From now on, GNSS-SDR (and any other program of your own that makes use of VOLK_GNSSSDR) will benefit from the acceleration provided by SIMD instructions available in your processor.
|
||||
|
||||
The execution of ```volk_gnsssdr_profile``` can be set automatically after building, leaving your system ready to use:
|
||||
|
||||
~~~~~~
|
||||
$ cmake -DENABLE_PROFILING=ON ../
|
||||
$ make
|
||||
$ sudo make install
