Research Statement

The Parallel Processing Institute (PPI) conducts research in all aspects of computer systems and architectures, with a primary focus on parallel acceleration and optimization, system software, programming model, runtime and computer architecture for multicore and distributed systems. Our research also involves other disciplines such as large-scale data processing and cloud computing. The research themes of PPI are improving the performance scalability, energy efficiency and dependability of mobile, centralized and distributed computer systems.
