	My details for Application details has changed from "Max tasks per day" of about 120 to: SETI@home Enhanced (anonymous platform, nvidia GPU) Number of tasks completed 1471 Max tasks per day 1567 Number of tasks today 570 Consecutive valid tasks 1467 Average turnaround time 7.50 days And the computer has downloaded about 370 tasks in the last hour or so. The bad news is, I have never has the flops adjustment in my app_info file, but I have now got tasks with expected completion time of 01:23. The fastest VHAR on this slowish computer is ~8:00.

	Additional news is that these tasks with 01:23 completion time are not all VHAR tasks some at least are mid range AR = 0.4xxxx

	Additional news is that these tasks with 01:23 completion time are not all VHAR tasks some at least are mid range AR = 0.4xxxx Divide the estimate by the Duration Correction Factor, then multiply by 10 to get the allowed amount of crunch time before the task will be aborted by the core client. With my modest hosts, if I saw grossly underestimated work I'd be easily able to modify the <rsc_fpops_bound> for each such task to allow enough time to do the work. For those with much more throughput, there are likely to be too many tasks to handle by manual editing. Replacing all the rsc_fpops_bound values in client_state.xml with 2.5e15 would work[1], though. That's about the unadjusted bound for the longest-running MB work. As that bound is intended simply as protection from corrupted applications or such, making the change does not harm the project in any way. OTOH, if an app did happen to get into a loop, it would be a long time before BOINC would kill the task. [1]When reading xml files, BOINC uses a standard conversion to double for numeric entries. So editing to <rsc_fpops_bound>2.5e15</rsc_fpops_bound> will be read correctly. When BOINC rewrites the file it will become <rsc_fpops_bound>2500000000000000.000000</rsc_fpops_bound> simply because that's the way BOINC formats xml output of such values. Joe

	My details for Application details has changed from "Max tasks per day" of about 120 to: SETI@home Enhanced (anonymous platform, nvidia GPU) Number of tasks completed 1471 Max tasks per day 1567 Number of tasks today 570 Consecutive valid tasks 1467 Average turnaround time 7.50 days And the computer has downloaded about 370 tasks in the last hour or so. The bad news is, I have never has the flops adjustment in my app_info file, but I have now got tasks with expected completion time of 01:23. The fastest VHAR on this slowish computer is ~8:00. The reason you are seeing such low estimates is the "DCF squared" transitional problem I wrote about in April, and recently re-posted on these boards. Basically, the server is now applying your DCF value (of about 0.17, I guess) to the tasks before it sends them to you, in anticipation that your local DCF is close to 1.0 But until you work far enough through your cache for the first "short-estimated" task to complete, your local DCF won't adjust. Perhaps the simplest change you could make would be to give it a helping hand, by setting local DCF to 1.0 - that would stop additional downloads in their tracks (BOINC would finally realise that you've got enough work), and let EDF handle any VHARs that needed the hurry-up call.

	Before I went out I did increase the DCF to 0.2 from 0.05 and set to NTT, which was enough to send it into high priority mode for the gpu. It has done 41 tasks since then, and set the DCF to 0.89xxxx. Which has now increased to completion times to about 4 times what they should be for the new MB tasks and about 25 times what it should be for the old MB tasks and the AP tasks. So everything is in panic mode. This does nothing to help the main problem I will run out of AP tasks for the cpu by 12:00 UTC tomorrow. Another thing that is utterly stupid is that on the gpu it is going to have to crunch all the tasks downloaded since this f*** up first. Then it is going to process all the older gpu tasks that is going to reset the DCF back to it's old value. And it is going to . . . . . . . before disappearing up its . . . .
