The maximum number of job threads that the job system can create.

Definition

public const int MaxJobThreadCount = 128

Remarks

This maximum is the maximum number of threads that the job can system support. However, the maximum number of job worker threads that the job system creates is lower because the job system doesn't create more job worker threads than logical CPU cores on the target hardware. This value is useful for compile time constants, however when used for creating buffers it might be larger than what you need. If you want to allocate a buffer that can be subdivided evenly between job worker threads, use the runtime constant that JobsUtility.ThreadIndexCount returns.

Examples

using UnityEngine;public class JobWorkerExample : MonoBehaviour{    void Update()    {        // Sets worker count thread to 1        Unity.Jobs.LowLevel.Unsafe.JobsUtility.JobWorkerCount = 1;        // Sets worker count thread to 4        Unity.Jobs.LowLevel.Unsafe.JobsUtility.JobWorkerCount = 4;        // Reads the value of JobWorkerCount and outputs it to the Unity log        Debug.Log("${ Unity.Jobs.LowLevel.Unsafe.JobsUtility.JobWorkerCount}");    }}
