RTOS 中多核处理器上的组调度
据我了解，Gang调度是一种并行系统的调度算法，它调度相关的线程或进程在不同的处理器上同时运行。 使用成组调度，以便如果两个或多个线程或进程相互通信，它们将同时准备好进行通信。然而，组调度算法如何确定特定的进程集将在它们之间进行通信，从而调度相关的线程或进程在不同的处理器上同时运行？
I understand that Gang scheduling is a scheduling algorithm for parallel systems that schedules related threads or processes to run simultaneously on different processors.
Gang scheduling is used so that if two or more threads or processes communicate with each other, they will all be ready to communicate at the same time. However, how does a gang scheduling algorithm determine that the particular set of processes will be communicating among themselves and hence schedule related threads or processes to run simultaneously on different processors?

组调度通常应用于作业，要么是操作系统默认的，要么是因为作业已被标记为组调度。作业中的所有任务都安排在一起，而不会尝试衡量它们是否都在主动通信。
以下论文有介绍和一些引文，可以帮助您了解帮派调度的背景：

Gang scheduling is usually applied to a job, either by operating system default or because the job has been marked for gang scheduling. All tasks in the job are scheduled together without attempting to measure whether they all actively communicate.
The following paper has an introduction and some citations that may help you get background on gang scheduling:
