Compute theoretical upper computation efficiency bound corresponding to some actual execution.
| void starpu_bound_start | ( | int | deps, |
| int | prio | ||
| ) |
Start recording tasks (resets stats). deps tells whether dependencies should be recorded too (this is quite expensive)
See TheoreticalLowerBoundOnExecutionTime for more details.
| void starpu_bound_stop | ( | void | ) |
Stop recording tasks
See TheoreticalLowerBoundOnExecutionTime for more details.
| void starpu_bound_print_dot | ( | FILE * | output | ) |
Emit the DAG that was recorded on output.
See TheoreticalLowerBoundOnExecutionTime for more details.
| void starpu_bound_compute | ( | double * | res, |
| double * | integer_res, | ||
| int | integer | ||
| ) |
Get theoretical upper bound (in ms) (needs glpk support detected by configure script). It returns 0 if some performance models are not calibrated. integer permits to choose between integer solving (which takes a long time but is correct), and relaxed solving (which provides an approximate solution).
See TheoreticalLowerBoundOnExecutionTime for more details.
| void starpu_bound_print_lp | ( | FILE * | output | ) |
Emit the Linear Programming system on output for the recorded tasks, in the lp format
See TheoreticalLowerBoundOnExecutionTime for more details.
| void starpu_bound_print_mps | ( | FILE * | output | ) |
Emit the Linear Programming system on output for the recorded tasks, in the mps format
See TheoreticalLowerBoundOnExecutionTime for more details.
| void starpu_bound_print | ( | FILE * | output, |
| int | integer | ||
| ) |
Emit on output the statistics of actual execution vs theoretical upper bound. integer permits to choose between integer solving (which takes a long time but is correct), and relaxed solving (which provides an approximate solution).
See TheoreticalLowerBoundOnExecutionTime for more details.
