Thread models are conceptual models that represent the flow of execution of concurrent threads within a computer system. Some examples of attributes that may be included in thread models are:
| Threads | The individual units of execution within the system. |
| Concurrency | The ability of the system to execute multiple threads concurrently. |
| Scheduling | The process by which the system determines which threads to execute and when. |
| Synchronization | The mechanisms in place to coordinate the actions of multiple threads and prevent race conditions. |
| Deadlock | A situation in which two or more threads are blocked and unable to make progress because they are waiting for each other. |
| Priority | The relative importance or priority of different threads. |
| Preemption | The ability of the system to interrupt the execution of a thread and switch to another thread. |
| Resource contention | The competition for shared resources by multiple threads. |
| Thread pools | Groups of threads that are managed and reused to improve efficiency. |
Thread models are an important consideration for software developers and system designers, as they help to understand and optimize the concurrent execution of threads within a system. They can be used to analyze and improve the performance and scalability of a system, and to identify and prevent potential issues such as deadlock or resource contention.
