Integrating Parallel and Distributed Computing in Early Computing Classes

Parallel and distributed computing (PDC) has become pervasive in all aspects of computing, so it is essential that students include parallelism and distribution in the computational thinking that they apply to problem solving, from the very beginning of their computing education. With all computing devices that students use currently having multiple cores as well as a GPU in many cases, many students' favorite applications use multiple cores and/or distributed processors. However, we are still teaching them to solve problems using only sequential thinking. Why?
