A Parallel HIRLAM Weather Forecasting Model
Project team
Research Description
HIRLAM stands for HIgh Resolution
Limited
Area Model, and is a state-of-the-art analysis and forecast system for
numerical weather forecasts.
It is in use at several of the meteorological services (e.g. KNMI and SMHI)
participating in the HIRLAM project for their routine weather forecasting.
In the collaboration between the HIRLAM group and the HPC division in Leiden
it is investigated in which way a large-scale application like the
calculation of a numerical weather forecast has to be adapted to utilize
high performance computer systems efficiently. Also the barriers to achieve
this goal for a production code like HIRLAM are studied.
This project should indicate how a production code has to be adapted to be
able to use parallel computer systems efficiently. As a secondary result
guidelines are provided to improve automatic parallelizing compilers
from an application writer's point of view.
Collaborations
Collaboration exists with the HIRLAM-project group. This is an European
consortium of several meteorological institutes and universities in Denmark,
Finland, Ireland, Iceland, the Netherlands, Norway, and Sweden.
For this particular project we cooperate closely with
KNMI (De Bilt, the Netherlands) and
SMHI (Norrk\"oping, Sweden).
