The Hackathon will focus on enabling Verification, Validation and Uncertainty Quantification (VVUQ) for HPC simulations using the SEAVEA toolkit (SEAVEAtk). Any HPC application researcher is invited to join, irrespective of their source domain. During the event, participants will learn about the SEAVEA toolkit, and RADICAL Cybertools in particular. They will engage in hands-on learning by interacting with the SEAVEAtk experts, who will help them in applying their choice of SEAVEAtk tools on their own codes and applications. Existing SEAVEAtk users are also welcome, as the team will offer support to add more rigorous VVUQ to their applications.

About RADICAL Cybertools:

RADICAL-Cybertools (RCT) are software building blocks to enable execution of scientific workflows on high performance computing (HPC) platforms at unprecedented scale. Two of the most commonly used RCT are RADICAL-Pilot (RP) and RADICAL-EnsembleToolkit (EnTK). RP is a pilot-enabled runtime system that allows users to concurrently execute up to 10^4 heterogeneous tasks on up to 10^5 heterogeneous resources. RP manages concurrent and sequential execution of single/multi core/GPU/node non/MPI tasks on one or more HPC platforms. Tasks can be stand-alone executables or Python functions. EnTK is a workflow engine specifically designed to support the coding and execution of scientific workflows specified as a set of pipelines. Each independent pipeline contains a user-defined sequence of stages, each containing a user-defined number of tasks. EnTK utilizes RP to acquire and manage HPC resources, and place and launch tasks on those resources. Along with Flux and Parsl, RCT is also part of ExaWorks, a DOE ExaScale Computing Project,  that integrates independent middleware to enable the execution of scientific workflows on HPC. Within ExaWorks, RCT is part of the Software Development Kit (SDK), enabling the continuous integration and testing of both RP and EnTK on diverse HPC platforms. RCT supports innovation in climate science, drug discovery, material engineering, computational biology and particle physics, consuming millions of core hours on the largest HPC machines available world-wide.

About SEAVEAtk: 

The SEAVEA toolkit provides a variety range of tools to:

• create VVUQ procedures (EasyVVUQ),
• to facilitate the creation of surrogate models for multiscale simulations (EasySurrogate),
• to automate the complex workflows emerging from these procedures using HPC resources (FabSim3),
• to enable the efficient execution of large numbers of jobs on computational resources (QCG Pilot Job Manager and RADICAL Cybertools),
• to make creating coupled multiscale simulations easy, and to then enable efficient Uncertainty Quantification of such models using advanced semi-intrusive algorithms (MUSCLE3),
• to perform surrogate modelling using Gaussian Processes (MOGP).
