Fact sheet for HPCF

Three Cray supercomputers —Māui, Mahuika and Kupe—make up the High Performance Computing Facility.

  • Māui and Mahuika are housed at NIWA’s Wellington campus. Kupe is sited at the University of Auckland's Tamaki Data Centre.  
  • Together the three computers are capable of processing more than two thousand trillion calculations per second.
  • The HPCF contains more than 14 petabytes of high performance storage along with 200 petabytes of archive storage and all scientific data is fully backed up.
  • The facility housing Māui and Mahuika features the latest heat transfer technology cutting cooling costs by half.  
  • The facility has been specially constructed to withstand both seismic and tsunami threats.
