Computationally intensive CUDA^® C++ applications in high-performance computing, data science, bioinformatics, and deep learning can be accelerated by using multiple GPUs, which can increase throughput and/or decrease your total runtime. When combined with the concurrent overlap of computation and memory transfers, computation can be scaled across multiple GPUs without increasing the cost of memory transfers. For organizations with multi-GPU servers, whether in the cloud or on NVIDIA DGX^™ systems, these techniques enable you to achieve peak performance from GPU-accelerated applications. And it’s important to implement these single-node, multi-GPU techniques before scaling your applications across multiple nodes.

This workshop covers how to write CUDA C++ applications that efficiently and correctly utilize all available GPUs in a single node, dramatically improving the performance of your applications and making the most cost-effective use of systems with multiple GPUs.

Learning Objectives

By participating in this workshop, you’ll:

Use concurrent CUDA streams to overlap memory transfers with GPU computation
Utilize all available GPUs on a single node to scale workloads across all available GPUs
Combine the use of copy/compute overlap with multiple GPUs
Rely on the NVIDIA Nsight^™ Systems Visual Profiler timeline to observe improvement opportunities and the impact of the techniques covered in the workshop

Workshop Outline

Introduction (15 mins)	Meet the instructor. Create an account at courses.nvidia.com/join
Using JupyterLab (15 mins)	Get familiar with your GPU-accelerated interactive JupyterLab environment.
Application Overview (15 mins)	Orient yourself with a single GPU CUDA C++ application that will be the starting point for the course. Observe the current performance of the single GPU CUDA C++ application using Nsight Systems.
Introduction to CUDA Streams (90 mins)	Learn the rules that govern concurrent CUDA stream behavior. Use multiple CUDA streams to perform concurrent host-to-device and device-to-host memory transfers. Utilize multiple CUDA streams for launching GPU kernels. Observe multiple streams in the Nsight Systems Visual Profiler timeline view.
Break (60 mins)
Copy/Compute Overlap with CUDA Streams (90 mins)	Learn the key concepts for effectively performing copy/compute overlap. Explore robust indexing strategies for the flexible use of copy/compute overlap in applications. Refactor the single-GPU CUDA C++ application to perform copy/compute overlap. See copy/compute overlap in the Nsight Systems visual profiler timeline.
Multiple GPUs with CUDA C++ (60 mins)	Learn the key concepts for effectively using multiple GPUs on a single node with CUDA C++. Explore robust indexing strategies for the flexible use of multiple GPUs in applications. Refactor the single-GPU CUDA C++ application to utilize multiple GPUs. See multiple-GPU utilization in the Nsight Systems Visual Profiler timeline.
