Unfortunately, my 1012 has failed at the first trickle (here), just as the my 1008 did (here).

Might be a different cause but might be the same.

Batch 1012 will fail on Intel machines. Batches 1013 & 1014 should continue running.

I have a 1008 task (https://www.cpdn.org/result.php?resultid=22417298) that seems "stuck" - it's been at 6% and change for 6 days now while the rest of the tasks blow past it.

Windows 10 VM on an AMD system.

Is there any value to letting it continue spinning, or should I just abort it and let some other system try?

Rather than abort, could you please do me a favour? Open up Resource Monitor, click the 'CPU' tab and scroll down to find the 'wah2' list of processes. You should have 3 processes per task. For your task, n15e, please let me know how many you see. I think you'll only see one process: wah2_8.29_windows_intelx86.exe and not the wah2am_* and wah2rm_* processes. Can you confirm?

Also, if you know your way around the BOINC folder layout, would be great if you could locate the task directory and check a file for me. I'd like to see the last few lines of a file called 'stdout_mon.txt'. It can be found in the task directory, which will be under your BOINC install 'data' directory:
e.g. c:\Program Files\BOINC\data\projects\climateprediction.net\wah2_eas25_n15e_201212_24_1008_012272746_0\stdout_mon.txt
Note the 'data' directory under BOINC is usually a hidden directory, you'll need to unhide folders in file explorer.

The reason I ask this is because up to now it's appeared that only AMD PCs can run the 1008 tasks (though not produce correct results). It sounds like yours has crashed and I'd like to see how far it got.

After this, rather than Abort I suggest doing 'End Task' in Resource Monitor (right click on the correct process name). I *think* this will avoid your host being marked down for aborting tasks.

Many thanks.

I have 9 tasks currently running on the system (it's a bit short on disk, I should fix that).

I see 9 wah2_8.29 tasks, 9 wah2am3m2_8.29 tasks, and 9 of the wah2am3m2t_8.29 tasks. One or two of them are showing no CPU use, though. Not sure how to link PIDs to tasks, though.

But looking more closely at the task, "CPU Time" reports "1d 03:51:19" on an elapsed time of 6d and change.

There's no C:\Program Files\BOINC\data directory, but I've got a C:\ProgramData\BOINC directory with that sort of stuff.

stderr_rm and stderr_um are both empty.

Detaching shared memory segment...

I don't see anything obviously wrong in them... I'm tempted to suspend and resume that task, see if it comes back up properly.

Thanks. I can see the problem.

I have 9 tasks ... I see 9 wah2_8.29 tasks, 9 wah2am3m2_8.29 tasks, and 9 of the wah2am3m2t_8.29 tasks. One or two of them are showing no CPU use, though. Not sure how to link PIDs to tasks, though.

Several ways to link PID&task, I like Resource Monitor. Start it up. On the CPU tab, scroll to find the CPDN task process you are interested in. Click the little checkbox left of the process you are interested in. Once clicked, open up the 'Associated Handles' section (little up/down arrow on the title bar below), and it will show you all the files and folders associated with the process.

The last lines of that output from the global model 'stdout_um.txt' show the problem: 'Closing model'. That means the model has stopped but for some reason boinc hasn't recognised this and the process hasn't exited. That's why the model has hung up. The global model isn't running so the other two processes are just sitting waiting.

Rather than suspend/resume, I would shut down the client to kill the processes. Make sure they really have gone (check Resource Monitor) and then start up the client again. It's possible the tasks will then error but that's what you need anyway.

HTH

p.s. I've just checked the machine this was running on. I noticed it's only got 8Gb RAM. How many CPDN tasks are running simultaneously and how much of that 8Gb is BOINC allowed to use? Am thinking you might have hit a memory limit causing this odd behaviour.

It's running 9 tasks, due to disk limits, showing 6.8GB of 8 in use, and BOINC is allowed 90% of RAM.

I'll just reboot the VM and up the RAM to it - it's able to have at least 12GB, the system isn't running anything else.

The reason I ask this is because up to now it's appeared that only AMD PCs can run the 1008 tasks (though not produce correct results).

Hello,
I have 4 1008 tasks at about 60% on a Ryzen 3600x. Is it worth continuing them if they don't output correct results or should I abort them?
Thanks!

I am going to let mine continue unless I see a message from Glen here or someone else at the project asking for them to be aborted. (Mine are suspended currently to let some testing branch tasks go through.

Please let it run. We're not 100% certain of the results. They are a useful comparison to the failed Intel runs.

Ok, will do! Thanks 👍
