Intel® oneAPI Base Toolkit

Multiarchitecture C++ and Python* Developer Tools for Open Accelerated Computing

Heterogeneous Development across CPUs, GPUs, and FPGAs

The Intel® oneAPI Base Toolkit (Base Kit) 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 that implements SYCL*, 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.

Add-on Toolkits for Specialized Workloads

You can complement the Base Kit with additional toolkits.
