Hello everybody,

is there, or is there anything planned for a interface to the vboxheadless instances, like ssh or a small web server?
btw i cannot locate the vm's via vboxmanage, the vboxheadless-tool doesn't seem to work either.
tried running as root, still no instances, this does normally also include the vm's for user bonic_project, right?

thx

I love the support level in this forum... non existent...

Nope you cannot see the VB VM of any VB based boinc project (vLHC, CMS-Dev, RNA, Atlas) : they run under the boinc_project user and the VB management tools never see them (under Mac at least).

Thank you.
I am a recent number cruncher for Atlas,
I have an iMac now considered "vintage' mid 2007 model but which with the aid of the RAM being "Ge'd" up to 6 runs El Capitan in constipated mode. Version 10.11.6
Atlas hardly flies, but I'm content.
Prior to installing,I was advised to use an invitation code,download VirtualBox with it's extension and set various preferences.
It transpired that I didn't have to use this Code, things happened rather automatically (it's the way I like it) and from what I can see, the virtualBox that i downloaded plays no part in the proceedings.
From your comment, it would appear that the VBox is superflous..
Any reason not to install it to lighten my load?

regards,

Tom Johnson.

Welcome Tom ,

VirtualBox is strictly necessary to execute boinc tasks which are executed inside a virtual machine.
Why ?
Because the atlas jobs are written for linux and it's the easiest way programmers found to be run over all the platforms (windows,mac,...).

VirtualBox can be downloaded from the boinc site or the oracle site.It's safer.(No need of invitation code)

To lighten the load, you have to create an app_config.xml file to be placed in the atlas directory (Macintosh OS X: /Library/Application Support/BOINC Data/projects/atlasathome.cern.ch/),in your mac computer.It allows you to limit to only one WU running at a time and only one logical cpu used for the atlas tasks.

You can find the documentation and adjust your file to your configuration.

It would look like :


<app_config>
<app>
<name>ATLAS</name>
<max_concurrent>1</max_concurrent>
</app>
<app_version>
<app_name>ATLAS_MCORE</app_name>
<avg_ncpus>1.000000</avg_ncpus>
<plan_class>vbox_64_mt_mcore</plan_class>
<cmdline>--memory_size_mb 3300</cmdline>
</app_version>
<project_max_concurrent>1</project_max_concurrent>
</app_config>


if you want to reduce the load at the minimum.
It's up to you to do the best settings.

Have a nice crunch...

Thank you, Phillipe,

I think i'll let my present setup continue.
I may not understand it, but it works!
A bit intimidated by all the PhDs you have around the place perhaps.
Regards etc.,
Tom
