Thanks Robert. I'll investigate the logs and report my findings...

Hi Shayne, It sounds like VPB is black listing cores due to errors on the tasks that ran on these cores, so it's limiting the build to just the ones that are working. VPB does this to handle outages on a network build where problems on a single machine don't bring the whole build to a halt. If it is black listing that is limiting the cores that are available then you'll need to look at the logs to see if there have been any failures and any reports of blacklisting. You will find a logs directory in the directory that you ran the build from and within this there will be lots of separate .log files that will provide the output from each osgdem run, one per task. If it isn't black listing then you'll need to try running vpbmaster in a debugger and see what is going w.r.t threading. Robert.

I would have thought that up to 16 threads would have been working as the build process went along to completion. There is no indication of any errors in the output so far. > > Has anyone else seen this or know what might be going on? > > Thank you! > -Shayne > > ------------------ > Read this topic online here: > http://forum.openscenegraph.org/viewtopic.php?p=36210#36210 > > > > > > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org > _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
