Message 3658 - Posted: 30 Sep 2014, 7:27:39 UTC - in response to Message 3656.  
All GPU jobs which has finished, get's an error uploading/downloading the job. Status in BoincTasks 1.61 reports "Download Error"

Your posted log show only Download errors (so these can't be tasks "which has finished").
Do you also have uploading errors in the log?

(I don't have Upload errors, I only have this: (which is during Reporting, not Uploading)

The other problem with "Error while downloading" is that some tasks
which are already completed by someone
can't be done by anyone else so the WU ends with:
"Completed, can't validate"/"Too many errors (may have bug)"
http://asteroidsathome.net/boinc/workunit.php?wuid=20964261


As this is bad for the project (some WUs have no chance to generate results)
I sent PM to Kyong about the problem

(definition: WU = collection/sum of all tasks, in this case 10 tasks were sent/generated for this WU (but 8 were not received))

Some more WUs in this state (most from users which posted in this thread)

All have one task "Completed, can't validate"
and the WU ended in "Too many errors (may have bug)"

I had this sometimes recently but didn't know this was a more serious error until I looked up the message boards now.

Please check. Thanks!

Still failing and getting worse: 6 out of 8 failed.

Both SSE3 and CUDA55 WUs are affected.

There is no difference between "SSE3 and CUDA55 WUs", so if this happens it will happen with any 'type' of WU
(e.g. the same task you receive for SSE3 app someone else will receive for CUDA or AVX or ...)

Some of these 'Error while downloading' is yours, the other 8 are your 'wingmates' (quorum partners) - the same WU, 9 tasks:
http://asteroidsathome.net/boinc/workunit.php?wuid=21710924

Really bad is when somebody (me in the case ;) )
Completed the task but there is no other wingmate that can confirm the result
so the final outcome is 'Completed, can't validate' (after 9 Error tasks)

Pardon me, but SSE3 WUs are for CPU, while CUDE55 WUs are for GPU.
But I guess you meant that there is no difference in WU generation, right?

I just thought I should mention that both types are affected, so the problem can be found more easily.

I didn't have that myself (yet), but sure, that's quite annoying.
But aren't tasks with download errors be sent out again automatically?
If not, why not?

Houston, we have a problem.

I'm fresh out of tasks, each request for work comes back empty...
10/12/2014 11:13:28 PM | Asteroids@home | Scheduler request completed: got 0 new tasks
10/12/2014 11:13:28 PM | Asteroids@home | Project has no tasks available

...and there are only 19 tasks ready to send.

I mean that the same file you try to Download from the server 'for CUDA' (= to be processed by CUDA application), someone else will try to Download for CPU
So there is no difference in the WU file (if the file do not exist on the server = Download errors for everyone)

The only difference is that you will process the Downloaded file by CUDA application,
the other computer will use other application (for CPU or again for CUDA - depend what his BOINC asked for)


But aren't tasks with download errors be sent out again automatically?
If not, why not?

Click the links and see - the WU was "sent out again automatically" 10 times and failed on every attempt
(and the server gave up: 'Too many errors (may have bug)' - no more attempts will be made)

The webpage is cached, NOT a live page, so the "19" you see may not be a real number, just what was available the last time the page was updated. In your case it seems to in fact be zero. In fact the page now shows:

Yes, I've seen > 30% download failures for several days. Some fail immediately. And no tasks available for about 1 day. Server status are OK, but there's no work available.

I wasn't aware of that but thought that SSE jobs are always sent out as SSE and CUDA as CUDA. On the other hand, one could have guessed that it makes no difference so they get mixed up. Thanks for the info!

Yep, I've got 15 download errors already today (for 2 different computers). Total 173 on the list... from the recent days. Also there seems to be daily problems to upload results of completed tasks. Upload typically needs numerous retrys and takes time.
