1) Questions and Answers : Windows : Message: Postponed: VM job unmanageable, restarting later (Message 488)

There isn't. Here is a screenshot of my event log. I see that it found it, and something's missing. Should I have the config file in the nanohub file, or a folder up?


The log file said it found the file. Its in the right spot.

This is the content of mine and it works.

<app_config>
   <project_max_concurrent>10</project_max_concurrent>
   <report_results_immediately/>
</app_config>

So, I have a .xml file with just,

<app_config>
<project_max_concurrent>3</project_max_concurrent>
</app_config>

in it, and I'm still having the same issue, despite restarts and using the read config option in BOINC. I'm confident that the .xml file is actually an .xml file, since I went to codebeautify.org to enter in the above code, add in the necessary syntax, and download it as an XML file. It is in C:\ProgramData\BOINC\projects\boinc.nanohub.org_nanoHUB_at_home, and I'm pretty sure that's the right location. Can anyone suggest what I'm doing wrong?


Did you re-read the config files to tell BOINC to look at the file?
After doing that check the Event log. There will be an error or a line saying BOINC found the app_config.xml file

The tasks only run for several minutes on a CPU, in a VM. A GPU version is not the solution to every compute problem. You're a person with only a hammer as a tool and only see nails. Stop with the GPU suggestions.

I just abort tasks that run for more than ~15min. Some run and complete with longer run times than that but most time out.

Would it be possible to know something about the project we are currently working on? That would be very interesting and also provide an incentive to keep working on the project.
Thanks!

My PCs have several versions of vbox. Only one has validate errors but not every single task. At 2gb per task that's only enough to run maybe 1 depending on other uses.

I'm seeing more and more of these along with ones that run for so long and abort. Task conditions have changed the past couple of days.

Try to stick to VBox version supplied with Boinc installation file and limit amount of tasks running consecutively.
nanoHUB is real memory hogger.


Running out of memory would cause errors, not invalids.

Hello,

about 90% of my tasks are with "Validate error" mark and only few are validated as correct.

Where is the problem?

https://boinc.nanohub.org/nanoHUB_at_home/results.php?userid=50955


1 - That is a private link only you can see.
2 - You're nowhere close to 90%. 754/1286 is 58%. Still pretty bad.
3 - 3 of my 4 hosts have zero invalids. The 4th has 18% invalid rate.

All of mine are on Linux. 2x AMD Zen PCs, a 3570k and the 2P 2670v1 with Invalids. The 2P is the only one on Mint 17 while the others are on Ubuntu 18. It also has the most memory at 128GB so it won't ever run out.

You're on Win10 and gemini is on some Linux version. I don't really see a connection between OS/hardware. Your VBox version is 5.2.8, gemini8's is 5.1.12r112440 and my good ones are 5.2.26 or 6.0. The bad one is 5.0.2.

I've begun aborting anything that is not _0. I won't help if I'm the initial user but most _1's I've had timeout. An admin and fix the issue if the don't want this type of behavior.

The only thing we can do (have done, will do) is increase the time limit for all WUs produced by the nanoHUB tools that have a lot of failures with the same error. For example, yesterday two tools produced most of the time limit errors (1% of all WUs), so we increased the time limit for all WUs produced by those tools.


Why not just set it to the same as the deadline and be done with it? Why is there an artificial limit that wastes resources?

This says aborted by client but I sure did not abort it.

Like 7 of those and 163 of the 'Validate error'. 170 out of 170 with errors.

The batch I just got only ran for a couple of minutes. Guess this project isn't for you.


I think you are confusing run time and deadline here. An eight-hour deadline is ridiculously short, especially when you run more than one project -I run forty.


I am not.

If someone can't complete a task that will run for like 5 minutes and that starts immediate in high priority then again, the project is not for them. The deadline is short but if they don't run their PC all the time then they can't expect to have every project cater to them.

No matter if you run 1 thousand projects, the tasks are high priority and will run right away.
