TensorToolit is a high-performance tensor basic operation library written in C++. It serves as the foundation for tensor network algorithms (like Density Matrix Renormalization Group, Project Entanglement Pair State) and provides essential functionalities such as tensor contraction, transpose, and more.
TensorToolit offers the following key features:
- Abelian Quantum Numbers
- MPI Parallelization Support
- Fermionic Tensors' Support
Please note that the project requires the following dependencies to be installed in order to build and run successfully:
- C++17 Compiler
- CMake (version 3.12 or higher)
- Intel MKL or OpenBlas
- MPI
- Boost::serialization, Boost::mpi (version 1.74 or higher)
- GoogleTest (if testing is required)
Clone the repository into a desired directory and change into that location:
git clone https://github.com/QuantumLiquids/TensorToolit.git
cd TensorToolit
Using CMake:
mkdir build && cd build
cmake ..
make -j4 && make install
You may want to specify CMAKE_CXX_COMPILER as your favorite C++ compiler,
and CMAKE_INSTALL_PREFIX as your install directory when you're calling cmake

TensorToolit is built upon the foundation laid by the GraceQ/tensor project. While initially inspired by GraceQ/tensor, TensorToolit expands upon its capabilities by adding additional basic tensor operations, improving performance, and most importantly, introducing support for MPI parallelization. We would like to express our gratitude to the following individuals for their contributions and guidance:
- Rong-Yang Sun, the author of GraceQ/tensor, for creating the initial framework that served as the basis for TensorToolit.
- Yi-Fan Jiang, providing me with extensive help and guidance in writing parallel DMRG
- Hong Yao, my PhD advisor. His encouragement and continuous support of computational resources played crucial roles in the implementation of parallel DMRG in TensorToolit.
- Zhen-Cheng Gu, my postdoc advisor, one of the pioneers in the field of tensor network.
Their expertise and support have been invaluable in the development of TensorToolit.
