Milner

Milner was a CRAY XC30 system for neuroinformatics research.

Milner system for neuroinformatics

PDC operated Milner on behalf of a consortium of researchers from KTH, the Karolinska Institute and the International Neuroinformatics Coordination Facility (INCF). The system was installed at PDC in February 2014. After being decommissioned at the end of March 2017, it was used as a test and development system (TDS).

The system was named in honour of the British neuropsychologist Brenda Milner .
