Hi Robert, actually this piece of code from pthreads.cpp was the only one that was containing the word "affinity". :-) so that was just a guess that this could be the problem.
Nevertheless i was not able to understand why the whole application did not receive the process affinity mask with only one CPU activated after i recompiled osg with BUILD_USE_QTTHREADS enabled in CMAKE. May conclusion was: The way i built openthreads before caused the affinity mask for the overall process beeing set like this. That means: After i rebuilt osg with qtthreads every just work like expected. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=57637#57637 _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
