The SparCity project aims at creating a supercomputing framework that will provide efficient algorithms and coherent tools specifically designed for maximising the performance and energy efficiency of sparse computations on emerging HPC systems, while also opening up new usage areas for sparse computations in data analytics and deep learning. The framework enables comprehensive application characterization and modeling, performing synergistic node-level and system-level software optimizations. By creating a digital SuperTwin, the framework is also capable of evaluating existing hardware components and addressing what-if scenarios on emerging architectures and systems in a co-design perspective. To demonstrate the effectiveness, societal impact, and usability of the framework, the SparCity project will enhance the computing scale and energy efficiency of four challenging real-life applications that come from drastically different domains, namely, computational cardiology, social networks, bioinformatics and autonomous driving. By targeting this collection of challenging applications, SparCity will develop world-class, extreme scale and energy-efficient HPC technologies, and contribute to building a sustainable exascale ecosystem and increasing Europe’s competitiveness.

IntelCARM: "Boosting the roofline-based optimization guidance and performance modeling for modern CPU systems"
Principal Investigator (PI)
Intel Corporation | Intel Research Grant

As computing systems evolve towards complex multi-core designs with deep and diverse memory hierarchies, improving the performance and optimizing the execution of real-world applications become of fundamental importance. To abstract this complexity in an intuitive way, recent application analysis tools and frameworks rely on insightful modeling, e.g., Intel Advisor with Cache-aware Roofline Model. However, these approaches mainly consider the maximum architecture capabilities, which may limit their ability to accurately capture the behaviour of real-word applications. This is a gap that the work proposed in this project intends to close by focusing on research and development of existing and novel approaches for precise, insightful and application-driven performance modeling of computation and memory resources in the state-of-the-art Intel platforms. Besides significant scientific contributions, the outcomes of this project are also expected to provide Intel tools and hardware customers with direct and intuitive guidance based on investigated modeling and optimization methodologies.

EMC2 is an ARTEMIS Joint Undertaking project in the Innovation Pilot Programme "Computing platforms for embedded systems" (AIPP5). Embedded systems are the key innovation driver to improve almost all mechatronic products with cheaper and even new functionalities. They support today’s information society as inter-system communication enabler. A major industrial challenge arises from the need to face cost efficient integration of different applications with different levels of safety and security on a single computing platform in an open context. EMC2 finds solutions for dynamic adaptability in open systems, provides handling of mixed criticality applications under real-time conditions, scalability and utmost flexibility, full scale deployment and management of integrated tool chains, through the entire lifecycle. The objective of EMC2 is to establish Multi-Core technology in all relevant Embedded Systems domains. EMC2 is a project of 99 partners of embedded industry and research from 19 European countries with an effort of about 800 person years and a total budget of about 100 million Euro.

HiPerBio: "High Performance and Energy-efficient Processing of Bioinformatic Applications on Emergent Heterogeneous Systems"
Principal Investigator (PI) | HiPerBio
LISBOA-01-0145-FEDER-031901 (PTDC/CCICOM/31901/2017) | National Project (PT)

Massive publication of biological data has led to the tremendous increase in computational complexity of modern bioinformatics applications, thus urging the development of fast and accurate methods to find solutions in exponentially-growing search spaces. To tackle this challenge, this project aims at fully exploiting parallel processing opportunities of different bioinformatics applications (high order epistasis detection and phylogenetic reconstruction) for secure high performance and energy-efficient computing in emerging heterogeneous systems. For this purpose, in this project, a set of breakthrough modeling and innovative task scheduling methods are proposed to leverage the capabilities of computation, communication and memory resources by considering an extensive range of current and future heterogeneous systems: from embedded and general-purpose multi-core CPU systems, up to platforms with massively parallel accelerators, co-processors and reconfigurable devices (i.e., GPUs and FPGAs).

The goal of the NESUS Action is to establish an open European research network targeting sustainable solutions for ultrascale computing aiming at cross fertilization among HPC, large scale distributed systems, and big data management. The network will contribute to glue disparate researchers working across different areas and provide a meeting ground for researchers in these separate areas to exchange ideas, to identify synergies, and to pursue common activities in re- search topics such as sustainable software solutions (applications and system software stack), data management, energy efficiency, and resilience. Some of the most active research groups of the world in this area are members of this proposal (from 33 participating countries). This Action will increase the value of these groups at the European-level by reducing duplication of efforts and providing a more holistic view, it will promote the leadership of Europe, and it will increase their impact on science, economy, and society.
