HIGH PERFORMANCE COMPUTING


Tech Focus: Memory and processors


A ROUND-UP OF THE LATEST PROCESSING AND MEMORY TECHNOLOGIES


The drive for faster processing and increases to memory


bandwidth has driven increases in computing performance. The HPC market, in particular, has long been dominated by a single vendor, and so X86 systems based on Intel CPUs have become the standard. However, in recent years new technologies have arisen both in the form of competition for X86 systems from AMD and other processing technologies such as Intel or IBM Power. This is also further


complicated by increasing demand for AI/ML workloads which often require highly parallel computing elements such as GPUs or FPGA. Increasingly HPC systems are built using heterogeneous components to support the convergence of HPC and AI using the same computing platform. Accelerator technologies


can, in some cases, provide huge amounts of computing performance with some configurations of eight GPUs in a single server. This drive for low-power CPUs and high-power accelerators is continuing in both HPC and AI/ML/. Big profile supercomputing contracts for both AMD and Arm in the last 18 months demonstrate
