Contents

• Application templates:
  • Weather and climate:
    • RISICO - Risks of wildlands fires simulations
    • Continuum - Hydrology simulations
    • WRF GFS computation over Italy - similar to Continnum, with just the pre-processing and WRF computation on HPC
    • ADMS - Air quality
    • Agriculture - Agricultural impact models
  • Computational Fluid Dynamics:
    • OpenFOAM workflow
  • Remote visualization:
    • Xpra - Remote visualization on cloud compute instance with Xpra
    • Xpra service - Service providing remote visualization on cloud compute instance with Xpra, until the user decides to delete the workflow execution
• Examples of generic templates:
  • LEXIS template - Generic LEXIS application template with:
    • a pre-processing container executed on a Cloud Compute Instance
    • a computation performed on HPC using HEAppE
    • data transfers using LEXIS Data Transfer Infrastructure APIs
  • Cloud Computation running a public Docker container performing:
    • the transfer of a input dataset from DDI
    • a computation done by a Docker Container using these inputs
    • the transfer of result files produced by this container to DDI
  • Cloud Computation running a private Docker container archive in DDI performing:
    • the transfer of a input dataset from DDI
    • the transfer of a docker image archive from DDI
    • the docker load of this archive
    • a computation done by a Docker Container using these inputs
    • the transfer of result files produced by this container to DDI
  • Cloud Computation running a user-defined script performing:
    • the transfer of a input dataset from DDI
    • a computation done by a user-defined script
    • the transfer of result files produced by this script to DDI
  • HPC Computation using HEAppE performing:
    • the creation of a HEAppE job on a HPC cluster
    • the transfer of a input dataset from DDI to this HEAppE job
    • the submission and monitoring of this HEAppE job until it ends
    • the transfer of result files produced by this HEAppE job to DDI
  • HPC Computation with failover using HEAppE performing:
    • same as above, with the ability to store in DDI checkpoint files produced by the HEAppE during its execution, and failover to another HPC location in case of failure.
  • Service provided by a public Docker container on a Cloud instance performing:
    • the transfer of a input dataset from DDI
    • running in detached mode a Docker container, until the user decides to delete the workflow execution
  • Service provided by a private Docker container archive in DDI performing:
    • the transfer of a input dataset from DDI
    • the transfer of a docker image archive from DDI
    • running in detached mode the Docker container using this image, until the user decides to delete the workflow execution
