Adaptive multi-tier intelligent data manager for Exascale

Description du projet

Un stockage adaptatif intelligent pour dynamiser le calcul haute performance

Le besoin croissant de traiter des ensembles de données extrêmement volumineux est le moteur qui accélère la transition vers le calcul à haute performance. Cependant, les hiérarchies de stockage de données plates avec un système de fichiers parallèle central se révèlent inappropriées. Les hiérarchies de stockage multi-tiers émergentes pourraient répondre aux besoins des applications à forte intensité de données, mais il leur manque actuellement des mécanismes de contrôle appropriés pour les ressources disponibles. Le projet ADMIRE, financé par l’UE, prévoit de développer un système de stockage adaptatif qui devrait permettre aux systèmes de calcul à haute performance de fournir un débit très élevé et d’augmenter la performance des applications. L’objectif consiste à améliorer considérablement le temps d’exécution des applications dans des domaines tels que les prévisions météorologiques, la télédétection et l’apprentissage profond.

Objectif

The growing need to process extremely large data sets is one of the main drivers for building exascale HPC systems today. However, the flat storage hierarchies found in classic HPC architectures no longer satisfy the performance requirements of data-processing applications. Uncoordinated file access in combination with limited bandwidth make the centralised back-end parallel file system a serious bottleneck. At the same time, emerging multi-tier storage hierarchies come with the potential to remove this barrier. But maximising performance still requires careful control to avoid congestion and balance computational with storage performance. Unfortunately, appropriate interfaces and policies for managing such an enhanced I/O stack are still lacking.

The main objective of the ADMIRE project is to establish this control by creating an active I/O stack that dynamically adjusts computation and storage requirements through intelligent global coordination, malleability of computation and I/O, and the scheduling of storage resources along all levels of the storage hierarchy. To achieve this, we will develop a software-defined framework based on the principles of scalable monitoring and control, separated control and data paths, and the orchestration of key system components and applications through embedded control points.

Our software-only solution will allow the throughput of HPC systems and the performance of individual applications to be substantially increased – and consequently energy consumption to be decreased – by taking advantage of fast and power-efficient node-local storage tiers using novel, European ad-hoc storage systems and in-transit/in-situ processing facilities. Furthermore, our enhanced I/O stack will offer quality-of-service (QoS) and resilience. An integrated and operational prototype will be validated with several use cases from various domains, including climate/weather, life sciences, physics, remote sensing, and deep learning.
