Benchmarking and Configuration Guide

The Benchmarking and Configuration Guide helps you evaluate and test GDS functionality and performance by using sample applications.

NVIDIA® GPUDirect® Storage (GDS) is the newest addition to the GPUDirect family. GDS enables a direct data path for direct memory access (DMA) transfers between GPU memory and storage, which avoids a bounce buffer through the CPU. This direct path increases system bandwidth and decreases the latency and utilization load on the CPU.

The purpose of this guide is to help the user evaluate and test GDS functionality and performance by using sample applications. These applications can be run after you set up and install GDS and before you run the custom applications that have been modified to take advantage of GDS.

Refer to the following guides for more information about GDS:

• Design Guide

• Overview Guide

• cuFile API Reference Guide

• Release Notes

• Best Practices Guide

• Troubleshooting Guide
