Third Nesus Action Workshop


NESUS 2016

IICT-BAS, Sofia, Bulgaria. October, 6-7, 2016


The ever-increasing data and processing requirements of applications from various domains are constantly pushing for dramatic increases in computational and storage capabilities. Today, we have reached a point where computer systems’ growth cannot be addressed anymore in an incremental way, due to the huge challenges lying ahead, in particular scalability, energy barrier, data management, programmability, and reliability.

Ultrascale computing systems (UCS) are envisioned as a large-scale complex system joining parallel and distributed computing systems, maybe located at multiple sites, that cooperate to provide solutions to the users. As a growth of two or three orders of magnitude of today’s computing systems is expected, including systems with unprecedented amounts of heterogeneous hardware, lines of source code, numbers of users, and volumes of data, sustainability is critical to ensure the feasibility of those systems. Due to those needs, currently there is an emerging cross-domain interaction between high-performance in clouds or the adoption of distributed programming paradigms, such as Map-Reduce, in scientific applications, the cooperation between HPC and distributed system communities still poses many challenges towards building the ultrascale systems of the future. Especially in unifying the services to deploy sustainable applications portable to HPC systems, multi-clouds, data centers, and big data.

NESUS 2016 workshop focuses on the software side, aiming at bringing together researchers from academia and industry interested in the design, implementation, and evaluation of services and system software mechanisms to improve sustainability in ultrascale computing systems with a holistic approach.
