How JAX Shards a Computation Across a Mesh

Explore how JAX improves computation placement with Auto, Explicit, and Manual methods. Learn about their impact on correctness in this detailed overview.

JAX addresses a critical issue in computation placement by offering three methods: Auto, Explicit, and Manual. This article explores each method with real examples from an 8-device run, showcasing how the compiler has evolved into a partner for correctness.
