Reduction is a common parallel pattern that reduces several values to a single value. For example, a summation reduction adds the values in an array to get a single sum. Finding the minimum or maximum value in an array, or the locations of those values, are also reduction operations.

SYCL* provides a built-in reduction operator that can be used in parallel kernels. The oneAPI DPC++ Library (oneDPL) provides functions for reduction operations. There are valid reasons for using either approach.

This webinar:

  • Uses code samples to illustrate the SYCL reduction operator and oneDPL reduction functions
  • Discusses the relative merits of each approach in terms of coding and data-transfer complexity, and separation of concerns
