Continuous improvements in semiconductor fabrication density are enabling new classes of System-on-a-Chip (SoC) architectures that combine extensive processing logic/processing with high-density memory. Such architectures are generally called Processor-in-Memory or Intelligent Memory and can support high-performance computing by reducing the performance gap between the processor and the memory. This architecture combines various processors in a single system. These processors are characterized by their computational and memory-access capabilities in performance and energy consumption. Two main problems addressed here are how to improve the performance and reduce the energy consumption of applications running on Processor-in-Memory architectures. Accordingly, a novel strategy must be developed to identify the capabilities of the different processors and dispatch the most appropriate jobs to them to exploit them fully. Accordingly, this study proposes a novel automatic source-to-source parallelizing system, called SAGE, to exploit the advantages of Processor-in-Memory architectures. Unlike conventional iteration-based parallelizing systems, SAGE adopts statement-based analytical approaches. The strategy of the SAGE system, which decomposes the original program into blocks and produces a feasible execution schedule for the host and memory processors, is also investigated. Hence, several techniques including statement splitting, weight evaluation, performance scheduling and energy reduction scheduling are designed and integrated into the SAGE system to automatically transform Fortran source programs to improve the performance of the program or reduce energy consumed by the program executed on Processor-in-Memory architecture. This thesis provides detailed techniques and discusses the experimental results of real benchmarks which are transformed by SAGE system and targeted on the Processor-in-Memory architecture.
