Check with Richard Haselgrove

Check with Richard Haselgrove about your cpu.  I believe there is a documented issue with that particular cpu with BOINC.

I would say that it hung up on the task.

Knew I remembered an issue with that cpu.

And there are few such "starting from scratch" in the log.

Some checkpointing issue?....

No.

Arecibo, large tasks are bundles of 8 smaller tasks.  Each member of the bundle will "Start from scratch" at some point.

From the output in your first message, the error would appear to be:-

[13:48:40][9716][ERROR] Input file on command line
../../projects/einstein.phys.uwm.edu/p2030.20180911.G55.22+01.39.S.b0s0g0.00000_1524.bin4

doesn't agree with input file
../../projects/einstein.phys.uwm.edu/p2030.20180911.G55.22+01.39.S.b0s0g0.00000_1523.bin4

from checkpoint header.

[13:48:40][9716][ERROR] Demodulation failed (error: 2)!

Notice the 1524 <--> 1523 mismatch in the data file name.

If you were stopping/restarting processing by any chance maybe something got out of sync?

My guess is that the smaller tasks that are part of the bundle of 8 have that final sequence number changing by one for each small task.  It might be some sort of bug with how the stop/restart of processing occurs if it just happened to occur close to the changeover from one small task to the next.  Maybe you just happened to hit the jackpot :-).

 

Cheers,
Gary.

It's not an error really, it's just how BOINC reacted on task abortion via GUI.

I decided to abort that task cause it l ran more than 2 days of CPU time already and clearly would miss deadline.

 

Regarding batch of smaller tasks, thanks, I'll take this in account.

Regarding BOINC crashes & CPU - well, BOINC mostly works fine issue with particular type of app not with BOINC. I did many tasks on this particular PC it worked on SETI before now purely on E@h.

Currenly I just disabled this kind of work for this type of hosts (to not waste CPU time missing deadlines).

But if some debugging of possible issues with BRP large is needed I could enable work again and watch closely.

Thanks for the link, actually I completely forgot about that issue. But, looking at the thread, it seems Richard gave some advice, I did as he proposed and issue was solved... Since then host works fine... Perhaps it's smth another...

 

For completeness: currently host is running BOINC 7.16.5 (x64)

Yes, I would say it isn't

Yes, I would say it isn't worth it on that cpu.  I was amazed at how long the tasks take on that cpu.

I run both the BRP4 and BRP4G on my Jetson Nano and I do the BRP4 in ten minutes and the 4G in 1.4 hours.

No problem finishing them in time.

I suspect you will have more troubleshooting opportunities in a month or two down the road when we eventually get the new BRP7 tasks and applications.
