Warning: Mixed prefix install is not supported. You need to install gr-fosphor in the same prefix as your GNU Radio install. If you used build-gnuradio this will be /usr/local and this is what's used in the instructions below. If you use a packaged version of GNU Radio, it's most likely /usr and the best way is then to make a package for gr-fosphor for your distribution.

== Bandwidth figures

94 3 horiz0n
There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU.

To build it:
97 3 horiz0n
98 3 horiz0n
{{{
99 3 horiz0n
cd gr-fosphor/lib/fosphor
100 3 horiz0n
make
101 3 horiz0n
}}}
102 3 horiz0n
103 3 horiz0n
Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format.

Try to leave the window to its default size if possible and watch out for the Msps numbers printed out to the console.
