You are at the right place, but you can only change the values for VMs while they are not running.

Still no update in stats.
Is no-one there, do you not know how to do it, or do you just not care ?


It should be a cron job, running several times a day. Not a just-run-once-in-a-while-when-we-feel-up-to-it.

It would help if there was more communication from the project about what is going on or my fellow crunchers will continue to loose interest in the project.

Can't say I did anything different other than install BOINC from the Desktop into the Home Folder ... weird


But why do you -and others- install BOINC in the home folder? What is the advantage?

So the export stats files date from the 13th of December, 2019.....which was indeed on a friday.


The situation is still unchanged: all export stats files are from December the 13th, 2019....

Each WU same status
what can i do ?


What version of Virtualbox do you use? 5.2.8 is known to work. I had some luck sometimes using 6.1.10, before they all errored out with "Access Violation (0xc0000005) at address 0x00007FFE861C0907 read attempt to address 0xFFFFFFFF"

I am now using 6.1.12, which gives the same error.

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?


It -the BOINC app_config- isn't meant to be proper xml. It is meant to be a *txt file, saved as *xml only.

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.

Your cleanup fails because it wants to remove a Windows virtual machine, while the actual virtual machine is a Linux one.
Because the cleanup fails, RAM is nor freed. So, after a few Virtual machines have run all available RAM is in use and the system gets out of control.

My last three tasks were reported as having ended in error on your site while the VMs were still running on my machine


The last bunch does the same, but now the system almost gets out of control while the VM runs and the WU is still on the system too.
System freezes, other projects get errors.

Your VMs have far too little video RAM too -it is being marked as an invalid setting.
