Spawn task function as separate Linux thread
Use this block to create a task function that spawns as a separate Linux® thread. The task function runs the code of the downstream Function-call subsystem block.
Task Name— Name of thread on Linux
Task0(default) | character vector
Assign a name to this task. You can enter up to 32 letters and numbers. Do
not use standard
C reserved characters, such as the
Thread scheduling policy— Thread scheduling policy used by Linux
Select the scheduling policy that applies to this thread. You can choose from the following options:
SCHED_FIFO enables a First In, First
Out scheduling algorithm that executes real-time processes without
time slicing. With FIFO scheduling, a higher-priority process
preempts a lower-priority process. The lower-priority process
remains at the top of the list for its priority and resumes
execution when the scheduler blocks all higher-priority
For example, in the following image, task2 preempts task1. Then task3 preempts task2. When task3 completes, task2 resumes. When task2 completes, task1 resumes.
SCHED_FIFO, displays the
Thread priority parameter, which you can
set to a value from 1 to 99.
SCHED_OTHER enables the default
Linux time-sharing scheduling algorithm. You can use this
scheduling for all processes except those requiring special static
priority real-time mechanisms. With this algorithm, the scheduler
chooses processes based on their dynamic priority within the static
priority 0 list. Each time the process is ready to run and the
scheduler denies it, the operating system increases the dynamic
priority of that process. Such prioritization helps the scheduler
serve the SCHED_OTHER processes.
SCHED_OTHER, hides the
Thread priority parameter, and sets the
thread priority to 0.
Thread priority (1 to 99)— Linux thread priority
When you set Thread scheduling policy to
SCHED_FIFO, you can set the priority of the
thread from 1 to 99 (low-to-high). Higher-priority tasks can preempt
