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

| ## Manual pinning of thread(s) to CPU core(s) |
| |
| ## Set logical CPU core where main thread runs |
| # main-core 1 |
| |
| ## Set logical CPU core(s) where worker threads are running |
| # corelist-workers 2-3,18-19 |
| |
| ## Automatic pinning of thread(s) to CPU core(s) |
| |
| ## Sets number of CPU core(s) to be skipped (1 ... N-1) |
| ## Skipped CPU core(s) are not used for pinning main thread and working thread(s). |
| ## The main thread is automatically pinned to the first available CPU core and worker(s) |
| ## are pinned to next free CPU core(s) after core assigned to main thread |
| # skip-cores 4 |
| |
| ## Specify a number of workers to be created |
| ## Workers are pinned to N consecutive CPU cores while skipping "skip-cores" CPU core(s) |
| ## and main thread's CPU core |
| # workers 2 |
| |
| ## Set scheduling policy and priority of main and worker threads |
| |
| ## Scheduling policy options are: other (SCHED_OTHER), batch (SCHED_BATCH) |
| ## idle (SCHED_IDLE), fifo (SCHED_FIFO), rr (SCHED_RR) |
| # scheduler-policy fifo |
| |
| ## Scheduling priority is used only for "real-time policies (fifo and rr), |
| ## and has to be in the range of priorities supported for a particular policy |
