very buggy with variable runtime wu aka HCMD. Does confirm my thoughts that client side was being ignored for some "server side" logic. Thank you for the 80 wu per day limit else my SINGLE core CPU would have another 4-5 days to dig out of this hole, 1.5 day cache, normally 10-20 wu pulled 86 more before limit shutdown, next wu finished pushed DCF to 9 days, have not pulled a wu on this box for 4 days and have estimated 2 more days to go

Edit: appears that service side adjusting is only done on work request, not on reporting, as I am now over cached, I guess I will not know new dcf (per server) until client sees need to request work Yes, the per-application, per-host estimates in v7 is based on your validated results for application/host-combination, and starts taking effect after 10 validated results for application/host-combination. These only affects the estimates on new work, not work already downloaded on client. Having DCF on top of the server-estimates just means it takes much longer for things to stabilize, for 1st. the DCF is corrected, for so the server-estimates gets corrected, for so the DCF must re-adjust with the new server-estimates.

Hi Raul, If you have more than one computer, you can use the BOINC home, work, school, and default device profiles to make separations of WCG projects, with different queues on each.Unfortunately BOINC sees all WCG sciences as 1 pot, meaning if any task [Beta inclusive] runs for instance twice as long from estimate, BOINC assumes all other tasks to also run twice longer than estimate [your SN2S jobs in this case]. It will normalize again... we all need to allow for BOINC to give it time. That said, the high variability of WCG tasks, single sciences and across the board, does force to keep the task buffer low as else panic will break out. A 5 days cache suddenly can become 10 days cache by the estimations and then there's deadline trouble. Keep it no higher than 2 days and the issue will rarely crop up. cheers. --//-- Be careful. Once you have made project changes in the detail device profiles, don't make any project change to the overall project page. It would OVERRIDE this and put the same projects everywhere.

Hello retsof,
If you have more than one computer, you can use the BOINC home, work, school, and default device profiles to make separations of WCG projects, with different queues on each. Be careful. Once you have made project changes in the detail device profiles, don't make any project change to the overall project page. It would OVERRIDE this and put the same projects everywhere. Yes indeed, device-profile is one mechanism to separate or otherwise abstract a device for interfacing with other mechanisms/entities (projects, and hopefully later, per science-applications: GPU-based, CPU-based, beta?). As for the overall project page and to make the whole idea of separation/abstraction work, yes, crunchers have to ensure that they select/attach a specific profile-Name to a specific device-Name (and next clicked on "Save"), else the settings indicated in the overall project page (as Saved) would apply to the specific device-Name instead.-- snip from retsof [Mar 26, 2012 1:33:13 AM] post, italicization-emphasis mine. ; |
