Abstract:  Computational Materials Chemistry

Chemistry is small and fast. The atomic details underlying a specific chemical process or contributing to make a specific material more stable than others may not be easy to access with experimental techniques. 

Computational methods based on quantum and classical physics are nowadays able to address chemical complexity and provide atomic information that are otherwise unaccessible. They are powerful tools to assist with interpreting experiments, providing quantitative support to qualitative observations, making predictions and designing new materials and chemical processes. 

This talk will provide a general introduction to computational materials science for broad audience - where does this field come from, where are we now, where do we want to go. Specific examples and applications will be taken from the work of  Dr. Demichelis’ group, who are using Australia’s latest supercomputing facilities at NCI and at Pawsey Centre to investigate mineral structure and crystal growth.

You’ll also learn about MathWorks’ cloud options and the advantages they offer across the development stages of a system based on AI. Through a case study of training, tuning, and deploying a semantic segmentation model, you’ll hear about the following topics:

  • Managing data efficiently
  • Provisioning MATLAB on AWS®—ready-made for deep learning with NVIDIA® GPUs
  • Scaling to GPU cloud compute clusters
  • Deploying models for unlimited accessibility

You’ll also learn about the following capabilities:

  • Using MATLAB Parallel Server™ on AWS for multi-GPU computing
  • Deploying the MATLAB Production Server™ pay as you go (PAYG) environment on Azure®



Dr Benjamin Joecker - UNSW Sydney

31 August 2021 at 11:00am AEST

As a researcher in Professor Andrea Morello's group, Benjamin and his UNSW peers are setting out to design and build a large-scale quantum computer, a device that uses quantum mechanics to solve otherwise intractable computational problems. The group was the first to demonstrate a qubit, the smallest building block of a quantum computer, in silicon, which paved the way for CMOS foundry compatible approaches pursued today. 

Efficient models for the design of a donor-based quantum computer in silicon

Last year, the tech giant Google has made headlines by showing that a quantum computer can solve a problem intractable for even the fastest supercomputers. Research in Australia today is focused on qubits, the smallest building block of a quantum computer, in silicon to pave the way for a foundry compatible approach. While silicon is the preferred material for scaling, its crystal structure plays a crucial role for the processor layout. A successful design requires a good understanding of the system and accurate models. 

Simulating quantum systems is a formidable task, one of the reasons Richard Feynmann originally saw the need to build a quantum computer. Many approaches are computationally heavy and are unfit to produce the large data sets needed to find optimal qubit configurations, while others have relied on unjustified approximations. In this talk, I will show that our multi-valley effective mass theory can efficiently model donor-based qubits in silicon with high accuracy. Full configuration interaction simulations on a compact but precise basis set allowed us to show the scalability of this qubit implementation and provide invaluable data for future chip designs.

How can high-performance computing help design more efficient jet engines: physical insight and machine learning

CFD predictions are becoming increasingly important in the design of aircraft engines because correlation-based methods are unable to further improve efficiency and laboratory experiments with the required fidelity are prohibitively expensive and often cannot provide the details needed.

This presentation will show how physical insight relevant to designers can be extracted from high-fidelity simulations enabled by the latest HPC systems. It will also discuss how the HPC-generated data can be used to develop better predictive models using a machine-learning approach that is based on gene-expression programming. It will be shown that the machine-learnt models outperform traditional models both for the cases they were trained on and for cases not seen before.
