Unlocking High-Performance Computing: How InfiniBand Accelerates AI, ML, and Data Science Workflows

Table of contents

InfiniBand is a high-performance, low-latency networking technology primarily used in data centers and high-performance computing (HPC) environments. It is designed to facilitate fast data transfer between servers, storage systems, and other network devices. InfiniBand supports both communication and storage protocols, making it a versatile choice for various applications, including artificial intelligence (AI), machine learning (ML), and data science. Its Architecture is based on a switched fabric topology, which allows for scalable and efficient data transfer, making it ideal for environments that require high throughput and low latency.

Origins and History of InfiniBand

InfiniBand was developed in the late 1990s as a collaborative effort by several technology companies, including Intel, IBM, and Microsoft, to address the limitations of existing networking technologies. The InfiniBand Trade Association (IBTA) was formed in 1999 to oversee the development and standardization of the technology. The first InfiniBand products were introduced in the early 2000s, and since then, it has evolved to support higher data rates and more advanced features. InfiniBand has become a staple in HPC environments, powering some of the world's fastest supercomputers.
