Real-time scheduling sets the niceness, or scheduling priority, of the application to a real-time priority. Basically, it makes your application the most important thing your OS is running. Basically, don't set it to use realtime if you don't know what your program might do as it could lock it up. To allow non-root users to set this, edit /etc/security/limits.conf and add this line: @usrp - rtprio 50 Tom _______________________________________________ Discuss-gnuradio mailing list [email protected] http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
