16 January 2024 – Munich, Germany
A Flexible, Integrated Software Stack for HPC Systems
The three EuroHPC projects DEEP-SEA, IO-SEA and RED-SEA have developed exciting European technology for use in HPC systems, targeting improvements in delivered performance and energy efficiency as well as ease of use of heterogeneous systems.
The three SEA projects are now organising a major workshop event at the end of their project period. This final workshop will present and discuss the key results of the three projects. The projects will demonstrate open source software elements and best practices that can be deployed today to benefit developers of HPC applications and operators of supercomputers alike.
The workshop will take place on-site at the Leibniz Supercomputing Centre (LRZ) in Garching / Munich on 16 January, one day before the start of the HiPEAC Conference in Munich. All HPC experts and practitioners are invited to participate.

| 9:30 – 10:00 | Registration | |
| 10:00 – 10:10 | Welcome: Intro to the day | Hans-Christian Hoppe (JSC), Sai Narasimhamurthy (Partec), Jesús Escudero-Sahuquillo (UCLM), Pedro J. García (UCLM) |
| 10:10 – 11:00 | The SEA project family This talk will give a short introduction to the 3 SEA projects and how they link together. | Hans-Christian Hoppe (JSC), Sai Narasimhamurthy (Partec), Jesús Escudero-Sahuquillo (UCLM), Pedro J. García (UCLM) |
| 11:00 – 11:45 | DASI: a user centric data access and storage interface DASI, a Data Access and Storage Interface, enables users to manage data using domain specific and scientifically meaningful metadata keys, and separates data management from the underlying backend storage technology through abstraction. Based on the FDB object store developed and in operational use at ECMWF, we will describe its concept and how it can be easily adopted by any domain as a data management solution. | Jenny Wong (ECMWF) |
| 11:45 – 12:30 | The VEF traces framework: collecting traffic traces from modern, highly-demanding applications This framework is a set of open-source tools that allows to generate traces from applications demanding high network performance. We will describe the different tools, and how the resulting traces can be used to characterise the traffic in modern systems supported by high-performance networks, as well as how these traces can be used to feed interconnection network simulators. | Jesús Escudero-Sahuquillo and Pedro J. García (UCLM) |
| 12:30 – 13:30 | Lunch | |
| 13:30 – 14:15 | Optimisation Cycles for Modular Supercomputing and Energy Efficiency Optimisation cycles encapsulate advanced performance analysis and tuning tools to guide users through the steps required to obtain a certain analysis or optimisation result. We introduce two of these cycles: one for determining on which modules (such as CPU or GPU-based) to best run an application, and one to optimise the energy efficiency of CPU workloads at runtime. | Alexander Geiß (TUD) and Mathieu Stoffel (Eviden) |
| 14:15 – 15:00 | Continuous Integration of the HPC SW Stack Continuous integration is common practice in many fields of computing. We introduce its use for guaranteeing the consistency of the full HPC stack, covering applications, programming models, libraries, and system software, and provide examples on how to use open source SW to achieve this. | Manoel Roemer (FZJ) and Sonja Happ (Partec) |
| 15:00 – 16:00 | Coffee break // Tour of LRZ Computing Center | |
| 16:00 – 16:45 | The Smart Burst Buffer: An example of an ephemeral service and its connection to the long term storage SBB, as an example of ephemeral IO service, provides workflows with isolation from other applications, buffering and cache, improving time to solution. As an ephemeral service, it relies upon a long term storage service for which the Hestia API has been developed as an abstraction of a tiered storage infrastructure. We will introduce in this talk the IO-SEA run time architecture and the benefits workflows can get of it. | Philippe Couvée (Eviden) and James Grogan (ICHEC) |
| 16:45 – 17:00 | Joint SEA Demo | Hans-Christian Hoppe (JSC), Philippe Couvée (Eviden), Grégoire Pichon (Eviden) |
| 17:00 – 17:15 | Wrap up and Conclusion | Hans-Christian Hoppe (JSC), Sai Narasimhamurthy (Partec), Jesús Escudero-Sahuquillo (UCLM), Pedro J. García (UCLM) |
