Hi,

Client: 7.14.2, Win10

started using the client yesterday. Also running folding@home in parallel (for GPU only if Rosetta is active). CPU is Ryzen, no OC. Got first batch of WUs which were processed and submitted, currently it is crunching other WUs, however, one failed with computation error at 100.000%, logs show:

24.3.2020 5:37:10 PM | Rosetta@home | Computation for task 8ft7da9j_3h3_design3_COVID-19_SAVE_ALL_OUT_902898_3_0 finished
24.3.2020 5:37:10 PM | Rosetta@home | Output file 8ft7da9j_3h3_design3_COVID-19_SAVE_ALL_OUT_902898_3_0_r1505128294_0 for task 8ft7da9j_3h3_design3_COVID-19_SAVE_ALL_OUT_902898_3_0 absent

so it did finish successfully but failed to write the output file and submit or...?

Thank you!

Usually, it's the other way round. If an application crashes, or otherwise ends abnormally, then it doesn't reach the code that writes the output file.

'Output file absent' is a sign that the app finished, but didn't finish normally - most often, a crash.

em, no, it didn't crash imho, I'm checking it periodically, would have noticed if client has disappeared. Also, would logs indicate a crash?
UPDATE: Event Viewer -> Windows Logs -> Application - no entries for that period of time

oh, I think you meant the separate process that was responsible for that specific task crashed. Okay, how do I resolve it then? Tried suspending and resuming that task from the client - nothing happens. It has 6:04 hours of elapsed time, sad it that's wasted.

The first line of the event log that you posted contains a task name, Rosetta has the 'task name search' feature enabled, which led me to Rosetta task 1131821072. That has the finish reason

Exit status	-1073741819 (0xC0000005) STATUS_ACCESS_VIOLATION

- which is actually a Windows code, not Rosetta or BOINC.

There is a brief report from the 'Windows Runtime Debugger', but it's much shorter than most I've seen - the fuller ones have a 'stack trace' towards the end, which is often the most useful part. Yours is missing.

I think you may have to write this one off to experience. You can look around the Rosetta forums to see if anyone else has reported this kind of problem recently, You can also ask there for advice - quote that task ID number above. Finally, keep an eye on Rosetta workunit 1019438559 - a duplicate copy of your task has been sent out to another volunteer. It sometimes happens that a data error causes a task to crash, and if that happens, all the other copies fail as well. At least that would give you reassurance that it wasn't your - or your machine's - fault.

Just looked at the client and couldn't find it, that task is nowhere to be seen, I think it disappeared:

well, anyway, it's gone now, hopefully won't happen again.

Thank you!

When a task finishes in the normal manner, it will upload the result of the calculations to the Rosetta project server and BOINC will report the task as being finished and finished correctly.
In your case the Rosetta science application crashed before it could finalize the result of the calculations, thus it had nothing to upload (output file absent), and BOINC then only reported that the task had finished in a faulty manner.

The task in question is at the moment of being reported no longer on your system, it will get deleted.

Thank you for the clarification! I'm new to this, jumped into running those tasks without much of background research :)

Hello I have the same problem with the same message.

Since yesterday I installed the client on two windows 10 PC for Rosetta@home. One is doing the job, the other is not completing anything. I have computation errors with problem of files. I found in a very old message that it maybe because of Visual C++ redistributable missing, so I installed it, but it was not that.

Did you solve your problem?

Received the same error on a docker image. Tracked down the issue to boinc not having permissions to write to disk.
Could this be a lead? "absent" meaning "I cant save to disk or send it anywhere, something is stopping me!" (Like a Firewall or insufficient disk space, permission errors?)
