Just-in-Time Compilation

High-performance computing demands efficiency, and just-in-time (JIT) compilation is a technique that optimizes code, allowing it to execute faster by compiling portions at runtime. This chapter explores how JAX leverages JIT compilation to accelerate numerical computations and machine learning models, ensuring you maximize your hardware capabilities.

Throughout this chapter, you'll discover how JIT compilation can transform your JAX functions into highly optimized machine code, significantly boosting execution speed. We'll cover the basics of applying JAX's @jit decorator to your functions, examine the performance impact, and understand the scenarios where JIT compilation is most advantageous. We will also delve into the trade-offs involved, such as compile time versus execution time, to help you make informed decisions about when and how to use this powerful feature.

By the end of this chapter, you will have a solid understanding of just-in-time compilation within JAX, equipping you with the skills to enhance the performance of your data science projects effectively.
