POSTDOCTORAL APPOINTEE - COMPUTER SCIENCE

The Argonne Leadership Computing Facilitys (ALCF) mission is to accelerate major scientific discoveries and engineering breakthroughs for humanity by designing and providing world-leading computing facilities in partnership with the computational science community. We help researchers solve some of the worlds largest and most complex problems with our unique combination of supercomputing resources and computational science expertise.

The Mathematics and Computer Science Division (MCS) and ALCF are looking for a postdoctoral appointee to perform research and development on performance characterization and optimization of HPC applications on exascale systems (i.e. Aurora). Exascale systems, and Aurora in particular, exhibit complex memory and device topologies including multiple processors, accelerators (GPUs), and memory types (HBM) connected by non-uniform on-node interconnect. How to best map an HPC application (binding) on such topologies, and further place and move data among the topology is still an open research question, usually tackled by application performance specialists by hand. To ease this process, we are interested in the design of performance characterization methods that combine programming-model level tracing, automated search policies, and learned performance models. The role of this postdoc would be to act as a bridge between application developers, performance experts at ACLF and researchers at MCS to design and provide practical tooling to the community to better understand how applications map to and use Aurora nodes. The work will take place in a multi-disciplinary environment and will offer opportunities to interact with a wide range of talents from the whole spectrum of HPC research.

In this role you can expect to :

• Present and publish your work at major symposia and journals
• Research Profiling / Tracing methods for accelerated HPC applications
• Develop models of the impact of memory utilization on performance
• Design automated optimization policies
• Work together with application developers to ensure optimization sustainability
• Position Requirements
