Job description

AI + HPC hardware performance researcherWhat you will doYou will investigate software-hardware codesign innovations for next-gen artificial intelligence high performance computing systems.The Compute System Architecture Unit (CSA) at imec is researching next-generation large-scale heterogeneous computer architectures. The team is responsible for workload characterization, runtime management, performance modeling, architecture simulation and prototyping for future computer systems and their applications, to reach multiple orders of magnitude better performance, energy-efficiency, and total-cost-of-ownership.We are looking for an AI + HPC hardware performance researcher to innovate across layers of the computing stack, from application to semiconductor technology innovation and everything in between. You work closely with other experts from different fields to identify codesign solutions and to build the infrastructure required to evaluate them. This position plays a key role in our mission to shape the future of high performance computer architecture.You will:

• Research various solutions to enable the next large-scale-high-performance computing clusters. The role spans over various layers from workload characterization, resource management, system architecture, and microarchitecture.
• Develop performance (+power/TCO/emissions) models for future hardware at various levels of detail to identify bottlenecks and propose new solutions that alleviate the bottlenecks.
• Capture the relevant workload characteristics of the use of AI in HPC applications, as inputs to hardware models.
• Analyze performance on existing systems to validate and calibrate hardware models
• Collaborate across the company to guide the direction of HPC HW/SW codesign based on the top HW issues and SW performance limiters generated from the models and characteristics.
• Model features and configurations that improve performance, power, total cost of ownership and emissions.
