Hello everyone.

I hope this hasn't been covered or I have overlooked it.  Does anyone
know of any python scripts in the gnu radio package or any other
effective way of synchronizing the clocks of two USRPs.  I want to see
if I can synchronize multiple modulated packets.

Also, does anyone know how the real-time scheduling feature is
implemented or works.

Thanks for the help

Depending on what's available on your system, it uses either
pthread_setschedparam or sched_setscheduler.  See their man pages for
details on what they do.  Our code is in gruel/src/lib/realtime.cc
