High-Performance Computation on Sparse Data Structures [Paper] [Video] [Language Details]

Examples

Updates

# CPU only. No GPU/CUDA needed
python3 -m pip install taichi-nightly

# With GPU (CUDA 10.0) support
python3 -m pip install taichi-nightly-cuda-10-0

# With GPU (CUDA 10.1) support
python3 -m pip install taichi-nightly-cuda-10-1

• (Oct 30, 2019) v0.0.72 released. Update highly recommended.
  • LLVM GPU backend now as fast as the legacy (yet optimized) CUDA backend. To enable, export TI_LLVM=1;
  • Bug fixes: LLVM struct for list generation.
• (Oct 29, 2019) v0.0.71 released. LLVM GPU backend performance greatly improved. Frontend compiler now emits readable syntax error messages.
• (Oct 28, 2019) v0.0.70 released. This version comes with experimental LLVM backends for x86_64 and CUDA (via NVVM/PTX). GPU kernel compilation speed is improved by 10x. To enable, update the taichi package and export TI_LLVM=1.
• (Oct 24, 2019) Python wheels (v0.0.61) released for Python 3.6/3.7 and CUDA 10.0/10.1 on Ubuntu 16.04+. Contributors of this release include Yuanming Hu, robbertvc, Zhoutong Zhang, Tao Du, Srinivas Kaza, and Kenneth Lozes.
• (Oct 22, 2019) Added support for kernel templates. Kernel templates allow users to pass in taichi tensors and compile-time constants as kernel parameters.
• (Oct 9, 2019) Compatibility improvements. Added a basic PyTorch interface. [Example].
• (Oct 7, 2019) Released experimental python 3.6 wheels on Linux (tested on Ubuntu 16.04/18.04) for those who are eager to try without building from source. More stable releases are coming in a few days. To install them:

Notes:

• You still need to clone this repo for demo scripts under examples. You do not need to execute install.py. After installation using pip you can simply go to examples and execute, e.g., python3 mpm.py.
• Make sure you have clang-7. On Ubuntu 18.04 you can install it with sudo apt-get install clang-7. See here for installing clang-7 on Ubuntu 16.04. You will also need g++-7 on Ubuntu16.04 (for c++17 headers). To install:

# Ubuntu 16.04 only
sudo apt-get install -y software-properties-common
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt update
sudo apt install g++-7 -y

• Make sure you clear your legacy Taichi installation (if applicable) by cleaning the environment variables (delete TAICHI_REPO_DIR, and remove legacy taichi from PYTHONPATH) in your .bashrc or .zshrc. Or you can simply do this in your shell to temporarily clear them:

export PYTHONPATH=
export TAICHI_REPO_DIR=

The Taichi Library [Legacy branch]

Taichi is an open-source computer graphics library that aims to provide easy-to-use infrastructures for computer graphics R&D. It's written in C++14 and wrapped friendly with Python.
