OpenACC: Productive, Portable Performance on Hybrid Systems Using High-Level Compilers and Tools
SESSION: OpenACC: Productive, Portable Performance on Hybrid Systems Using High-Level Compilers and Tools
EVENT TYPE: Tutorials
TIME: 8:30AM - 5:00PM

Portability and programming difficulty are two critical hurdles in generating widespread adoption of accelerated computing in high performance computing. The dominant programming models for accelerator-based systems (CUDA and OpenCL) offer the power to extract performance from accelerators, but with extreme costs in usability, maintenance, development, and portability. To be an effective HPC platform, hybrid systems need a high-level programming environment to enable widespread porting and development of applications that run efficiently on either accelerators or CPUs. In this hands-on tutorial we present the high-level OpenACC parallel programming model for accelerator-based systems, demonstrating compilers, libraries, and tools that support this cross-vendor initiative. Using personal experience in porting large-scale HPC applications, we provide development guidance, practical tricks, and tips to enable effective and efficient use of these hybrid systems.
