Intel® oneAPI Base Toolkit
No Transistor Left Behind
The Smart Path to Accelerated Computing without the Economic and Technical Burdens of Proprietary Programming Models
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.
