C++ and Fortran Tools for Building and Optimizing Software across Architectures
Intel® oneAPI Toolkit is a core set of tools and libraries for developing optimized software that scales across modern systems.
It supports development needs spanning client and edge applications through to large-scale, distributed systems.
The toolkit provides standards-based compilers, domain-specific performance libraries with drop-in acceleration, and profiling, design, and debugging tools. These capabilities help developers build, optimize, and deploy applications efficiently.
It features an industry-leading C++ compiler with support for SYCL*, among other standards-based programming models.
Get started with this core set of tools and libraries for building, optimizing, and scaling software across diverse architectures.
Submit questions, problems, and other technical support issues through direct and private interactions with Intel engineers.
"Intel's oneAPI toolkit has demonstrated powerful performance and good compatibility in GeoEast* software applications, and has provided us with important help in the further exploration of heterogeneous computing." – BGP Inc.
Add-ons
Some oneAPI tools and libraries are available as separate downloads and can be added as needed. These components integrate with the oneAPI toolchain but are not included in the default Intel oneAPI Toolkit installers.
Design code for efficient vectorization, threading, and offloading to accelerators.
Implement Partitioned Global Address Space (PGAS) programming for host-initiated and device-initiated operations.
Intel® oneAPI Data Analytics Library (oneDAL)
Boost machine learning and data analytics performance.
