High Performance Computing

High Performance Computing (HPC), also known as supercomputing, allows New Zealand researchers to tackle large, difficult problems and conduct research investigations much faster. NeSI's HPC resources, services, and support enable New Zealand researchers to greatly increase the size and speed of processing their scientific workloads, and to investigate scientific problems that were previously impossible.

Learning More / Getting Started

NeSI hosts weekly “Getting Started on NeSI” workshops for new NeSI users (or those who would like a refresh), to help you get started on the systems. These sessions are also open to researchers interested in learning more about HPC using NeSI, prior to getting a NeSI account. These introductory sessions share an overview of NeSI systems and the HPC platforms' capabilities, the available software and environment modules, and best practice and common commands for submitting, scheduling, and optimising your jobs on the system.

Sessions are delivered weekly at 1:00 PM on Wednesdays. To receive the Zoom videoconference link for these sessions, please contact NeSI Support.

If you are unable to join us on Wednesdays, please contact Support and we can investigate an alternate time for an individual on-boarding session.

Gaining Access

Evaluate our systems

Fill in our proposal form. Form submissions are reviewed weekly, require no funding and you can probably be up and running within 10 business days.

Conduct research

Fill in our proposal form. Form submissions are reviewed every two months. Investigators are required to provide evidence of scientific merit via a peer-reviewed research grant, and have experience operating an HPC facility. Past experience can be demonstrated via reference to a previous allocation on NeSI or another HPC facility. Researchers are typically submitting their first jobs within 20 working days of the form submission being reviewed.

Postgraduate study

Fill in our proposal form. Postgraduates have lower entry requirements than career researchers. They do not have to demonstrate the project's scientific merit. Experience operating an HPC facility remains highly desireable. New researchers should first carry out an evaluation of their work and needs on our systems.

Conduct commercial research & development

We welcome commercial research at NeSI. Businesses are required to provide 100% funding for their time and demonstrate experience using an HPC facility. For evaluation and testing, use the standard proposal form. Evaluation proposals can be submitted outside of any formal arrangement at any time and provide zero cost access.


See Partners and Pricing for details.

Technical Information / User Documentation

Visit our NeSI User Support Centre for more technical information and user guides for the systems. Example starting points include: 

If you can't find the technical information or documentation you need, submit a Support request and a member of our team will reply and assist.

Data Transfer and Share

Do you have large datasets that need transferred between collaborators or from an instrument to NeSI's computational environment? NeSI's national Data Transfer Platform enbables you to share your research data with collaborators around the world via a high-speed dedicated science network. Click here for more information about our Data Transfer Platform.


NeSI's Consultancy service is accessible to research groups who have a current HPC project. We can assist to streamline workflows, optimise codes, enhance I/O performance and find other ways to enable you to get the most out of the NeSI HPC Service.
