Designing Concurrent WASM Applications
Learn best practices and patterns for structuring your WASM applications to leverage multithreading effectively.
Intro to Concurrent Design
Welcome to designing concurrent WASM applications! In previous lessons, we learned about Web Workers and SharedArrayBuffer.
Now, let's focus on structuring your WebAssembly projects to effectively use multiple threads. This means planning how tasks, data, and communication flow between your JavaScript and WASM modules.
Identifying Parallel Opportunities
The first step in concurrent design is to identify parts of your application that can run in parallel. Look for tasks that are:
- CPU-bound: Heavy computations that take a long time.
- Independent: Can run without waiting for other tasks.
- Divisible: Can be broken into smaller sub-tasks.
Avoid trying to parallelize tasks that are inherently sequential or involve frequent, small data transfers.
