National Computational Infrastructure (NCI)

Brief Introduction and Overview

The National Computational Infrastructure (NCI) stands as Australia's premier high-performance computing, data, and storage organization. It plays a vital role in supporting scientific research, governmental initiatives, and industrial advancements across a wide spectrum of disciplines. NCI's core mission is to significantly enhance the ambition, impact, and overall outcomes of Australian research endeavors, aligning its efforts with national research priorities and the pursuit of scientific excellence. Its advanced resources and expertise empower researchers to tackle complex challenges and push the boundaries of scientific discovery.

Overview

NCI's roots trace back to the Australian Partnership for Advanced Computing (APAC), established in 2001. APAC's infrastructure, initially commissioned at The Australian National University (ANU), laid the foundation for NCI. The transition from APAC to the current NCI collaborative structure commenced in 2007, marking a significant evolution in its capabilities and scope. This collaborative model strengthened its capacity to serve the broader Australian research community.

Key Milestones in NCI's History and Growth:

• 2001: The APAC National Facility was commissioned at The Australian National University (ANU).
• 2007: APAC began its transformation into the current NCI collaborative structure. This marked a shift towards a more integrated and collaborative approach, expanding its reach and impact.

Regulatory Compliance and Licenses

NCI's operations are underpinned by the Australian Government's National Collaborative Research Infrastructure Strategy (NCRIS). This strategic framework provides crucial support for NCI's activities. The organization functions under a formal collaborative agreement involving several key partners: CSIRO, the Bureau of Meteorology, ANU, Geoscience Australia, the Australian Research Council, and a number of leading research-intensive universities and medical research institutes. This collaborative structure ensures a wide range of expertise and resources are leveraged to optimize NCI's services and impact.

High-Performance Computing and Data Services

NCI's core strength lies in its provision of cutting-edge high-performance computing (HPC) and data services. These resources are instrumental in enabling complex scientific simulations, data analysis, and research endeavors across diverse fields.

Main High-Performance Computing Installations:

• Gadi: This flagship system boasts a staggering 9.26 PetaFLOP processing power. This distributed memory cluster comprises 145,152 cores (Intel Xeon Scalable 'Cascade Lake' processors) across 3024 nodes. Its impressive specifications include 160 nodes equipped with four Nvidia V100 GPUs, 567 Terabytes of main memory, 20 Petabytes of fast storage, 47 Petabytes of storage for large data files, and 50 Petabytes of tape storage for archival purposes. Gadi's capabilities enable researchers to tackle computationally intensive problems previously considered intractable.
• Tenjin: A 67 TeraFLOP bespoke high-performance partner cloud, Tenjin provides a scalable and flexible computing environment, complementing the capabilities of Gadi and catering to specific research needs.

Data Services and Storage:

NCI's data services and storage capabilities are equally impressive. It operates the fastest filesystems in the Southern Hemisphere, providing a total capacity exceeding 75 Petabytes. The infrastructure also includes a robust replicated tape-based long-term storage system for archival purposes, ensuring the long-term preservation and accessibility of valuable research data.

Additional Services

Beyond its HPC and storage capabilities, NCI offers a range of additional services designed to support researchers throughout their projects.

Other Services Provided:

• Data Management Expertise: NCI excels in data management, curating and optimizing nationally and internationally significant reference datasets. This includes crucial datasets like CMIP5 and CMIP6, ERA5, Landsat, and Himawari, empowering researchers with access to high-quality, readily available data.
• Cloud Services: NCI provides robust cloud services supporting web and data access portals, long-running services, data analytics, data processing, and general cloud-based virtual machine capabilities. This flexible infrastructure adapts to various processing workflows, offering researchers diverse options for their computational needs.

Access and Funding

Access to NCI's computational resources is meticulously managed to ensure equitable distribution and optimal utilization. Access is granted to funding partners and researchers awarded grants under the National Computing Merit Allocation Scheme (NCMAS). This competitive allocation process prioritizes high-impact research projects.

NCI's operational funding stems from the Australian Government's NCRIS, a crucial source of support. Further funding is secured through a formal collaboration involving CSIRO, the Bureau of Meteorology, ANU, Geoscience Australia, the Australian Research Council, and several research-intensive universities and medical research institutes. This collaborative funding model emphasizes the importance of NCI's contribution to national research priorities.
