Re: [Discuss-gnuradio] benchmark_* not working correctly

[Tim Meehan]

does ./benchmark_loopback.py work?
If this works then the generic vs simd is not an issue for you.

If the loopback does not work I would try an svn update and rebuild.  Eric fixed
the issue with the simd code last week.

The original poster (dev) had some issues with the _tx and _rx but I have been unable to
test that because I am without a transmit USRP module at the moment.

There is probably an easier way but to determine if you are using simd and generic take a look at the MD_CPU line in the Makefile in the filter directory.  If this says x86 you are using the simd code

We are running the benchmark_tx and _rx scripts, and they work fine for our test (we changed the transmit side to send lines of text from a regular file) with the default gmsk modulation, but neither of the other two accepted modulations (dbpsk and dqpsk) are received correctly.  We are using 2 FLEX1200's attached by USB to two separate laptops and we are transmitting at 1.2GHz.  We are thinking that the receive side needs time to sync up but in sending a line of text at a time, we're not sure how best to sync up (or if that is the problem).  The receive side displays the payload as a mixture of chars from the different lines in the file -- doesn't make sense.

In reading this thread from the mailing list, I wasn't sure if the _simd issue is affecting us.  If that's not the default build option, then I doubt it's affecting us (but how do we tell if we are _simd or _generic?).  Any help with this stuff is appreciated.
