Quadrants on ROCm documentation
********************************************************************

Quadrants is a multi-platform compiler for physics simulation. You write kernels in
Python and Quadrants lowers them to parallel code for AMD ROCm (HIP),
Vulkan (SPIR-V), Apple Metal, and x86 and ARM64 CPUs. `Genesis <https://rocm.docs.amd.com/projects/genesis/en/docs-26.10/>`__ uses it for the numeric
kernels inside its solvers, collision code, and linear algebra.

Use Quadrants on ROCm to compile Python physics kernels for AMD Instinct GPUs.
A kernel written once lowers to parallel code for the selected architecture.

The project was forked from `Taichi Lang <https://rocm.docs.amd.com/projects/taichi/en/latest/what-is-taichi.html>`__
and is now an independent compiler. It does not aim to stay compatible with upstream Taichi Lang,
as development is led by Genesis AI. This ROCm edition is the
`https://github.com/AMD-Ecosystem/quadrants/tree/rocm10.1.0_r26.10 <https://github.com/AMD-Ecosystem/quadrants/tree/rocm10.1.0_r26.10>`__
branch.

The Quadrants public repository is located at
`https://github.com/AMD-Ecosystem/quadrants <https://github.com/AMD-Ecosystem/quadrants>`__.
