The ESiWACE projects develop and support specific software packages concerning computing and storage aspects.
As a service to the earth system modelling community, HPC programming support for refactoring models and porting them to GPU architectures is provided via open calls.
Further, more specific calls provide support for key software components.

Refactoring and Porting

Apply for support with refactoring or porting your weather and climate code to GPUs!


Apply for support for OASIS-MCT, a coupler, allowing synchronized exchanges of coupling information between numerical codes representing different components of the climate system


Apply for support for the XIOS I/O management library for climate codes!


Get free support for the python based workflow engine and meta-scheduler!

OpenIFS programme

An easy-to-use version of the ECMWF Integrated Forecasting System model (IFS)


A modelling framework for oceanographic research, operational oceanography seasonal forecast and climate studies

Data Analysis and Visualisation

Turning large data into visuals

HPCW Benchmark

ESiWACE will extend and support the High Performance Climate and Weather (HPCW) benchmark developed in ESCAPE-2.
