Intel® oneAPI DPC++ Library(Beta)

High-Productivity APIs for Heterogeneous Computing

The Intel® oneAPI DPC++ Library is a companion to the Intel® oneAPI DPC++ Compiler and provides an alternative for C++ developers who create heterogeneous applications and solutions. Its APIs are based on familiar standards—C++ STL, Parallel STL (PSTL), Boost.Compute, and SYCL*—to maximize productivity and performance across CPUs, GPUs, and FPGAs.

  • Allows explicit use of the C++ STL API within accelerated DPC++ kernels
  • Streamline cross-architecture programming with Boost.Compute and PSTL algorithm extensions
  • Increase the successful application of parallel algorithms with custom iterators
