Beschreibung

This weekly workshop series is jointly organized by NHR@FAU (https://hpc.fau.de/teaching/tutorials-and-courses/), NHR@TUD (https://tu-dresden.de/zih/hochleistungsrechnen/nhr-training) and NVIDIA DLI (http://www.nvidia.com/dli). It covers the following DLI courses:

• Fundamentals of Accelerated Computing with CUDA C/C++ (https://learn.nvidia.com/courses/course-detail?course_id=course-v1:DLI+C-AC-01+V1)
• Accelerating CUDA C++ Applications with Multiple GPUs (https://learn.nvidia.com/courses/course-detail?course_id=course-v1:DLI+C-AC-04+V1)
• Scaling CUDA C++ Applications to Multiple Nodes (https://learn.nvidia.com/courses/course-detail?course_id=course-v1:DLI+C-AC-07+V1)

Please indicate which parts you want to attend when registering.

Date and Time

The courses will be held online on September 18th, September 25th and October 2nd, from 9 am to 5 pm.

Prerequisites

A free NVIDIA developer account is required to access the course material. Please register before the training at https://learn.nvidia.com/join (https://learn.nvidia.com/join).

Part 1

• Basic C/C++ competency, including familiarity with variable types, loops, conditional statements, functions, and array manipulations
• No previous knowledge of CUDA programming is assumed

Parts 2 and 3

• Successful attendance of Part 1 (Fundamentals of Accelerated Computing with CUDA C/C++ (https://hpc.fau.de/teaching/tutorials-and-courses/#collapse_3)) or equivalent experience implementing CUDA C/C++ applications, including
  • memory allocation, host-to-device and device-to-host memory transfers,
  • kernel launches, grid-stride loops, and
  • CUDA error handling. 
• Familiarity with the Linux command line.
• Experience using Makefiles to compile C/C++ code.

Learning Objectives

Day 1

At the conclusion of the workshop, participants will have an understanding of the fundamental tools and techniques for GPU- accelerating C/C++ applications with CUDA and be able to:

• Write code to be executed by a GPU accelerator
• Expose and express data and instruction-level parallelism in C/C++ applications using CUDA
• Utilize CUDA-managed memory and optimize memory migration using asynchronous prefetching
• Leverage command-line and visual profilers to guide your work
• Utilize concurrent streams for instruction-level parallelism
• Write GPU-accelerated CUDA C/C++ applications, or refactor existing CPU-only applications, using a profile-driven approach

Day 2

At the conclusion of the workshop, you will be able to:

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

Day 3

At the conclusion of the workshop, you will be able to:

• Use several methods for writing multi-GPU CUDA C++ applications,
• Use a variety of multi-GPU communication patterns and understand their tradeoffs,
• Write portable, scalable CUDA code with the single-program multiple-data (SPMD) paradigm using CUDA-aware MPI and NVSHMEM,
• Improve multi-GPU SPMD code with NVSHMEM’s symmetric memory model and its ability to perform GPU-initiated data transfers, and
• Get practice with common multi-GPU coding paradigms like domain decomposition and halo exchanges.

Language

The courses will be held in English.
