Performance Optimization and Porting Tools for Energy-Efficient High Performance Computing Architectures

The ARM processor architecture is poised to be a key technology for energy-efficient high performance computing. An easytouse and robust tool chain for understanding, porting and refactoring existing HPC codes (e.g., SciDAC codes) is essential to unlocking the full potential of ARM in the HPC realm. PMaC Laboratories plans to develop a set of HPC application analysis tools, which requires a non-existent binary instrumentation capability for ARM. To fill this need, PMaC Laboratories is developing an open source binary instrumentation toolkit for the ARM architecture, which can be used to port PMaCs HPC application analysis tool set to ARM. This binary instrumentation toolkit will form the foundation for developing other software tools for porting, debugging and optimizing HPC codes, including DOE codes, to the ARM architecture. Commercial Applications and Other Benefits: The ARM software development tools being created by PMaC Laboratories have commercial applications across high performance computing, Internet scale and cloud computing, and mobile computing. In the case of the latter, the potential exists to enable HPC apps on future tablets and smartphones, where ARM is the predominant architecture.
