== 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
}}}
Try to leave the window to its default size if possible and watch out for the Msps numbers printed out to the console & submit them to us.
