International Journal of Parallel Programming, one of the oldest journals in the field, published continuously for over 25 years, is a forum for the publication of peer-reviewed, high-quality original papers in computer science, focusing specifically on parallel computing systems. Such systems are characterized by the coexistence over time of multiple coordinated activities. The journal publishes both original research and survey papers. Fields of interest include: embedded systems to high performance supercomputing, high-level languages, optimizations, parallel and distributed systems, programming support systems, pragmatic considerations, architectural characteristics, software engineering aspects, advances in parallel algorithms, performance studies, and application studies that significantly advance the state of the art.
