ODISSEI Secure Supercomputer

In the ODISSEI Secure Supercomputer (OSSC), researchers can analyse their data linked to highly-sensitive data – such as CBS Microdata – in SURFsara’s high performance computing environment Cartesius. The ODISSEI Secure Supercomputer is currently being scaled up and it is expected to open to the wider research community before the summer of 2020.

In June 2018, Statistics Netherlands and SURFsara completed a successful Proof of Concept (PoC) of the ODISSEI Secure Supercomputer. The ODISSEI Secure Supercomputer consists of an enclave of Statistics Netherlands within the domain of SURFsara. In this virtual IT environment, researchers can analyse linked data in a high performance computing environment that meets the requirements of Statistics Netherlands in legal, technical and security requirements. This way, confidential information can be brought safely into the environment to be analysed with Cartesius, SURFsara’s high-performance computer.

The Proof of Concept investigated whether safe links between CBS microdata and the very large genetic dataset of the Dutch Twin Register (NTR), which is stored at SURFsara, were possible within OSSC. This linkage has been successfully established.

The PoC was then followed up by a pilot consisting of three research projects, that were carried out by TU Delft (with CBS data and a GIS component in particular), CBS (complexity in social networks based on CBS data) and VU University’s Twin Register(linking genetics to register data, using DNA profiles already included in SURFsara). These projects demonstrated the extraordinary possibilities of the OSSC.
