The Intel oneAPI Base Toolkit is a core set of tools and libraries for developing high-performance, data-centric applications across diverse architectures. It features an industry-leading C++ compiler and the Data Parallel C++ (DPC++) language, an evolution of C++ for heterogeneous computing. Domain-specific libraries and the Intel Distribution for Python provide drop-in acceleration across relevant architectures. Enhanced profiling, design assistance, and debug tools complete the kit. High-performance computing (HPC) is at the core of artificial intelligence, machine learning, and deep learning applications. The Intel oneAPI HPC Toolkit delivers what developers need to build, analyze, optimize, and scale HPC applications with the latest techniques in vectorization, multithreading, multi-node parallelization, and memory optimization. Intel oneAPI HPC Toolkit is an add-on to the Intel oneAPI Base Toolkit, which is required for full functionality. It also includes access to the Intel Distribution for Python, the Intel oneAPI DPC++/C++ Compiler, powerful data-centric libraries, and advanced analysis tools.
