I built Tom's safe_align branch on E100 and ran volk_profile. It segfaulted on "RUN_VOLK_TESTS:volk_32fc_s32fc_multiply_32fc_a. I'll get a stack trace for you.

We are interested in determining the best architecture at instantation time. What would be the best strategy? We though about running the same operations several times for each architecture, measure the results and use the fastest one for the processing blocks. Would this be the right approach? Carles, Run volk_profile. It does exactly what you said, and writes the results to ~/.volk/volk_config. Volk reads this file when it is involked (sorry) to determine which particular function to execute. So all you do is run volk_profile once on any given machine, and it's optimized. --n Carles, This is discussed on the webpage: http://gnuradio.org/redmine/projects/gnuradio/wiki/volk We'll be updating this as things progress with Volk, but the profiler info is there already.
