The field of High Performance Computing lies at the crossroad of a number of disciplines and skill sets. Correspondingly, for someone to be successful at using HPC in science requires at least elementary knowledge of and skills in all these areas. The series "The Art of High Performance Computing" brings together the components that make up the toolbox of a computational scientist.
Volume 2 "Parallel Programming" covers the two major systems in HPC: MPI for distributed memory, and OpenmP for shared memory programming. Both are covered in great detail with many programming examples. Shorter sections can serve as an introduction to some other parallel systems such as Sycl and Kokkos.
