| 157 | the necessary interface to the benchmark machinery.\r |
| 158 | \r |
| 159 | The tests must set .rounds to a value high enough to let the\r |
| 160 | test run between 20-50 seconds. This is needed because\r |
| 161 | clock()-timing only gives rather inaccurate values (on Linux,\r |
| 162 | for example, it is accurate to a few hundreths of a\r |
| 163 | second). If you don't want to wait that long, use a warp\r |
| 164 | factor larger than 1.\r |
| 165 | \r |
| 166 | It is also important to set the .operations variable to a\r |
| 167 | value representing the number of "virtual operations" done per\r |
| 168 | call of .run().\r |
| 169 | \r |
| 170 | If you change a test in some way, don't forget to increase\r |
