Welcome to Local PTHA WaaS documentation
Here is the documentation concerning the local Probabilistic Tsunami Hazard Analysis (PTHA) Workflow as a Service (WaaS).
The workflow aims at computing PTHA at a local scale for a given target site, starting from a regional hazard model, presently NEAMTHM18, that is the long-term hazard model for the NEAM region (North-East Atlantic, Mediterranean and connected seas). One target site is allowed for the moment, future upgrades will allow to process more than one.
The execution, graphically represented by a block diagram, is subdivided into 7 sequential steps, which are briefly described here .
The tsunami simulations are carried out exploiting the numerical GPU code Tsunami-HySEA. The present version requires the entire execution of the workflow on the same HPC cluster equipped with GPUs; future versions will allow to send the simulations to a remote cluster (equipped with GPUs), while executing all the other steps on a local cluster.
Info
Some background details about local PTHA can be found here.
Warning
Presently, the use of the following clusters is implemented:
- mercalli @INGV (job manager: PBS)
- leonardo @CINECA (job manager: SLURM)
More clusters could be added in the future.
