24 | == Bandwidth figures |
||
25 | |||
26 | There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU. |
||
27 | |||
28 | To build it: |
||
29 | |||
30 | {{{ |
||
31 | cd gr-fosphor/lib/fosphor |
||
32 | make |
||
33 | }}} |
||
34 | |||
35 | Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format. |
||
36 | |||
37 | {{{ |
||
38 | ./main some.cfile |
||
39 | }}} |
||
40 | |||
41 | 14 | horiz0n | Try to leave the window to its default size if possible and watch out for the Msps numbers printed out to the console. |
42 | |||
43 | Submit your numbers & help us to create a GPU survey. We are especially interested in the top end and mobile graphics figures. |
