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

the issue with the simd code last week.

Just reconfigured and tested, looks like benchmark_loopback is working
fine now on all my systems. Thanks everyone!

The update seems to work. I re-ran configure and verified that the SSE code
was being used. make check passes and the original code Dev had a problem
with "benchmark_loopback.py" works correctly.

Tim,
I've checked a trial fix into the trunk as of r6575.
Can you please update and let me know if it fixes your problem?
Thanks,
Eric

Eric,
The QA code (qa_gr_fir_ccf.cc) forces a 16 byte alignment. When the
malloc16Allign is replaced with a regular malloc in the QA code, make check
fails.
I believe that there is an additional requirement that the data passed to
the low-level SSE code have the real sample start on the 0th or

Make check does pass, and there appears to be QA code (qa_gr_fir_ccf.cc). I
am not sure that
if the QA code actually gets called by a top level "make check" If you
would like me to look
into it I can but I suspect whoever wrote the QA code originally could do it
a lot faster than me:-)
On 10/1
Just tried this on my laptop which seems to be using whatever
non-functioning code Tim mentioned. Make check passed successfully.

Tim,
I reconfigured both my 32 bit laptop and desktop to use the generic,
and they both work now with benchmark_loopback. Unforunately, I still am
unable to communicate between any USRPs with the benchmark_tx and _rx
scripts. Thanks for all your work on this. When I have some free time
I'll
Dev, Johnathan and All,
After re-reading Dev's emails about 64 vs 32 bit and realizing that
gr_mpsk_receiver_cc.cc has not changed in some time, I took another look at
this.
On my build gr_fir_ccf->filter() was not functioning properly. This is
called be the gri_mmse_fir_interpolator from gr_mps
Dev, Johnathan, and all
After spending some time looking through gr_mpsk_receiver_cc.cc I am not
sure how this
ever worked. Below is a patch that works for me. There are two minor
changes
1) I did not understand how the delay line for the interpolator could work
as coded so I changed it to wha
Running benchmark_loopback.py with gmsk (-m gmsk) seems to work
correctly for all my systems. Unfortunately, the same doesn't seem to be
true of the benchmark_rx and benchmark_tx, which use gmsk by default.
Changing them to any of the other modulation options didn't yield any
results either.
I have some additional hints.
When I run with 2 samples per symbol (the default)
./benchmark_loopback.py -s 20 -M 0.004 -S 2
ok = False pktno = 19 n_rcvd =1 n_right =0
ok = False pktno =7 n_rcvd =2 n_right =0
ok = False pktno = 180 n_rcvd =3 n_right =0
I've been looking into this problem further. I apologize in advance for
the long post. To make things easier, I'll represent the three computers
I'm using as follows:
32deb - 32bit Debian desktop
32red - 32bit Fedora laptop
64red - 64bit Fedora desktop

I suspect that the "pktno" from below is just garbage from false syncs.
I placed some prints in pkt.py
send_pkt places a message on the queue 667 times.

Were either of you able to resolve this? Any hints on where I might try to
find the problem? I spent some time digging around pkt.py.
I get similar results running svn 6504 under Debian testing (Lenny). This
was a fresh install on a clean machine. I do not see the same problems on a
