Application Development
Application development on openEuler
BiSheng-Autotuner is an automatic compilation and optimization tool that works in conjunction with tunable compilers, such as LLVM for openEuler and GCC for openEuler.
GCC for openEuler builds upon the open source GCC, with a primary focus on optimizing C, C++, and Fortran languages
The LLVM for openEuler compiler is developed based on the open-source LLVM.
ANNC is a compiler focused on accelerating neural network computation. It enhances inference performance for recommendation systems and large models, and supports integration with mainstream open-source inference frameworks.
High Availability
