Waaaaay off. While we're thinking about the wider principles, could we apply a band-aid to staunch these massive server over-allocations, please? Another example: Simap requested work first, but with a DCF of 0.70, the client calculation of the amount allocated was below the amount requested. Even after the 4-second completion of the NumberFields, DCF was still 35.52 So the request for 69736 seconds of work (under 5 hours, for this quad-core) resulted in an allocation estimated at 2510769 seconds: that's enough to keep all four cores occupied for over a week, according to client calculations. Since project deadlines are exactly 1 week, NumberFields went into immediate High Priority on all four cores, locking out all other projects until things settle down a bit. That doesn't count as "play nicely with other projects", in my book - but it's the removal of the DCF adjustment from the server code which is causing it, not any fault of the project. 09-Nov-2011 14:18:35 [NumberFields@home] Starting task wu_12E10_SF157-1_Idx6_Grp14124of41476_0 using GetBoundedDecics version 202 09-Nov-2011 14:18:39 [NumberFields@home] Computation for task wu_12E10_SF157-1_Idx6_Grp14124of41476_0 finished 09-Nov-2011 14:18:39 [NumberFields@home] Starting task wu_12E10_SF157-1_Idx6_Grp13897of41476_0 using GetBoundedDecics version 202 09-Nov-2011 14:18:42 [NumberFields@home] Started upload of wu_12E10_SF157-1_Idx6_Grp14124of41476_0_0 09-Nov-2011 14:18:46 [NumberFields@home] Finished upload of wu_12E10_SF157-1_Idx6_Grp14124of41476_0_0 09-Nov-2011 14:18:54 [boincsimap] Finished upload of 20111101.952163_1_0 09-Nov-2011 14:18:57 [boincsimap] [sched_op] Starting scheduler request 09-Nov-2011 14:18:57 [boincsimap] Sending scheduler request: To fetch work. 09-Nov-2011 14:18:57 [boincsimap] Reporting 1 completed tasks, requesting new tasks for CPU 09-Nov-2011 14:18:57 [boincsimap] [sched_op] CPU work request: 34402.22 seconds; 1.00 CPUs 09-Nov-2011 14:18:57 [boincsimap] [sched_op] NVIDIA GPU work request: 0.00 seconds; 0.00 GPUs 09-Nov-2011 14:19:01 [boincsimap] Scheduler request completed: got 5 new tasks 09-Nov-2011 14:19:01 [boincsimap] [sched_op] Server version 611 09-Nov-2011 14:19:01 [boincsimap] Project requested delay of 7 seconds 09-Nov-2011 14:19:01 [boincsimap] [sched_op] estimated total CPU task duration: 27270 seconds 09-Nov-2011 14:19:01 [boincsimap] [sched_op] estimated total NVIDIA GPU task duration: 0 seconds 09-Nov-2011 14:19:01 [boincsimap] [sched_op] handle_scheduler_reply(): got ack for task 20111101.952163_1 09-Nov-2011 14:19:01 [boincsimap] [sched_op] Deferring communication for 7 sec 09-Nov-2011 14:19:01 [boincsimap] [sched_op] Reason: requested by project 09-Nov-2011 14:19:03 [boincsimap] Started download of 20111101.955716 09-Nov-2011 14:19:03 [boincsimap] Started download of 20111101.955743 09-Nov-2011 14:19:07 [NumberFields@home] [sched_op] Starting scheduler request 09-Nov-2011 14:19:07 [NumberFields@home] Sending scheduler request: To fetch work. 09-Nov-2011 14:19:07 [NumberFields@home] Reporting 2 completed tasks, requesting new tasks for CPU 09-Nov-2011 14:19:07 [NumberFields@home] [sched_op] CPU work request: 69736.27 seconds; 2.00 CPUs 09-Nov-2011 14:19:07 [NumberFields@home] [sched_op] NVIDIA GPU work request: 0.00 seconds; 0.00 GPUs 09-Nov-2011 14:19:09 [NumberFields@home] Scheduler request completed: got 19 new tasks 09-Nov-2011 14:19:09 [NumberFields@home] [sched_op] Server version 613 09-Nov-2011 14:19:09 [NumberFields@home] Project requested delay of 21 seconds 09-Nov-2011 14:19:09 [NumberFields@home] [sched_op] estimated total CPU task duration: 2510769 seconds 09-Nov-2011 14:19:09 [NumberFields@home] [sched_op] estimated total NVIDIA GPU task duration: 0 seconds _______________________________________________ boinc_dev mailing list [email protected] http://lists.ssl.berkeley.edu/mailman/listinfo/boinc_dev To unsubscribe, visit the above URL and (near bottom of page) enter your email address.
