Message 1063 - Posted: 1 Oct 2017, 11:12:50 UTC

I keep getting 4C tasks that say 21 minutes needed. They go well till about 99%, then go slower and slower, eventually reaching 100% and sitting like that overnight (but with task manager showing all 4 cores in full use). Often this makes the task go over the deadline.

Are these tasks broken or will they finish eventually?

If they go over the deadline, is the deadline extended if they're already running?

Let them run.
The progress indicator and remaining time is some kind of artificial intelligence of the BOINC client. The yafu application itself deosn't has any progress indication.
You will get credits up to 10 days after the deadline.

The admin said they are still running when they are done you will start new tasks, the 'finish time' is just a guess by the Boinc software and only after a few hundred or even a few thousand workunits will it be even somewhat close to reality.

So even at 100% for 20+ Hours allow them to Complete?

Message 1093 - Posted: 17 Dec 2017, 17:48:24 UTC

I have this WU running for less than 10mn and with less than a minute of reported CPU time, and then this one running for almost 3 days that I finally canceled : I had to suspend it / stop the computer, when I restarted it had lost all the running time and went back to 16 hours, and then I let it run for almost 2 days before I canceled it and now it says 1d18 hours running and less than 16 hours of CPU credited... this is all nonsense and very poorly managed : the cruncher needs a precise information on run time estimate and deadline, it is not boinc that "invents" runtime but the application that provides information to boinc about it's internals, we don't want some WU "working the time they want" and "deadlines that mean nothing don't worry".

Crunchers deserve a little more respect than this, I'm giving my CPU power and I pay the energy to run it, I don't like to be treated as an ignorant kid and "you don't need to understand that" kind of behavior.

Workunit runtime is not predictable. Each workunit is predicted with it's worst case. But very often it runs much faster because the different trial factoring method which are tried at the beginning. Out of this the BOINC client calculates some artificial remaining runtime.

So I should let the below tasks run or abort them, going on a week running now?
Seems a lot of waste of power for such a Long time for this.
My Cost is now what I am looking at because the two computer are really doing nothing.

2 Each YAFU-16t v134.05 (16t) windows_x86_64 going on 6 Days now
99.99% 1 second left resets to 99.98% back to 1 Second left on one task for 4 Days now
99,94% 23 Seconds left resets the same and been doing this for over 3 Days now
http://yafu.myfirewall.org/yafu/results.php?hostid=23988&offset=0&show_names=0&state=1&appid=

1 Each YAFU-8t v134.05 (8t) windows_x86_64 going on 4 Days 11 hours now
99.99% 3 seconds left reset to 99.98% back to 3 seconds left and this has been going on for 3 days now.

If the files in the slot are still updating and still consuming CPU, than the jobs are still running.

It is very difficult to participate when you use a windows machine where boinc cannot access internet most of the time (I use a USB key once a week to move WUs to a connected win VM in my Mac).

I've had the machine exceptionally at home for a few days (thanks to the snow in Paris :) ) so I could let it run connected to the net (out of corporate network) so I decided to give another try with yafu, I got a very short WU first (3 secs of run only !) and then I have one of those long ones that already reached 100% and is running, I can see the logs are updating in the slot, apps running in memory so I know "it's OK" but what worries me is that if it doesn't finish by Monday morning (and the deadline is tomorrow afternoon), that machine will go back to the office with no connection for boinc.

Supposing the WU then finishes during the week it won't be sent back before the next week-end so who knows if it will still be considered valid and accepted by yafu...

Ben non Jerome !!!
Entretemps, vous l avez surement remarqué.
Le delai actuel pour renvoyer le resultat est de moins de 48 heures sur ce projet !!
De plus beaucoup de contraintes
Si vous cherchez des credits : Collatz et PrimeGrid sur GPU
Sur CPU : CitizenScienGrid (long, mais beaucoup de credit .
PrimeGrid aussi en CPU

Tout les chiffres cidessous sont basés sur ma plateforme de reference : I7-2600K-16RAM-GTX950

So I have an 8t WU running which has now clocked up 16hrs but the deadline is 19/03/19 and it's been at 100% for quite some time now.
What happens if it gets past the deadline? Have I tied up 8 cores for 16hrs for nothing?
I won't be impressed if that's the case.

You will get credits up to 5 days after the deadline.
If the process still consumes cpu, it is still running. In this case there should be also file modifications in the slot directory. At least the file nfs.dat is updated roughly every hour.

Which files should be updating?

I have a small composite WU that has over 41 hours up now, using all 6 cores, but can't see any file that has updated in the Slot directory since the WU started.

You can oder them by time stamp and see which files are updating.
It should be factor.log and later nfs.dat.

OK, thanks yoyo,
but the only date stamp in the factor.log file is the original setup date and time, nothing has been added since the 16/3/19.
Even though it is using all 6 cores and has now reached over 49 Hours, I am going to abort it as it is not doing anything apparently, at least by the log file info anyway.
Sorry but this will have to be re-issued.
