The Vienna Ab initio Simulation Package (VASP) is a well-known and largely used software package for performing DFT calculations. VASP requires a significant amount of computing resources and was ranked top 5 used applications on NSCC (National Supercomputing Centre) in terms of CPU hours. Starting from version 6.2.0, VASP is officially capable of acceleration by GPU through the OpenACC port.

I am a researcher at the Singapore Synchrotron Light Source of NUS, primarily working on experimental projects where we study the electronic band structure of various novel and functional materials by employing Spin- and Angle-Resolved Photoemission Spectroscopy (Spin-ARPES).

Reforesting degraded lands is one of the most promising nature-based climate solitions (NCS), with over 850 million hectares of reforestation potential worldwide. Proponents of reforestation point to the importance of forests in intensifying the hydrological cycle, increasing precipitation recycling and water yield. However, studies also show that reforesting drier regions can increase evapotranspiration and reduce the water yield, negatively impacting the local ecosystem and communities.

Passenger thermal comfort in automotive vehicles is an important factor that determines a commuter’s overall experience. Such an experience is provided for by an efficient HVAC (Heating, Ventilation and Air-Conditioning) system which distributes cool air throughout a vehicle. It is, therefore, appropriate to conduct a computational analysis of a HVAC system for the vehicle in order to study its steady-state temperature and air velocity profile.

The researchers from the Climate and Water Research cluster at the Tropical Marine Science Institute (TMSI) use the National Supercomputer Centre’s (NSCC’s) supercomputing resources to investigate how the climate and weather impact the region, by using complex computer models at high spatial resolutions of 400m over the entire Singapore.

Two-phase chemically reacting flows widely exist in engineering practise, such as propulsion system, power generation, industrial hazard prevention, and nanomaterial flame synthesis. Normally they include dispersed droplets or particles in a continuous gas phase field, where elementary chemical reactions proceed. Comprehensive interactions occur between these two phases, which however renders it difficult to accurately articulate how the dispersed droplets behave and influence the reacting flow dynamics. As a research team in NUS, we aim to unveil the underlying interactive mechanisms behind the chemically reacting flows based on high-fidelity numerical simulations and advanced data analysis method.

Recent trends indicate that the proliferation of AI/ML applications has a positive effect on the adoption of HPC technologies by enterprises. We will analyse why that is happening and how it will benefit the HPC practitioners. This synergistic development of AI and HPC has also led to the renaming of this periodical to HPC-AI Newsletter.
