High-performance computing (HPC) has emerged as an essential technology in modern design and development environments. Driven by increased competitive pressures, manufacturers increasingly compete based on their computer-aided engineering (CAE) and HPC infrastructure environments. Deploying and managing HPC infrastructure is challenging, however. HPC clusters are complex and costly to deploy and require specialized skills across multiple domains to manage and maintain them effectively. As a result, engineering teams can spend much of their time managing the HPC environment rather than focusing on more productive work. This can lead to higher costs and longer design cycles due to reduced productivity. This paper will explore this dilemma and explain how turnkey HPC appliances from Altair and Intel can dramatically simplify HPC cluster deployment and management. It will show how the Altair Unlimited™ appliance powered by state-of-the-art Intel® Xeon® processors can reduce simulation time, reduce costs, and improve overall productivity and efficiency.
