HPC Performance Engineer

Agency for Science, Technology and Research – Queenstown

Join the team responsible for Singapore’s new supercomputer. As our HPC Performance Engineer, you are the "engine tuner" for the entire national facility. Your work will ensure that this multi-million-dollar investment runs at peak performance and efficiency for all of Singapore’s key research domains from AI to climate and material science. This is a unique opportunity to tackle diverse performance challenges at a massive scale, profile applications of national importance, and directly influence the design of future national HPC systems.

RESPONSIBILITIES

Conduct performance engineering to large-scale HPC system and application workloads, optimising both the performance and energy efficiency.

Profile and build performance models of the user applications, workflow and scientific software stacks.

Design, develop and implement HPC software best practices and scalable software infrastructure.

Provide HPC and scientific domain advice to users of NSCC systems.

Engage and collaborate with new researchers, communities, and disciplines with computationally intensive requirements.

Assist in the planning and design of future HPC systems, including benchmarking NSCC workloads on various platforms and recommending the most suitable architecture for the research community.

Analyse system and user job data for efficient resource allocation and management.

Develop HPC utilities and automated testing tools for NSCC HPC systems.

Develop HPC user and best practice guides for NSCC HPC systems.

Get up-to-date with scientific domain research development, HPC system and software technology.
