Yeti, thanks! Resetting lhc@home project seemed to do the trick, alt+f3 showed no much activity in first 10 mins but then 3 cores started crunching hard at 100%. :) Hopefully it will stay that way when I resume other projects as well, for now I will try to run a few ATLAS WUs in a row.
A lot of stuff going on in alt+F2 too.

It seems I can't edit my own previous post?
Anyway I cancelled my previous task and started a new one. Now alt+f2 and alt+f3 works in the VM console and it seems that the cores are being used for only around 0.3%. This new task has been going at it for 14 hours now and CPU time is only 33 minutes. Looks like it happens to every ATLAS WU I get.
I will try to look around the forum for a solution, if there is one..

EDIT: I already added app_config.xml for the task, currently I tell it to use 3 cores and ram limit is set to 8 gb. Any other suggestions for the xml?
app_config.xml:
<?xml version="1.0"?>
<app_config>
<project_max_concurrent>3</project_max_concurrent>
<app>
<name>ATLAS</name>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>ATLAS</app_name>
<avg_ncpus>3.000000</avg_ncpus>
<plan_class>vbox64_mt_mcore_atlas</plan_class>
<cmdline>--memory_size_mb 8000</cmdline>
</app_version>
</app_config>

So I'm trying to figure out why my LHC tasks in linux seem to run so slow.
Atlas simulation 1.01 (vbox64_mt_mcore_atlas) has been running for almost 13 hours now and is currently at 99.994%. However it is progressing very slowly at this point.
alt+f2 does nothing in the vm console, only alt+f1 and alt+f6 switch to some other information. I'm using Ubuntu, I have 16gb RAM and i5-6500 as cpu. My cpu usage is currently set at 99%, however 3 cores are used by LHC and 1 core is used by 3 Einstein WUs at the same time. Also LHC priority is half of normal.
Task manager shows 5gb of 15.6gb used and 1 core is running at 100% while other three are usually slacking around 10-25%.

As the title says, over half of my tasks get an error "Error while computing", when I open a specific task then it says "errors: too many total results". What causes it and how to fix it?
This is how it looks like: https://imgur.com/a/6XgcI


UPDATE: Never mind, looks like I missed a stickied thread in this sub-forum about Windows 10 users needing to update their Oracle VM, I will update it and see if it fixes the situation.
