== Bandwidth figures

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

To build it:

{{{
cd gr-fosphor/lib/fosphor
make
}}}

Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format.

{{{
./main some.cfile
}}}

Watch out for the Msps numbers printed out to the console & submit them to us.
