In this workshop, PEARC21 conference attendees will learn how to take advantage of oneAPI for modern cross-architecture application development, analysis, and tuning. Attendees will learn Intel’s oneAPI Toolkits are a useful upgrade to the popular and widely used Parallel Studio XE tools, to embrace the vision of oneAPI, making heterogeneous programming open and ubiquitous. The session will educate participants on current resources, oneAPI Toolkits, and development vehicles available to the PEARC21 community. Join us to learn more! NOTE: This session is ideal for research computing system administrators, application specialists, application developers, and other HPC and AI software stakeholders. Speakers: James Reinders, co-author of the recent book on Data Parallel C++ (and nine other HPC focused books), will be joined by other Intel engineers and experts to teach this workshop and answer questions from participants.
