All tasks are immediately ending with computation error. This is on both windows and linux hosts. The windows host uses tthrottle and the linux is at 50% cpu time. My next step is to disable/100% these. The delay to update the project is so long I'm having a hard time troubleshooting. Any other ideas?

And now I've been put in time out making troubleshooting even harder. One host gets this, another gets no message whatsoever. Just zero tasks.

On your 2600X, you don't have the 32bit libraries loaded that climateprediction.net needs. Sticky at the top of the Linux forum.

https://www.cpdn.org/forum_thread.php?id=8008&postid=59939

Since you're using 19.2, it's based off of Ubuntu 18.04 so use that command in the sticky to get the needed libraries.

Edit...also, you only have 8 GB of RAM on the 2600X with 12 cores that boinc sees. This is problematic in terms of memory usage if running on all cores, and I would suggest limiting the number of CPUs used by boinc to at most 6 for the hadam4 N144 models, or at most 4 if you get the hadam4h N216 models.

Also, the "error messages" in your first post aren't. They're just BOINC saying that it can't find the output files to upload.
Which is obvious if the model crashed before they were created.

The real error message(s) will be before that in the list.

Added the linux packages. I assume I have to wait 24 hours to expect an update.

Any ideas on the windows host? There are no other errors in the logs.

It's possible that the "day" will reset at 00 GMT, so it may ask for work after that.

The Windows errors are odd, with the "cannot find the device/drive specified" problem. I've had these types of errors occasionally, but not in bunches like that. It may have to do with the system trying to do too much disk reading and writing simultaneously, but that's just a hunch. If those types of errors continue frequently, I'm not sure what the solution would be.

Perhaps the errors are something to do with Windows' VirtualBox.

Also, the models are taking 13 hours to clock up 40 minutes of model time.

geophi, "cannot find the device/drive specified" - what are you referring to?

Les, where are you seeing that result? And CPDN uses virtualbox? I don't see a VM created by it. If you're seeing something on the back end, I did attempt attaching a linux VM to replicate the problem fresh but am still not receiving any tasks.

I do see that presently the only work available is for one of the linux applications, so I'm suspending the windows host.

Your Windows computer's tasks are here https://www.cpdn.org/results.php?hostid=1496463

If you click on the individual task number, you'll see a section labeled stderr where some additional errors are written. The problem up near the top of that listing is what resulted in the task error "The system cannot find the drive specified."

About virtualbox: I'm referring to the info about your computer, here under Virtualization

cpdn DOESN'T use virtual box, but you have it installed and enabled.

Ok, thanks. I've suspended all but the 2600x linux host. It's limited to 1 core, 100% cpu time, and run-always. It's 0030 GMT and 30 minutes left until my next update. Cue suspense.

:(
I've always thought that the "midnight" was where that project's server was.
Perhaps it's where the person's computer is.

I run some of my Linux boxes on UTC/GMT time, so that may be why I remember that.

Got a task on the linux host! So that was the libraries - thanks! Only letting it crunch the one task for now to test and I expect to see that run time come down. Plus this rig is going down tomorrow for hardware changes as it's a project-in-progress (literally building a winter space heater).

Still no work available for windows so have to wait to sort that drive error. It's an m.2 nvme and scores >1k on AS SSD so I don't think it's a speed issue. But I've limited it to one core so when a task does come down I can maybe rule that out.
