Minisymposium Presentation
Enabling the Seamless Execution of Hybrid Quantum-HPC Workflows on Classical HPC Systems
Presenter
Aniello works as a senior research engineer in the EMEA research lab at HPE, where he is responsible for the center ofexcellence collaboration with KAUST (Saudi Arabia) among other activities in the field of supercomputing and is also involvedin pre-sales as an expert application analyst for European procurements.Aniello studied physics at ETH Zurich, followed by a PhD on simulation of semiconductor devices and postdoctoral researchin computational microscopy. He joined Cray in 2011 as an application analyst at the HLRS in Stuttgart (Germany), where he supported users of the Cray systems and organized workshops in various European sites and eventually joined the Cray EMEA research lab. His expertise and interests reside in the development and optimization of scientific applications for supercomputers ranging from state-of-the-art numerical approaches to emerging areas such as machine learning and AI as well as quantum computing.
Description
Driven by the rapid development of intermediate-scale quantum devices, hybrid classical-quantum workflows have come into the focus of many leading HPC service providers including clouds and supercomputing centers. This interest is enhanced by promising early results such as variational methods for quantum chemistry and combinatorial problems but also more widely applicable approaches like circuit knitting. In this talk, we summarize experiences from early attempts to combine quantum devices and an HPE-Cray EX supercomputer by means of simple proxy applications, and how to execute a hybrid HPC-QC workflow efficiently using state-of-the-art frameworks such as the message passing interface and the Slurm job scheduler.
