The way that your wallet is charged for the usage of SURF Research Cloud resources depends on the type of contract that backs

your wallet.

Contracts and budgets are generally issued for a specific cloud provider (SURF HPC Cloud, Azure, AWS ...). In order to see how your usage will affect your budget, look for the section on the cloud provider you use.

We now explain the financing sources that you can use within our own private cloud provider, known as SURF HPC Cloud.

SURF HPC Cloud

NWO grants

NWO Pilots (E-Infra)

Compute resources

With E-Infra grants, we do not calculate in Dollars or Euros but in "credits". One credit pays for For the usage of one core (CPU) for one hour of "wall clock time", there is a price in credits. One hour of GPU usage is charged with five creditstimes the amount of a core-hour.

Each E-Infra grant provides your project with a total of 50000 50.000 credits for compute-resources.

...

For E-Infra, the amount of granted storage is fixed. It is 2 Terabytes for one year.

NWO compute call

It is a gran that allows you to request at NWO exactly all amounts that you need in terms of compute and storage. It is meant for larger and long-lasting research when an NWO Pilot falls short.

RCCS and project-based contracts

For RCCS contracts between your institute and SURF, the billing of compute resources and storage depends on the individual contract. If your institution does not have an RCCS contract, you can make an agreement with SURF about what you need, and we will then sign a contract for your project.

Please contact your own institute or SURF customer support about these contract details.
