Parallelising Compiler for Green Multicore Computing

Professor Hironori Kasahara ( Waseda University )

High performance and low power, or green, computing is essential for various ICT products from smartphones, self-driving vehicles, cancer treatment systems to cloud and High-Performance servers. To realise these systems, a low-power, high performance, and user-friendly multicore and its compiler are key technologies. This talk introduces "OSCAR (Optimally Scheduled Advanced Multiprocessor)" multicore compiler, which has been researched for 35 years in Waseda University, based on "green multigrain parallelisation" based on coarse-grain task parallelization and loop parallelisation, global data locality optimization, automatic power reduction control using DVFS, clock and power gating, software cache coherent control, and automatic local memory management for hard real-time control applications. Performance and power evaluation on various multicores, such as Intel, ARM, IBM, Fujitsu, Renesas, Infineon, and RISC V, are also shown in the talk.
