Message 7712 - Posted: 2 Aug 2022, 10:29:25 UTC - in response to Message 7676.  

Not intention on my part, but a new kind of task with updated ATLAS simulation software was added recently to the set of tasks automatically submitted here. I've asked the experts to look into why these tasks fail.


The problem is the new software requires a library version not installed in the old VM we use here, so I have blocked these tasks from being submitted.

100 Atlas-Tasks per day and PC.
This never ending tasks are only a handful per day.
You can see this in production for this two PC's.

ALT+F1 or ALT+F2 or ALT+F3 in Virtualbox is not avalaible.
Even when there are only a few, it's worth to find the cause, because they are running endless occupying a slot.
F-key's not available in BOINC's Console is a sign that the VM did not started through.
In Oracle VM VirtualBox Manager you may click the VM when you have that issue and touch the button with the green right arrow "Show" (Zeigen) from the top menu.
Maybe you only get a black screen and have to wake up the display with e.g. only the Alt-key.
You probably also good improve your throughput by reducing the number of cores to 8 per VM and increase the number of tasks to 7 or even 8.

There is no problem, because of Number of Tasks, or number of using CPU's.
Had at the beginning (2.5 Months ago) this all checked.
for example from Threads (128) to use only Cores(64).
There are three free CPU's, when running no -dev (three, because Einstein@Home use one CPU).
