Can you look at the logs in boincmgr with the (misleading) "Show graphics" buton?

Here is an excerpt from the boot log:

Also the efforts to build and maintain this is only worth it if it makes a difference to the experiment and as over the next 5-10 years the projections on computing supply and demand differ by a factor of 10, this project may turn out to be quite helpful.

I think the potential and value of BOINC has been proven by Atlas@home, where BOINC has consistently been one of the largest if not the largest production contributor to Atlas simulations. http://atlasathome.cern.ch/atlas_job.php
Also, and as a result I believe, the level of support for BOINC by Atlas has been excellent.

So I would expect BOINC to be eventually as important to CMS.

Just curious to see your timing goal to start production work? These latest 250 unit jobs seem to be going well for me.

Thanks!

Doesn't seem to use much CPU (13%). Is that a sign of a problem?

Is that on your host machine or in the ALT+F3 VM console?
Of course, if it's an 8-core machine, Task Manager will show 12 or 13% for a full core's usage...

That was in BoincTasks v. 1.67, but for the ALT+3, mostly zero, up to one moment 20.5%. Seems like no work is being done.

I have no doubt that this will be a successful test for CMS since ATLAS tested BOINC results for months before accepting BOINC as part of their regular production team.

Ok seems that the problem with the console is Windows 10 related because I cant connect to the consoles from vLHCathome, too.

I have the same issue with my 2 Windows 10 boxes. Hopefully that is one of the things Oracle is fixing so that Virtual box is Windows 10 compatible.

Hi, I am a fresh and new user ;-)

Downloaded the first WU and has already started to crunch.

I looked inside the VM (as learned by vLHC) and it is saying something like: Begin processing the 6th record. Run 1, Event 906, ...

So, I think all is running as it should ?

Cheers, Yeti


Well I know you have plenty of cores especially right now with no Atlas tasks.


Am I correct that this CMS is just doing test work and not "real" project work? I would add more cores if I knew we were working on the latter.

Thanks!
