PyPTO Coding

Use this chapter when writing or reviewing PyPTO-Lib kernels.

• PyPTO Coding Style is the canonical reference for kernel forms, scopes, loops, tensor operations, tiling, naming, and source layout.
• CCE Extern Kernel covers hand-written mixed cube and vector kernels called through pl.jit.extern, including runtime, ABI, synchronization, and validation constraints.

Start with the coding style for every kernel change. Use the extern-kernel page only when the implementation crosses from PyPTO into hand-written CCE code.
