ODISSEI Secure Supercomputer

In the ODISSEI Secure Supercomputer (OSSC), researchers can perform analyses of highly-sensitive data – such as CBS Microdata – in SURF’s high performance computing environment Snellius. The ODISSEI Secure Supercomputer (OSSC) consists of an enclave of Statistics Netherlands (CBS) within the domain of SURF. This virtual IT environment offers a high performance computing environment that meets the requirements of Statistics Netherlands (CBS) in legal, technical and security requirements.

The OSSC is designed to service and facilitate a wide range of applications that are impossible or difficult to execute in the regular CBS-RA environment, including the need for additional memory, computing and specialised hardware (Graphical Processing Units (GPUs) which excel in parallel processing of data).

  • Projects requiring larger working memory for large amounts of pre-processing
  • Project applying population scale analysis (large N)
  • Projects that are computationally intensive and apply complex analysis such as network analysis, Agent-Based Modelling, or Neural Networks
  • Projects that include datasets that too large to upload to CBS 

The environment has been in production since 2020 and SURF is constantly working on improving the user experience and maintaining the strictest security levels of the facility.

Using OSSC

The ODISSEI Secure Supercomputer is available for use by all researchers working at a SURF member organisation. Researchers interested in working with the OSSC should contact the CBS project manager about the possibilities and send an inquiry to the SURF Help Desk about using OSSC as a service.

If you have questions about using the OSSC, please contact our Scientific Manager, Kasia Karpinska.

Projects using OSSC

The OSSC has been used by many projects utilising different facets of the facility.
