Threads

The thread keyword spawns concurrent threads of execution.

---

Syntax

thread {
    // runs in a separate thread
    HeavyComputation();
}

---

Thread Semantics

• Each thread block spawns a new OS-level thread
• Execution continues immediately in the calling code
• Use for CPU-bound parallel work across multiple cores

---

When to Use

Scenario	Use
Independent CPU computations	thread
Data-parallel loops	parallel for
GPU tensor operations	gpu { }
I/O-bound operations	async / await
