ABSTRACT High Performance Computing has been extremely successful by focusing on how best to support software developers that have the technical skills required to design highly parallel algorithms, to optimize data partitioning and load balancing, to minimize communications and synchronization, and to do all of the other things necessary to achieve the highest possible performance on large-scale dedicated clusters and supercomputers with CPUs, GPUs, advanced networking, and highly parallel file systems. In HPC, where choices have to be made between, for example, high performance and fault tolerance, the tendency has almost always been to focus on the former. Big Data, AI and Cloud Computing have also been extremely successful in recent years by focusing on exactly the opposite community, those software developers who do not have the technical skills, or motivation, required for HPC. In Big Data, AI and Cloud Computing, many/most of the key design decisions regarding parallelization, data partitioning, load balancing, communications, synchronization, redundancy and fault tolerance are automated, and the key objective is to enable developers to produce applications with a minimum of effort, applications that will typically be run on low-cost pools of commodity cloud hardware resources, that will often be virtualized or based on containers. In this talk, I will describe some of the challenges in bringing high performance to big data, AI and cloud computing, and describe some new approaches to this problem. As AI moves to the center of computing, and "AI-as-a-Service" becomes a major new business opportunity, this area will become more and more important. If HPC also moves to a new era in which cost-effective "cloudonomics" matters more, then it will become important there too.

Walker Cardiff School of Computer Science and Informatics ABSTRACT Efficient access to hierarchical memory is essential in achieving good performance in both sequential and parallel applications. This presentation will consider the interplay of application design, the expression of parallelism, and data movement across hierarchical memory. The talk will include a brief survey of parallel programming paradigms and algorithms, and will discuss how these might change in the era of exascale computing. Block and tile algorithms will be described as techniques for improving memory performance, and work on the use of space-filling curves to improve locality of reference will be presented.

Messina Argonne National Laboratory and ALD Exascale Project Director Illinois, USA ABSTRACT The U.S. Department of Energy established in 2016 the Exascale Computing Project (ECP) -- a joint project of the DOE Office of Science (DOE-SC) and the DOE National Nuclear Security Administration (NNSA) -- that will result in a capable exascale ecosystem and prepare mission critical scientific and engineering applications to take advantage of that ecosystem. This presentation will describe the goals of the ECP initiative, its plans for achieving them, and its current status, with special emphasis on the challenges to be overcome. SPEAKER BIOGRAPHY ![]() From 1987-2002, Dr. Messina served as founding Director of California Institute of Technology's (Caltech) Center for Advanced Computing Research, as Assistant Vice President for Scientific Computing, and as Faculty Associate for Scientific Computing, Caltech. During a leave from Caltech in 1999-2000, he led the DOE-NNSA Accelerated Strategic Computing Initiative. In his first association with Argonne from 1973-1987, he held a number of positions in the Applied Mathematics Division and was the founding Director of the Mathematics and Computer Science Division. ______________________________________________________________________ HPCS Plenary Talk: Research and Education Networks as an Enabler for Scientific Computing: The GARR Vision Federico Ruggieri Director of Research at the National Institute for Nuclear and Particle Physics (INFN) and Director of GARR, the Italian Research & Education Network, Rome, Italy ABSTRACT In the last few decades, Moore’s law and the uptake of fibre-optics have changed the way science is done. Nowadays, research groups distributed worldwide are exploiting high capacity networks and unprecedented computing power to process large amounts of data which were simply beyond our possibilities only a few years ago. Problems too complex to be tackled are now approachable, and if your data centre is still not enough, high-capacity networks can be exploited to extend it at the geographical level. In this talk, the role of National and international Research and Education Networks is highlighted, also thanks to success stories from different scientific domains, from HEP to bioinformatics to culture, and a vision for the future is sketched.
