Data parallelism has arguably become the most important form of parallel programming. But according to parallel computing expert James Reinders, language support for it has been tucked away in single instruction, multiple data (SIMD) directives like OpenMP* or kernels like OpenCL™ standard or CUDA*.

The result? According to James, exploiting data parallelism is “too much in the weeds” and gets worse when you seek to be portable.

This is why he's excited about Data Parallel C++ (DPC++), a programming language and model that offers developers real advantages, including bringing heterogeneous programming to C++, code reuse from CPUs to GPUs to FPGAs, and cross-platform parallelism performance.

James discusses the developer benefits of DPC++, including:

  • The programming challenges it addresses
  • Key components of DPC++ and the standards it's based on
  • How DPC++ compares to other software development inflection points in history
  • A peek inside his new book focused on DPC++
