Functions decorated +with ``@ti.kernel`` are kernels that serve as the entry points where +Taichi’s runtime takes over the tasks, and they must be directly +invoked by Python code.

As a +result, calls to these functions are executed on multi-core CPUs +or GPUs. + +Below you can see how simple it is to use the Taichi Lang ``@ti.func`` +and ``@ti.kernel`` decorators to accelerate Python code.

_what-is-taichi: + +******************************************************************** +What is Taichi Lang? +******************************************************************** + +Taichi Lang is an open-source, imperative, and parallel programming language embedded +in Python, designed for high-performance numerical computation and real-time physical +simulation. It uses just-in-time (JIT) compilation frameworks such as LLVM to accelerate +compute-intensive Python code by compiling it into optimized GPU or CPU instructions. + +Features and use cases +==================================================================== + +Taichi Lang allows developers to write concise, high-level algorithms while leaving +performance optimization to Taichi’s compiler. Taichi Lang is widely used in domains such +as fluid dynamics, particle-based simulations, robotics, computer vision, augmented +reality, artificial intelligence, and visual effects for film and gaming. For example, +simulating a cloth falling onto a sphere, a system with tens of thousands of mass +points and springs, can be implemented in Taichi Lang with only a few dozen lines of +Python code due to its data-oriented design and automatic parallelization. + +Taichi Lang also supports advanced techniques such as hierarchical sparse voxel grids for +large-scale simulations, enabling efficient handling of spatially sparse data structures +in 3D visual computing. On ROCm, Taichi Lang is officially supported on AMD Instinct +GPUs, making it a powerful tool for developers who need both flexibility and performance. + + +Why Taichi Lang? +==================================================================== + +- **Built around Python**: Taichi Lang shares almost the same syntax with Python, + which lets you write algorithms with minimal syntax differences. It is also well + integrated into the Python ecosystem, including NumPy and PyTorch. + +- **Flexibility**: Taichi Lang provides a set of generic data containers known + as ``SNode``, an effective mechanism for composing hierarchical, + multi-dimensional fields. This can cover many use patterns in numerical simulation + (for example, `spatially sparse computing `__). + +- **Performance**: With the ``ti.kernel`` decorator, Taichi Lang's JIT compiler + automatically compiles your Python functions into efficient GPU or CPU machine + code for parallel execution. + +- **Portability**: Write your code once and run it everywhere. Taichi + Lang supports most mainstream GPU APIs, such as NVIDIA CUDA and Vulkan. You can + write your code with Taichi Lang on ROCm and use it extensibly. + +- **Additional feature support**: Cross-platform support that includes a Vulkan-based 3D visualizer, + `differentiable programming `__, + `quantized computation `__ (experimental), and many more. diff --git a/readthedocs.yaml b/readthedocs.yaml new file mode 100644 index 0000000000000..3db285f6f772c --- /dev/null +++ b/readthedocs.yaml @@ -0,0 +1,14 @@ +version: 2 + +sphinx: + configuration: docs/conf.py + +python: + install: + -
