| 66 | == Bandwidth figures |
||
| 67 | |||
| 68 | There's a benchmark program available which allows to estimate the maximal bandwidth that can be processed with a specific GPU. |
||
| 69 | |||
| 70 | To build it: |
||
| 71 | |||
| 72 | {{{ |
||
| 73 | cd gr-fosphor/lib/fosphor |
||
| 74 | make |
||
| 75 | }}} |
||
| 76 | |||
| 77 | Then execute it by providing a prerecorded complex float file (a couple of 100MB should be fine) in gnuradio format. |
||
| 78 | |||
| 79 | {{{ |
||
| 80 | ./main some.cfile |
||
| 81 | }}} |
||
| 82 | |||
| 83 | 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. |
| 84 | |||
| 85 | Submit your numbers & help us to create a GPU survey. We are especially interested in the top end and mobile graphics figures. |
