| 89 | == Bandwidth figures |
||
| 90 | |||
| 91 | There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU. |
||
| 92 | |||
| 93 | To build it: |
||
| 94 | |||
| 95 | {{{ |
||
| 96 | cd gr-fosphor/lib/fosphor |
||
| 97 | make |
||
| 98 | }}} |
||
| 99 | |||
| 100 | Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format. |
||
| 101 | |||
| 102 | {{{ |
||
| 103 | ./main some.cfile |
||
| 104 | }}} |
||
| 105 | |||
| 106 | 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. |
| 107 | |||
| 108 | Submit your numbers & help us to create a GPU survey. We are especially interested in the top end and mobile graphics figures. |
