BOINC is in control of how many tasks are run at a time. You can control it by limiting RAM available to BOINC. I think you can also set the max_concurrent value in one of the files too.
2) Message boards : Technical News : Due to user feedback and an attempt to reduce the load on our servers, we increased the default target run time from 3 to 6 hours, increased job deadlines to 14 days, and added the target cpu runtime option of 2 days (Message 106397)

You might just need to click "Allow" at the bottom of this page:
https://boinc.bakerlab.org/rosetta/show_host_detail.php?hostid=3371484

It disables the VirtualBox jobs if your computer returns errors, which all of mine do from time to time, usually due to the not starting bug, or the dropping to 0 CPU usage bug.

What I would do is:
1 restart BOINC Manager.
2 If that doesn't work, abort those tasks.

If you do 2, you will probably have to go to that computer's page on the website and re-enable the VirtualBox tasks using the Allow button at the bottom.

I'm nothing to do with the project - I just want to help where I can.
5) Message boards : Number crunching : is that right R@H needs 19GB diskspace for WU (Message 106253)

Post:
I believe the 19GB will include the amount of free space required by your BOINC settings, as well as any additional amount for the tasks.

Update on the AVX requirement as final confirmation, not that I think any were needed: I upgraded a 6th gen (Skylake) Pentium (no AVX) to an i5 (with AVX) and it now completes the VB tasks.

If they were to share the tools used to create the virtualbox, would anyone here be able to convert it to a non-VB task? I.e. do the work for them and send the method back? I expect they are all contracted to do specific work based on funding etc which this would fall outside of.

Does anyone know if we'll be running any of these tasks?

The first ones are out today it seems:

Yeah I've run memtest on all of my machines - so easy from the start menu in Windows these days. No issues detected though.

Agreed. But why do my i5 and 3900XT virtually never have a faulty task?

Yeah, that I don't know! My 3700X seems to have more issues than my other machines. Maybe because I use it more. Or maybe these tasks are more sensitive to something like memory errors.

I don't experience this. I have two computers that do 99% of them ok. I have 5 computers that never do them. Perhaps there's an instruction in CPUs required for a small number, but all my machines are either new enough to have it or old enough to break every one of them.

Only your 3800XT and your i5 have AVX so the other machines will all suffer from the Intel MKL crash.

BOINCTasks shows whether a task is using CPU time or not so you can see what to abort.

Yeah unfortunately there are lots of bad VirtualBox tasks that waste lots of CPU time. I don't know of any way to deal with them other than to abort them unfortunately.

Boinctasks is helpful to show any tasks where the CPU usage had dropped to near 0. I find this happens on some machines more than others but I'm not sure why. Windows seems more problematic than Linux.

Typically, I find that VirtualBox tasks that have run for more than 10hrs are broken and need aborting. Unfortunately, that often also triggers the project to stop you getting more VB tasks until you click the Allow button again.

Continuing my post below, the Virtualbox tasks won't run on:

Intel:
Anything older than Sandy Bridge (2nd Gen Core architecture). So Core2 CPUs and older, or original 1st gen Core CPUs (Nehalem) won't work.
Any Pentiums and Celerons older than 11th gen (Tiger Lake)

AMD:
Bulldozer and newer all support AVX, so Phenom CPUs won't work but Bulldozer, Jaguar, Puma and newer should work.[/list]

Post:
To continue the thread of issues with VritualBox tasks, the messages here identify missing CPU extensions (avx, avx2, f16c, fma) as being the culprit for issue #3 in my original post in this thread.

I think it's almost certainly AVX:

We can rule out F16C becuase that was introduced in Ivy Bridge (3rd gen) Intel CPUs, whereas AVX was introduced in Sandy Bridge (2nd gen). My Sandy Bridge machine ran Virtualbox jobs quite happily, but my Nehalem machine (1st gen) doesn't.

We can rule out FMA and AVX2 as they were both introduced after F16C (both in Haswell - 4th gen).

Intel MKL crashes because one of these extensions is missing in the CPU, but presumably either VirtualBox isn't signalling that to the environment correctly, or the OS/scripts aren't picking it up properly and so try to use those missing extensions.

It might be VirtualBox, but might it also just be that the script is setup to assume AVX (or whichever extension is missing) is available without checking?
