HIGH PERFORMANCE COMPUTING


Tech focus: networking


A ROUND-UP OF THE LATEST TOOLS FOR SCIENTISTS USING NETWORKING TECHNOLOGIES


With increasing complex challenges in science and


engineering, researchers are looking to larger computing systems that require fast networking to deliver the data they need for their experiments and research projects. Networking companies


provide high-speed access to data which can support high throughput workloads. While the main networking technologies in HPC are based on either Ethernet or InfiniBand, but there are also other technologies that use PCI Express to develop networking fabrics to support other ultra-low latency, high- bandwidth workloads. This is generally based on the use of high-speed real-time systems, clustered databases, general networking, web services and industrial embedded applications. In recent years, the


movement of data – rather than the sheer speed of computation – has become a major bottleneck to large scale or particularly data-intensive HPC applications. This has driven bandwidth increases in interconnect technology, effectively widening the pipe that data uses to travel across the network. The choice to develop a bespoke system or use an

end-to-end solution to support scientific research projects depends on workloads, scale and budget. There are many ways to solve these challenges, but the answer for each organisation will depend on the scale of the challenge and the demand for latency, which inevitably drives the cost of deployment.
