Scope:
PPoPP is the premier forum for leading work on all aspects of parallel and performance programming, including theoretical foundations, techniques, languages, compilers, runtime systems, tools, applications, and practical experience. This symposium focuses on improving the programming productivity and performance engineering of all concurrent and parallel systems – multicore, multi-threaded, heterogeneous, clustered, and distributed systems, grids, accelerators such as ASICs, GPUs, FPGAs, data centers, clouds, large scale machines, and quantum computers. PPoPP is also interested in new and emerging parallel workloads and applications, such as artificial intelligence and large-scale scientific/enterprise workloads.

Specific topics of interest include (but are not limited to):
* Languages, compilers, and runtime systems for parallel programs
* Parallel programming frameworks and domain-specific languages
* Parallel programming for emerging hardware, including AI accelerators, processor-in-memory, programmable logic, and non-volatile memory technologies
* High-performance libraries
* Parallel programming for deep memory hierarchies including nonvolatile memory
* Parallel algorithms
* Parallel applications including scientific computing and enterprise workloads
* Artificial intelligence and machine learning for parallel systems, including their use in system design, optimization, and runtime decisions
* Development, analysis, or management tools
* Performance analysis, debugging and optimization
* Productivity tools for parallel systems
* Software engineering for parallel programs
* Parallel programming theory and models
* Formal analysis and verification
* Concurrent data structures
* Synchronization and concurrency control
* Fault tolerance for parallel systems
* Middleware for parallel systems
