 == 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.
