GPU Programming in MATLAB

Chapter 6

Multiple GPUs

Abstract

This chapter covers a hot topic about utilizing multiple GPUs. In this chapter, we present the use of multiple GPUs both on a multicore machine and on different machines. Multiple GPUs are used to improve the performance on task- or data-parallel codes and when working with data that cannot fit in the memory of a single GPU. This chapter includes a variety of examples, both didactical and real-world examples. After reading this chapter, you should be able to:

• understand MATLAB’s GPU programming features for utilizing multiple GPUs.

• execute the same code on different GPUs.

• use multiple GPUs to execute codes when working with data that cannot fit in the memory of a single GPU.

• utilize multiple GPUs ...
