GNURadio and multi core processors

GNU Radio

Howdy,

How well does GNURadio + GRC play with multicore processors? I’m running
a
program that streams video on an Intel Atom-based processors and it’s
not
really able to keep up. I was going to try out the dual-core Atom’s if
GNURadio would play nicely with it.
Thanks.

GNU Radio by default uses a “thread-per-block” scheduler, which means
(as the name implies) that each block you instantiate runs in its own
thread. This architecture scales very well to multicore processors, so
I expect you’ll see a nice boost in performance with a dual core Atom.

Dave,
I’m trying to get this into as small a package as possible, because it’s
going underwater :slight_smile: At 64lbs of buoyancy per cubic inch, every bit
counts!

Er, that’s cubic “foot” … not inch :slight_smile:
