# Implementation

Start with the project architecture for compiler, Runtime and backend ownership.
The topic references below describe specialized subsystems within those same
boundaries; they do not replace the user-facing programming guides.

For source syntax, see the [SIMT DSL](../dsl.md) and
[Tile programming](../tile/index.md). For measured behavior rather than design
intent, see [performance and validation](../performance/index.md).
