About the position

This position is aimed at those who want to work at the intersection of information technology, research, and research methods, together with the Section for Research Services at the University of Oslo’s Center for IT (USIT). The main task of this position is to port code to accelerators and to implement new algorithms on accelerator hardware.

The Section for Research Infrastructure is located in the Department of IT in Research. USIT is responsible for the operations, development, and user support for IT solutions and services at the University of Oslo (UiO). USIT is one of Norway’s largest public IT environments with 200 employees. We work with a broad range of future oriented technologies across a large set of interesting problems. We emphasize giving employees challenging opportunities, providing the foundation for rich learning and personal development.

The division as a whole is responsible for tasks under the mandate of Uninett Sigma2, the organization for national collaboration for storage and High Performance Computing (HPC). Sigma2 is also the organization through which Norway participates in international projects on storage and computing. As such, the position has important deliveries at a national and international level, and consequently some traveling is expected.

The department collaborates with CERN in operating experiments as part of the Worldwide LHC Computing Grid (WLCG) and the Nordic Datagrid Facility (NDGF). In PRACE (Partnership for Advanced Computing in Europe) the department has responsibilities in HPC operations for the Nordic Tier-1 resources, for experimenting with new technologies for the future of HPC, and in prototyping of Exascale-ready software solutions. Similar activities are also pursued through our involvement with the European Open Science Cloud (EOSC) and the Nordic eInfrastructure Collaboration (NeIC). Locally at UiO, the division has responsibility for the Services for Sensitive Data (TSD) and its HPC cluster, Colossus. TSD is Norway’s largest special purpose eInfrastructure, primarily serving the needs of health researchers in Norway and European projects such as Tryggve2. UiO is also part og the Lumi consortium thorugh Uninett Sigma2, Lumi is a pre-exascale HPC system in the EuroHPC setting, and Lumi will be an accelerator-dominated system.
