Costs, evictions and funding

Calculate your compute costs, learn about eviction charges and secure funding for your research.

There is a cost associated with using the Nimbus, so you will need funding to cover your computational costs.

Calculate your compute costs

Use the tool to calculate your compute costs.

Simply launch the tool, then select the and specify how many node hours you need.

Eviction charges

are available at a much lower cost than . However, Spot VM workloads can be evicted (terminated) and your unsaved data will be lost.

Your Spot VM job is more likely to get evicted if you:

Run your job on many nodes
Run jobs for long durations

And Spot VMs are only ideal for workloads that:

Use , so they can handle being evicted, and
Have a lower risk of eviction

Research Computing will cover the cost of your evicted jobs up to 6 Node Hours.

If you run a job larger than 6 Node Hours on Spot VM and it is evicted, you will be charged for the cost incurred up until your job is evicted. This charging policy is in place to ensure we stay within the centrally allocated Research Computing budget.

Secure funding to run your workloads

You can receive high performance computing (HPC) funding from your department's Research Computing Champion, or a research project PI may grant you access to use their HPC budget.

Alternatively, you can apply for a University Research Computing Accelerator Award or external grant funding. Find out more.

Manage your HPC funds

Manage your HPC funds with the Research Computing Account Management (RCAM) Portal

RCAM Portal

Use the University's to administer your HPC budget, adjust budget allocations and monitor your spending.

You need a (University VPN connection) to access the portal.

Top up your HPC budget
Research grant holders and owners of Business World (Agresso) cost codes can request to have additional funds transferred into their 'HPC budget' category.
