Hi Robert, I spent few hours on this and I have things to report. First, there are code mods I did to fix it actually, but, there is a comment like "// Must protect linux from realtime.", PThread.cpp around ln: 323. I have mods to submit but can not do that yet since there are issue with the config. Seam like these are not getting defined on my 64bit Ubuntu (I am not a config guru so I need help from others on this): __linux, __linux__, HAVE_THREE_PARAM_SCHED_SETAFFINITY, HAVE_TWO_PARAM_SCHED_SETAFFINITY ... etc. and all of these that should be set from the pthreads/CMakeLists.txt but are not. Also ALLOW_PRIORITY_SCHEDULING is not set at all. I had to hard code these defines to make it work but someone need to look in the configuration of pthread or at least give some hints so I can dig into
