Benchmarking GPUs: Measuring Throughput between CPU and GPU
This article was inspired by a LinkedIn post by Dennis Kennetz . The CPU to GPU bandwidth check is available on GitHub which uses a specific flow to assess the data transfer rates. Like many in the industry, my focus is on AI and ML workloads and how we can improve efficiencies and performance using DRAM, CXL, CPU, GPUs, and software improvements.
In the rapidly evolving landscape of artificial intelligence (AI) and machine learning (ML), the ability to process vast amounts of data efficiently is paramount. As AI models grow in complexity and size, the demand for high-performance computing resources intensifies. At the heart of this demand lies the crucial task of optimizing data transfers between various components of a computing system, particularly from DRAM, CPU, and emerging technologies like CXL (Compute Express Link) to and from the GPU.
