Modernizing the CS Introductory Sequence with Parallel and Distributed Computing (and some AI)

Parallel and distributed computing (PDC) has become pervasive in all aspects of computing, and thus it is essential that students include parallelism and distribution in the computational thinking that they apply to problem solving, from the very beginning. Computer science education is still teaching a 20th century model of algorithmic problem solving, where sequence, branch, and loop are the only organizing principles needed for algorithms. We invest considerable time in showing how best to sequentially process large volumes of data. All computing devices that students use currently have multiple cores as well as a GPU in many cases. Most of their favorite applications use multiple cores and distributed resources. Often concurrency offers simpler solutions than sequential approaches. In this tutorial we overview key PDC concepts and provide examples of how they may naturally be incorporated in early computing classes. We lead participants through plugged and unplugged curriculum modules that have been successfully integrated and tested in existing computing classes at multiple institutions. We also discuss recent efforts at integrating AI methods, including LLMs, into early classes. In addition, we highlight other CDER activities for integration of PDC and AI into undergraduate computing curricula. Additional Information: No equipment or prior PDC experience is required, although a laptop that can run C++, Java and Python is recommended for following along with some code examples if desired.
