Dr Giuseppe Barca

Dr Barca is a Lecturer in High-Performance Computing (HPC) in the Research School of Computer Science (RSCS) at the Australian National University (ANU). He also leads the GPU development for the GAMESS Exascale Computing Project.

 

Dr Barca holds a Bachelors' (summa cum laude) and a Masters' Degree (summa cum laude) in Chemical Engineering from the University of Salerno in Italy. His Masters' Degree was awarded with a Honor Mention to the academic career. Dr Barca obtained his PhD in Computational Quantum Chemistry from the ANU, working under the supervision of Prof. Peter Gill. His PhD focused on the development of new algorithms in computational chemistry. From 2017 to 2018, Dr Barca worked as a Postdoctoral Fellow in the Research School of Chemistry at the ANU on the development of massively parallel approaches in computational chemistry. In 2018, he took the role of Research Fellow in HPC at the RSCS under Prof. Alistair Rendell, and joined the GAMESS ECP group under Prof. Mark Gordon at the Iowa State University (Ames Lab). In 2020, Dr Barca started his independent career as a Lecturer in HPC at the RSCS. 

 

Dr Barca's main research focus is the development of high-performance computational science algorithm for cutting-edge HPC systems, such as exascale supercomputers.

 

Dr Barca is a developer of both the Q-Chem and GAMESS quantum chemistry software packages. 

Our group works on the development of novel computational science algorithms designed for efficient execution on cutting-edge high-performance computing platforms. At the present moment, this includes, and is particularly relevant to, exascale systems. 

 

We are particularly interested in devising simulation solutions that enable to push the edge of what is currently possible in science and innovation.

 

Targeting the algorithms that underpin computational science software, our research impacts a broad spectrum of application areas. Current application foci include computational chemistry, material science, machine learning and applied mathematics.
