PPoPP stands for ACM SIGPLAN Symposium on Principles and Practice of Parallel Programming, which is the main forum for leading work on all aspects of parallel programming.Includes theoretical foundations, techniques, languages, compilers, runtime systems, tools, and practical experience. In the context of this workshop, "Parallel Programming" covers work on concurrent and parallel systems (multi-core, multi-threaded, heterogeneous, clustered and distributed systems; grids; data centers; clouds and large-scale machines). Given the rise of parallel architectures in consumer markets (desktops, laptops, and mobile devices) and data centers, PPoPP is particularly interested in handling new parallel workloads and problems that arise in extreme-scale applications or cloud platforms, as well as techniques and tools that make parallel programming more efficient or move towards better cooperation with these emerging architectures.
