High performance computing and data analytics

 

Using NeSI’s specialised platform of High Performance Computing (HPC) resources and data analytics services, New Zealand researchers are able to investigate large, unique, or complex projects more easily, quickly, and accurately.

 

What's Available

Using NeSI's HPC platform, you can:

  • access high-capacity CPUs, GPUs and high memory nodes 

  • work interactively using Jupyter Notebooks, containers, and virtual lab environments

  • bring your own code or access our extensive software library -- already built and compiled, ready for you to use 

  • scale your code and expand your projects
     

NeSI provides tools and services to help you get your data onto the HPC platform, store it close to the compute, process and analyse your datasets, visualise the results, and share it with colleagues. 

The platform is powered by Mahuika and Māui, designed as fit-for-purpose systems to meet your research needs. For more details on their components and capabilities, visit our User Support Centre.

Is it for me?

NeSI delivers tools that respond to researcher's evolving needs, whether it's investigating climate change, human and taonga species genomics, innovations in materials surfaces and structures, seismic modelling, or national responses to a pandemic. 

We also strive to support FAIR (Findable, Accessible, Interoperable and Reproducible) and CARE (Collective Benefit, Authority to Control, Responsibility, Ethics) principles in data and research software. 

With a NeSI account, you can:

  • Evaluate our systems
    Researchers new to NeSI are encouraged to test the suitability of a NeSI cluster for your proposed work and determine the rate of core hour usage your project is likely to need on an ongoing basis.

  • Conduct research
    We support a range of research programmes funded by peer-reviewed, contestable grants at an institutional, regional or national level. Researchers use NeSI computing and data science resources and expertise to tackle large, complex or data-intensive projects.

  • Advance postgraduate study
    With many research communities bringing HPC into their work routines and workflows, we recognise a growing need for resources that support a research degree. Projects do not need to be funded by a peer-reviewed, contestable grant in order to be considered for a Postgraduate allocation, but students must be affiliated with a New Zealand institution.

  • Support commercial research & development
    Through subscription contracts, private industry and commercial organisations can tap into NeSI's high-performing tools and user-focused support to power data-centric and data-intensive research.
