Hello

have 8 WU's looking like they will never end... ? (running since 10 up to 14 hours)

What was the runtime before?

Since yesterday we are cruncing on the fifth target: https://www.sidock.si/sidock/forum_thread.php?id=97

Please note that these new workunits can run five times as long as the old WUs, so it seems pretty normal to me. These are just way bigger WUs.

My tasks have gone from 2000-3000 sec to 17000-20000 sec. Credit increased too so it's not all bad!

Maybe it is a good time to think about breakpoints?
If it is not already implemented,that is.
Sorry, i ment checkpoints.

most of my results are too round 22000 seconds
my highest run time so far was 38000 seconds (more than 10 hours)
https://www.sidock.si/sidock/workunit.php?wuid=6927206

so a deadline with at least 3 days would be very helpful

and for this run time longer than 2 hours I would too like to have check pointing on the results

I had 20 hours on a slow PC, much shown as a few minutes time remaining.

My 4GHz i7-6700K Windows 10 system limits BOINC to using 7 CPUs. It downloaded 14 of the corona_Eprot tasks yesterday, with each of them having a 48-hour deadline and a 70-minute runtime estimate.

The first task took 9 hours, the second 9.5 hours. The deadline is now less than 16 hours away, but Boinc doesn't recognise there's a problem because the estimated runtime (calculated using the workunit's rsc_fpops_est value)
is out by a factor of at least 8. I'm expecting some of the 12 pending tasks to miss their deadline and others to be cancelled by the server because they haven't been started before their deadline.

Next bunches of tasks will be created with increased value rsc_fpops_est.

nothing changed. processing time is set to 40 minutes, and the job is running for 2 hours or more

Were they re-sends?
I had several re-sends from time-outs/no replies/aborts that had old short estimate.
Now got some with longer estimates.

now it’s much better, of course, but not as good as rosetta@home.
If 8 hours are assigned to the task, this will be the case (+- some minutes)
sidock is not so accurate - they plan two hours on a job, but it actually works four
doesn’t that interfere with the other projects boinc scheduler’s work ?

It goes the other way with me on two Ryzen 3950s. They run between 5 and 6 hours, but the estimates are 9 hours on one machine, and 12 hours on the other.
They should be converging to the correct value by now, but are correcting more slowly than usual.

Hi folks!

Estimate execution time, displayed by BOINC client, computed by it in last several days, may be two weeks and number of estimated flops for task. After increasing rsc_fpops_est in 2.5 times estimated time on my Ryzen up top ~09:45:00, but real execution time ~ 05:45. But, I think, after several days estimate time will be close to actual.

i have one more question, perhaps off topic.
why the tasks are reset after stopping, and do not start from the moment where they were interrupted ?
rosetta do so

because the WUs have no checkpoints

Yes, they have converged to 7 hours on one Ryzen 3950X, and 8 hours on the other, which are much closer to the actual time of about 5 1/2 hours.

And, some tasks, as usual can be computing longer than others. But credit is also larger.

Just aborted 62895949 after nearly 12h CPU runtime and showing 45% progress.
WU's come in showing a runtime of 5.5h. I would like to see the expected runtime somewhat more accurate if WU's run normal.
There seems to be quite a big spread in runtimes. Other projects are more predictable.
