| 19 | ## The main thread and worker thread(s) can be pinned to CPU core(s) manually or automatically |

| 23 | ## Set logical CPU core where main thread runs |

| 30 | |
| 31 | ## Sets number of CPU core(s) to be skipped (1 ... N-1) |
| 32 | ## Skipped CPU core(s) are not used for pinning main thread and working thread(s). |
| 33 | ## The main thread is automatically pinned to the first available CPU core and worker(s) |
| 34 | ## are pinned to next free CPU core(s) after core assigned to main thread |
| 35 | # skip-cores 4 |
| 36 | |
| 37 | ## Specify a number of workers to be created |
| 38 | ## Workers are pinned to N consecutive CPU cores while skipping "skip-cores" CPU core(s) |
| 39 | ## and main thread's CPU core |
| 40 | # workers 2 |
| 41 | |
| 42 | ## Set scheduling policy and priority of main and worker threads |
| 43 | |
| 44 | ## Scheduling policy options are: other (SCHED_OTHER), batch (SCHED_BATCH) |
| 45 | ## idle (SCHED_IDLE), fifo (SCHED_FIFO), rr (SCHED_RR) |
| 46 | # scheduler-policy fifo |
| 47 | |
| 48 | ## Scheduling priority is used only for "real-time policies (fifo and rr), |
| 49 | ## and has to be in the range of priorities supported for a particular policy |
