OSCAR Compiler for Automatic Multigrain Parallelization, Memory Optimization and Power Reduction for Multicore Systems

To improve processing performance and reduce power consumption, multicore processors have been widely used in embedded systems like a smartphone, self-driving cars, and IoT to high-performance systems like cloud servers and supercomputers. However, to realize efficient parallel processing of a target application program, parallelization of the program and memory usage optimization require long time periods and large cost. This talk introduces OSCAR (Optimally SCheduled Advanced MultiprocessoR) compiler allows users to have efficiently parallelized and memory optimized parallel programs for various multicores available in the market automatically in a short time and low cost. This short talk includes technical demos by the OSCAR compiler that gives us scalable performance improvement and power reduction for:

・scientific applications like earthquake simulation and 3D FFT,
・medical applications like heavy particle cancer therapy and capsule inner cameras,
・industry applications like automotive hard-realtime engine control and MATLAB/Simulink model based designed programs, and
・soft-realtime multimedia programs like H.264 and Optical flow

on various homogeneous and heterogeneous multicores from Intel, IBM, Fujitsu, ARM, Infineon, and Renesas multicore processors.
