If/when stats get exported, I was wondering which name is exported. Or if that would be an option to do so or a choice of which one.

It seems like BOINC@TACC might run a bit like the BURP project, which relies on user submissions to send out to volunteer crunchers.

I see there is another batch of work. 6GB of memory usage per task is quite a lot though. Not even 2 minutes on 2 CPU threads with less than 1 used.
3) Message boards : Number crunching : Vbox Requirements (Message 12)

Post:
Some other BOINC projects don't work well with certain vbox versions or not at all. At 1st glance with the other user submitting successful work, that seemed like the more likely culprit. Thus the thread title. So I tried another system of mine and the trend of an older vs newer vbox version didn't fit. So I tried the core count.

If an mt/vbox app doesn't have a thread count limiter setup from the project then the BOINC client will use the max of the system unless limited via an app_config.xml file. If there is a thread count min limit (I think the only project I've seen is Yafu) then users would receive the task afaik.

I checked another user that has some credit with all successful tasks as my tasks were still aborting. They complete some tasks with v5.2.8. I was using v5.2.10 on my 2700x/Ubuntu 18.04 system. So I tried another PC with v5.2.26 on 3570k/Ubuntu 14.04 and it is completing tasks.

Good PC:
https://boinc.tacc.utexas.edu/results.php?hostid=54

So the middle vbox version isn't working. Or is it the host OS? The # of cores?

Edit: I made an app_config.xml to limit the task to 4 threads. No other changes and success. Please limit the tasks to a smaller # of CPUs besides the max. 16 seems too much for your app.
<app_config>
    <app>
        <name>boinc2docker</name>
	 <max_concurrent>2</max_concurrent>
    </app>
    <app_version>
        <app_name>boinc2docker</app_name>
        <plan_class>vbox64_mt</plan_class>
        <avg_ncpus>4</avg_ncpus>
    </app_version>
</app_config>


Edit2: Checking the top hosts. There is only one with more than 4 cores but there is zero CPU time. Other successful hosts are using 2 or 4 cores.
https://boinc.tacc.utexas.edu/results.php?hostid=8

Barely 2 threads of CPU time is being used along with 3135MB of memory.

You're welcome.

I'm sure there's quite a few crunchers out there that are willing to contribute once there is available work.

Not sure which part is the real issue. Some others I see have different messages.
