Numeric Weather

Numeric Weather is a complete solution for Numerical Weather Prediction system and is a combination of:

  • high performance computing with
  • state of the art local area numeric weather prediction (NWP) models

The complete solution includes also necessary training, customization and maintenance.

Numeric Weather – software

OS platform:

  • Linux

Numerical Models:

  • COSMO – non-hydrostatic, resolution up to 2.8 km by DWD/COSMO Consortium
  • WRF – non-hydrostatic Weather Research & Forecasting Model by NCAR, NCEP, FSL, AFWA, FAA.
  • WAMS – Wave model by GKSS
  • WAVEWATCH III – Wave model by NOAA


  • Hardware scalable from off-the-shelf basic system to customized high performance cluster (HPC)
  • Latest developments in hardware allow to build an affordable NWP system by using stock parts
  • Brings the possibility to calculate your own simple NWP model

An entry 4-way system for testing purposes

  • 4 x Intel E5 2630v4 CPU, 12 cores each
  • 64 GB RAM
  • 6 x 2TB SATA disks

Professional HPC cluster for example with 72 computing nodes

  • 72 Twin Nodes (2 nodes in one enclosure)
  • Xeon E5 2630v4 / 64GB RAM per node
  • InfiniBand FDR interconnect
  • Remote management and monitoring, KVM over IP

Front-end node

  • Used as boot server and management of compute nodes
  • same configuration as compute node
  • KVM over IP
  • Remote management module


  • 144 port InfiniBand switch
  • 144 port Gigabit Ethernet switch
  • Switched rack PDU to power-cycle nodes

Storage subsystem: 1–5 storage servers

  • Each server is equipped with 24 1TB disks in RAID-6 configuration
  • Protects against failure of 2 disks at the same time
  • 2 hot-spare drives
  • Usable capacity is 20TB per server
  • InfiniBand interconnect
