Pipelining data transfers with OpenACC
Jeff Larkin NVIDIA, Santa Clara, CA, United States
Abstract
The purpose of this chapter is to introduce asynchronous programming with OpenACC, particularly in regards to a technique known as pipelining. This chapter will accelerate an existing OpenACC code by enabling the overlap of computation and data transfers.
At the end of this chapter the reader will have an understanding of:
• Asynchronous execution within OpenACC
• Pipelining as a technique to overlap data transfers with computation
• How to use the OpenACC routine directive.
