repair jobs do come this way (of rare work) Crunching On :D

See this: http://www.crn.com/news/components-peripheral...wfbk-VBVRIzskg**.ecappj01 Cheers yes,seen the info. No more worries, Pulled the X5687's today and dropped in X5690's.. ![]() They won't show up on the charts as this machine is in Jon Magoon's name(loonym) He passed last Dec 28 from Bladder cancer. Some of us at XS forum are making sure he isn't forgotten and his account doesn't drop in the stats pages. It's a small thing but the only way I know to say we haven't forgotten you. ![]() |

Got another one going for 21 hours this time at 33% after 7 hours. Efficiency 98.5%, checkpointing at semi regular intervals. Snip log:
