Hi,
What options are there for profiling GNU Radio code? I've done some
Python profiling, and some C profiling, but what options are there for
this crazy SWIG-driven mix of the two?
Also, a flow graph question. In the main loop of the transmit path of my
benchmarking program, I have the following (hopefully self-explanatory
code):
fg.start()
self.num_to_send = options.packets
self.bytes_per_packet = options.bytes
util.rand_init(options.seed)
for i in range(self.num_to_send):
# generate random payload here into buf
buf = util.random_bytes(self.bytes_per_packet)
if i % 10 == 0:
print "> sending packet #", i
mac.send_buffer_unreliably(buf)
# sleep(.01)
# sleep (1)
# sys.exit(0)
fg.stop() # tell flow graph to stop.
fg.wait() # wait for it to finish
If the sleep(.01) line is uncommented, then the flow graph does not
stop, and instead I quit using the sleep(1); sys.exit(0); however
everything works fine with no sleeping. What could be causing this? Is
it something weird involving code running in the same thread that
shouldn't be?
Thanks,
Dan
