Enabling multi-node MPI parallelisation of the LISFLOOD flood inundation model

Wednesday 4th December 2019 15:00

Arno Proeme, EPCC

The availability of higher-resolution topographic datasets covering greater spatial domains has soared in recent years, pushing the limits of computational resources beyond those typically found in regional HPC services. In addition, many countries that are subject to large-scale flooding each year do not have access to real-time flood forecasting software. This webinar describes how HAIL-CAESAR, a geosciences code that implements the LISFLOOD flood inundation model, was ported to make use of LibGeoDecomp - a C++ stencil code HPC library - to enable multi-node parallelism. Whilst currently single inundation scenarios can take multiple days to run using standard hydrological modelling software, this project paves the way for ensemble runs that can be initiated on the basis of a 24 or 48 hour rainfall forecast and complete within shorter timescales, which should ultimately have major implications for flood warnings in developing countries.

PRACE Preparatory Access Call

PRACE (Partnership for Advanced Computing in Europe) is a Research Infrastructure that allows researchers from across Europe to apply for time on high-performance computers from a series of hosting nations via a central peer review process.

Preparatory access is intended for testing and developing codes in order to prepare applications for PRACE Tier-0 project access. In particular, we would like to draw your attention to the Preparatory Access Type C and Type D which includes code development with support from PRACE experts. Type C provides direct access to a Tier-0 system. Type D offers users to start the optimisation work on a PRACE Tier-1 national system to finally reach PRACE Tier-0 system scalability.

Further information are given on the PRACE web page

The Preparatory Access Call is a rolling call, researchers can apply for access all year. There are no closing dates, proposals for Type C and Type D will be reviewed every third month.

The next cut-off date is December 2nd, 2019.

All interested scientists, whose projects fit the criteria of the PRACE call, are invited to submit their projects. The criteria for the PRACE Calls as well as complete information on the PRACE machines, how to apply and on the PRACE peer review process can be found on the website mentioned above.
