Descrizione del progetto
Ottimizzare tutti i livelli di software per mirare all’eccellenza nel calcolo su esascala europeo
Il calcolo su esascala consente di effettuare simulazioni di una quantità praticamente illimitata di fenomeni, caratterizzati da dimensioni e complessità senza precedenti. Le architetture sottostanti e le capacità hardware stanno progredendo velocemente, ma anche le difficoltà sono molteplici, in particolare per quanto riguarda l’eterogeneità dell’hardware, in cui è necessario orchestrare le capacità di calcolo, memoria e archiviazione per garantire l’efficienza energetica e la sostenibilità con lo sguardo rivolto ai futuri sviluppi e condizioni. Il progetto DEEP-SEA, finanziato dall’UE, si basa su pacchetti software convalidati per creare un ambiente open-source che supporti in modo ottimale i supercomputer eterogenei e modulari, il tutto sotto la guida della co-progettazione con applicazioni provenienti da sette campi scientifici ad alto impatto. L’adattamento di tutti i livelli del parco software apporterà benefici agli innovatori e alle economie dell’UE.
Obiettivo
DEEP-SEA (“DEEP – Software for Exascale Architectures”) will deliver the programming environment for future European exascale systems, adapting all levels of the software (SW) stack – including low-level drivers, computation and communication libraries, resource management, and programming abstractions with associated runtime systems and tools – to support highly heterogeneous compute and memory configurations and to allow code optimisation across existing and future architectures and systems
At node-level the European Processor Initiative (EPI) will integrate general purpose CPUs and accelerators within the package and combine DDR and HBM memories. Consequently, DEEP-SEA will implement data placement policies for deep memory hierarchies, improving application performance on future EPI-based platforms. At system-level, CPUs and accelerators (e.g. various EPI chip configurations, or GPUs) are efficiently integrated following the Modular Supercomputer Architecture (MSA). The DEEP-SEA SW stack will enable dynamic resource allocation, application malleability, programming composability, and include tools to map applications to the MSA. Result is a SW environment enabling applications to run on the best suited hardware, in a scalable, and energy efficient manner.
Targeting a high Technology Readiness Level (TRL), the project builds upon SW developments from previous EU-projects and international open source packages widely used in the HPC community, extending them with focus on compute and memory heterogeneity. This enables close collaborations within the HPC community and Centres of Excellence (CoEs). The DEEP-SEA SW elements will be extended in a collaborative co-design approach with EU-applications, considering relations and dependencies between the various levels of the stack. Therefore, ambitious and highly-relevant EU-applications will drive the co-design, evaluate the DEEP-SEA software stack, and demonstrate its benefits for users of European compute centres.
