1) Message boards : News : Should the fixed credits be higher? (Message 2833)

I agree with kraDen and Ron and Zombie at the same time :)

Many people don't crunch for credit BUT credits are the only "reward" that a boinc project can give to its volunteers.

So unless you are a "big, old and well established" boinc project, and can basically "not care too much" about credit, it is still an important incentive to get new crunchers, and keep the one you already have :)

I don't like over-crediting for that same purpose, it's not a good philosophy, but under-crunching is worse, IMHO.

I now have a number of "Get Decic Fields v2.09" running for several hours and all seem fine so far.

Thanks for the quick and effective fix.

Hi

I have loads of WU that crashed with signal 5 error on my Mac :

There are all "Get Decic Fields v2.08".

The "Get Decics with Bounded Discriminant v3.05" are running fine.

I find *very* strange that a path to a library may be /Users/eric/BOINC_Project/Pari/ don't you think ;-)

When you look at any project server status you actually never know if the WU available (there are plenty for the moment on NF for both applications) are available for any platform, or just some...

Hopefully !

I'll see when I get the next WUs - eventually I won't see it if they work OK, I run many projects at the same time (the most I can ! :) ) so if all goes well as expected I may not notice it.

Thanks for the update.

Thanks for your quick answer, hopefully Gred has some other idea.

Just one more thing : I had another WU failing this morning, alone (it was the only numberfields WU running by that time). In the meantime I had some leiden, lattice, rosetta, citizen science grid, seti and WUProp WUs that terminate successfully.

So the issue may be related to *my* machine and some other people machines (since this thread was not started by me) BUT it has to do with the way numberfields application is coded, some instruction it uses that interacts badly with my system and causes its failure.

If you google "process got signal 4" you'll find some entries with seti (2011), malariacontrol (2006), milkyway (2008), lattice (2014, me ! they never answered anything)...

I found a very interesting post on eOn forum (2013) regarding a "process got signal 8" error and someone (admin ?) answered "The signal 8 error means " SIGFPE 8 Core Floating point exception" and is project-related. I have edited my input parameters handle this error and have not had such an error has not occurred since." So maybe it's not the same issue but I read "edited my input parameters handle this error", what does it mean ? maybe somehow the same kind of "parameter setup" can be done do "ignore" it ? or was this the project who meant that he dealt with this error in the eOn application code ?

Hi

I just got 5 WUs crashing at the same time on my iMac with that weird signal 4 error. Bad thing is that 4 of them had above 14 hours of crunching...

I have experienced that same crash with other boinc projects in the past, not very often but on a regular basis, I mentioned it on projects forums, and never got a clear answer from any project admin (some of them did search).

The very weird thing is that when this happens, all of one project WUs crash at the same time, but it won't affect other projects running at the same time - I have an i7 with 8 WUs of various projects running at the same time, 24/24 7/7.

Those who answered me kn the forums said "it has something to do with your Mac, look in the system logs", which I did trying to figure out in the Mac console some event happening at that precise moment. Unfortunately I could never see anything obvious, I'm not techy enough to see that.

For example now I can see that before the crash I have many events like

06/03/2015 22:16:36,000 kernel[0]: RTS: Scan time-out on file '/Volumes/Macintosh HD/Users/Shared/BOINC Data/slots/7/GetDecics_state'


but they also happen all the time on other boinc WUs running at the same time

and just before the crash I see

06/03/2015 22:18:54,868 com.apple.xpc.launchd[1]: (com.apple.ReportCrash.Root[45493]) Endpoint has been activated through legacy launch(3) APIs. Please switch to XPC or bootstrap_check_in(): com.apple.ReportCrash.DirectoryService


then again some scan time out and then 5 crash reports are generated in 2 seconds, below is one of them, hope this can help in any way :
