How GPUs Are Embedded in the HPC Landscape
HPCWire, Monday, September 23rd, 2024
Grasping the basics of Graphics Processing Unit (GPU) architecture is crucial for understanding how these powerful processors function, particularly in high-performance computing (HPC) and other demanding computational tasks.
In a previous article, Understanding the GPU -The Catalyst of the Current AI Revolution, the basic concepts of a GPU were presented. This article continues with a discussion of the following topics:
- The basic structure of a GPU
- Explanation of multiply-add operation and its importance
- Why GPUs are good for HPC and AI computing
A single GPU is made up of multiple Processor Clusters (PC), each of which houses several Streaming Multiprocessors (SM). Each SM contains a layer-1 instruction cache(L1) that closely interacts with its cores...
