VMC-PPO

• Parallel Program Optimization for VMC• Goal– To establish a high performance parallel

optimization compiler to parse the current source codes and analysis with advanced optimization algorithm for generating optimized parallel code based on OpenMP

VMC-PPO (cont.)

VMC-PPOSP4/VMC-SYNSP4/VMC-SYN SP7/VMC-TMSSP7/VMC-TMS

System Architecture

Current Status

• Done– TBB porting on ARM11MPCORE – OpenMP porting on ARM11MPCORE– Loop parser– Dependency analyzer– Array detection– Control/Loop Optimization

• Loop fusion• Loop fission• Loop splitting• Loop unroll

– Auto-Parallelization

Achievement applicability

Technique superiority

Time Frame

Future Plane

• Integrate with other sub-systems • Survey Advanced Optimization methods• Auto tuning

• Get basic information about a target application’s performance by HPCToolkit/gprof

• Automatically decide if loops should be parallelized or not

The End!
