“Enabling Efficient and Effective Complex HPC and AI Workflows“
18 February 2025
Abstract
High-end HPC and AI systems are facing several challenges today, two important ones being the increasing use of AI on such systems and concerns about sustainability. Addressing these new challenges is an important part of system design, for both hardware and software. Focusing on software, AI shows up in several ways, as a significant workflow enhancement to traditional simulation workloads and also as a new field of innovation for computation. Sustainability also manifests in several ways, including the desire for reduced energy consumption and the ability to work with the environment. Features such as “free cooling” and “heat reuse” are becoming more desirable.
This talk provides an overview of some of these current challenges along with discussion of potential solutions.
Bio
Mr. Larry Kaplan is a Senior Distinguished Technologist at HPE who has been working on HPC systems for over 30 years. He is currently the Chief Software Architect for HPC and is working on the design and implementation of the software stack for the current and next generations of the HPE Cray Supercomputer product line. Special focus areas for Mr. Kaplan include federated workflows, advanced system and power management, open and modular software ecosystems, and advanced network software stacks from fabric managers and NIC drivers up through communication libraries and programming models. Larry played a significant role in the design of the EX, XC, XE, XT, XMT, and MTA supercomputers, especially in the areas of runtime, operating and supervisory systems, and hardware/software interface. He was also an OS engineer for the BBN ACI TC2000 and GP1000 computers. Past projects have included work in system and application resiliency and both virtual and physical memory management. Mr. Kaplan has a Master’s degree in Computer Architecture from the Courant Institute at NYU and a Bachelor’s degree in Computer Science modified with Electrical Engineering from Dartmouth College. Mr. Kaplan holds over a dozen U.S. patents and has co-authored several papers published in IEEE and other conferences.
