Instructor-Led Workshop: Fundamentals of Accelerated Computing with CUDA C/C++

NHR Workshop (Online)

Montag, Dienstag, 08., 09. September 2025, jeweils 9 - 13 Uhr

Speaker: Markus Velten

This workshop teaches the fundamental tools and techniques for accelerating C/C++ applications to run on massively parallel GPUs with CUDA^®. You’ll learn how to write code, configure code parallelization with CUDA, optimize memory migration between the CPU and GPU accelerator, and implement the workflow that you’ve learned on a new task—accelerating a fully functional, but CPU-only, particle simulator for observable massive performance gains. At the end of the workshop, you’ll have access to additional resources to create new GPU-accelerated applications on your own.

Agenda

Accelerating Applications with CUDA C/C++
- Learn the essential syntax and concepts to be able to write GPU-enabled C/C++ applications with CUDA:
  - Write, compile, and run GPU code.
  - Control parallel thread hierarchy.
  - Allocate and free memory for the GPU.
Managing Accelerated Application Memory with CUDA C/C++
- Learn the command-line profiler and CUDA-managed memory, focusing on observation-driven application improvements and a deep understanding of managed memory behavior:
  - Profile CUDA code with the command-line profiler.
  - Go deep on unified memory.
  - Optimize unified memory management.
Asynchronous Streaming and Visual Profiling for Accelerated Applications with CUDA C/C++
- Identify opportunities for improved memory management and instruction-level parallelism:
  - Profile CUDA code with NVIDIA Nsight Systems.
  - Use concurrent CUDA streams.
Final Review
- Review key learnings and wrap up questions.
- Complete the assessment to earn a certificate.
- Take the workshop survey.
