1) Message boards : Number crunching : Strange deadline management (Message 1456)

Hi

I have a task that ran for more than a day that then got suspended by another task because its deadline is shorter and boinc decided that the 2nd one needs to run in priority :


Is this normal ?

There is no risk that the suspended task gets rejected by the server if the new one runs for too long ?

Thanks

This one apparently crashed after more than one day of crunching : I think the computer rebooted because of forced upgrade on the machine (corporate policy, if you are not in front of the machine you have no action to prevent it...) but the checkpoint mechanism of yafu didn't work then ?

It's a pity...

Most of the antiviruses allow to exclude some folders from scanning in their settings, to avoid reporting false positive (and blocking apps, like boinc) --> add boinc data folder in there.

Boinc apps never include malware or virus, ask Berkeley why - or better read the well documented wiki pages regarding boinc security of applications.

At my side I have this task that started to crunch on 16/02/2018 11:13:03, I think it has been "100%" since 2 days, it's still running and "doing stuff" (see logs updating in the slot, progs crunching in memory)

19/02/2018 16:49:45 v1.34.5 @ FRHD-L509624, nfs: commencing lattice sieving with 4 threads
19/02/2018 17:28:18 v1.34.5 @ FRHD-L509624, nfs: commencing lattice sieving with 4 threads

deadline was yesterday morning.

I let it crunch since I can see it's doing stuff, but I report it because you mentioned it was useful.

Thanks for the (quick and clear) answer.

Hi

it may have been answered here but I couldn't find it, what is exactly the difference between app "YAFU 134.05 (mt)" and app "YAFU-4t 134.05 (4t)" ?

I get both of them on my i5 and the WU names are very similar, and I can't find a difference the way they are running : all the core are used, there are phases with 4 threads (ECM or <something else>) and phases where yafu.exe is running 4 cores, or only 1... (or maybe I didn't look close enough and I got confused ?)

Thanks

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...

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.

Mmmmm... it terminated around midnight, after more than 30 hours of calculation... the 2nd I had in queue then started... and terminated after less than 30mn !!!

What the hell with this project, on the computer I'm trying to run Yafu, Boinc cannot access internet (proxy restrictions), I move WU manually via USB key from my home computer, next contact with Internet will be tonight, so I don't even know if those 2 WUs will be validated (both had deadline this morning 9am)...

Hi

I have this WU that has now over 25 hours of computation, it is using CPU and processes are regularly started / stopped on the 4 cores, the logs in slot directory all show that there is growing activity done by the WU (factor.log, out file, etc) however the progress % is 0, there is no remaining time displayed (---) and the deadline is tomorrow morning...

Is it normal ? what should I do ?

Thanks.
