That is excellent news, and a good use of BOINC. But when you are ready, you should post a notice in the Projects section of the BOINC forum.

Pity. I joined in 2008, and while I'm a long way from the top of the leader board, I did believe in what they were trying to accomplish.

They may have already accomplished it. We don't know what state they are in. But they were using artificial intelligence to refine the accuracy of their models, and we were doing the training for it. Maybe it is trained enough and they have lost interest.

Was that computer a new host or were you just reattaching a previously attached one?

Host 430922 is showing
Created 27 Oct 2020, 16:29:31 UTC

Yes, I think it was previously attached. I just reattached it today.

Most of mine have been previously attached, but it looks like this one has not.
It just attached it now with no problems:

EDIT: I use BOINCTasks on a Win7 machine to manage my Linux machines on the LAN. That should not make a difference on attaching, but it might.
4) Forums : Technical Support : BOINC 7.16.14 does not work with VirtualBox (Message 22727)
Posted 22 Dec 2020 by Jim1348
Post:
Thanks to the expert help of Gunde on the LHC forums, I was able to solve a problem with VirtualBox (any version). It does not work with BOINC 7.16.14, which I obtained from PPA costamagnagianfranco and was running on an Ubuntu 20.04.1 machine.

Basically, if you have that PPA version, you go to Ubuntu "software and update" and uncheck the line for that PPA then:
sudo apt remove boinc-client boinc-manager
sudo apt install boinc-client boinc-manager

That will install BOINC from the apt repository.
In the case of Ubuntu 20.04.1, it will be BOINC 7.16.6.
In the case of Ubuntu 18.04.5, it will be BOINC 7.9.3.
Either works with VirtualBox.

Since apparently the results aren't being used for anything, "rm -rf /*" should work just fine.

That is what I am wondering about too. They keep the project going, which involves some time and expense by someone.

I hope they are not just storing the disks in a file cabinet somewhere, waiting for someone to use them.

Versions 5.2 and 6.0 are unsupported as of July 2020 per the virtualbox.org website.

But this project is totally unsupported. We are on our own.

Use 5.2.x.

You are welcome. It depends on the OS too. I think it is more of a problem with Windows than Linux.
(I had the problem on my Win7 64-bit machine, but not the Ubuntu ones.)

An earlier version of VirtualBox (5.x) might fix it. There are often problems with 6.x.

What a shame...I'm a U of I graduate...this should be better.

It has very little to do with the U of I. The science professor who did it (Ben Wandelt) was a visiting professor at U. of I., but is now back in Paris. And the software guru who did the boinc2docker code (Marius Millea) is now in California the last time I heard.

I think the U. of I. just runs the server, and replaces a full disk occasionally if someone tells them to. The project is still there, but how much it is being used is not at all clear to me.

I would just wait. The server will probably be fixed in a few days, though it could be next week.
But you can just abort them if you want to. They are easy to replace.

Maybe nothing. But is their MAC application compatible with your MAC version?

It is a little curious. They manage to update the citations to PICO in the science section of the FAQs.
https://www.cosmologyathome.org/faq.php#science
But it appears that is just an automated update service. It shows that it has been used at some time in the past.

My concern is that we have done all that needs to be done, and no more is necessary, or that improved techniques have been developed and PICO is of historical interest only. The fact that they never show up reinforces that belief. But it is still here, if anyone wants to do it.

There hasn't been an administrator around here for years to as much as say "boo".
Sometimes they fix the server outages though, after a while.

I just have been getting the postponed VMs every so often so my machine quits crunching for a bit until I restart Boinc Manager or let it go for over 24 hours. Our applications haven't changed for years. No idea why it changed.

I got that too with VirtualBox 6.1.8, so I went back to 5.2.42.
It seems to have fixed it. I think it is a common problem with the 6.x.x series.

You have almost all errors with:
VBoxManage.exe: error: VT-x is disabled in the BIOS for all CPU modes (VERR_VMX_MSR_ALL_VMX_DISABLED)


You need to enable virtualization (VT-x) in the BIOS.

Even if camb_legacy isn't a priority, I thought you might want to know it doesn't work on recent Linux kernels at the moment.

Good idea, but there is no one here. The server is running, but that is about all.

I started to get this error right after I upgraded to VirtualBox 6.1.0. Someone mentioned that it means that VBox can not respond to the requests from the work units in a timely manner, so they error out.

The solution is to go back to VirtualBox 5.2.34 or earlier.
