Power-Bounded HPC Performance Optimization (Dagstuhl Perspectives Workshop 15342)

Authors: Dieter Kranzlmüller and Barry L. Rountree

Published in: Dagstuhl Reports, Volume 5, Issue 8 (2016)

Abstract
This report documents the program and the outcomes of Dagstuhl Perspectives Workshop 15342 "Power-Bounded HPC Performance Optimization". The workshop consists of two parts. In part one, our international panel of experts in facilities, schedulers, runtime systems, operating systems, processor architectures and applications provided thought-provoking and details insights into open problems in each of their fields with respect to the workshop topic. These problems must be resolved in order to achieve a useful power-constrainted exascale system, which operates at the highest performance within a given power bound. In part two, the participants split up in three groups, trying to address certain specific subtopics as identified during the expert plenaries. These subtopics have been discussed in more detail, followed by plenary sessions to compare and synthesize the findings into an overall picture. As a result, the workshop identified three major problems, which need to be solved on the way to power-bounded HPC performance optimization.

Co-Design of Systems and Applications for Exascale (Dagstuhl Perspectives Workshop 12212)

Authors: Arndt Bode, Adolfy Hoisie, Dieter Kranzlmüller, Wolfgang E. Nagel, and Christian Straube

Published in: Dagstuhl Manifestos, Volume 4, Issue 1 (2014)

Abstract
The Dagstuhl Perspectives Workshop 12212 on "Co-Design of Systems and Applications for Exascale" is reaching into the future, where exascale systems with their capabilities provide new possibilities and challenges. The goal of the workshop has been to identify concrete barriers and obstacles, and to discuss ideas on how to overcome them. It is a common agreement that co-design across all layers, algorithms, applications, programming models, run-time systems, architectures, and infrastructures, will be required. The discussion between the experts identified a series of requirements on exascale co-design efforts, as well as concrete recommendations and open questions for future research.

Co-Design of Systems and Applications for Exascale (Dagstuhl Perspectives Worksop 12212)

Authors: Arndt Bode, Adolfy Hoisie, Dieter Kranzlmüller, and Wolfgang E. Nagel

Published in: Dagstuhl Reports, Volume 2, Issue 5 (2012)

Abstract
With more and more machines achieving petascale capabilities, the focus is shifting towards the next big barrier, exascale computing and its possibilities and challenges. There is a common agreement that using machines on this level will definitively require co-design of systems and applications, and corresponding actions on different levels of software, hardware, and the infrastructure. Defining the vision of exascale computing for the community as providing capabilities on levels of performance at extreme scales, and identifying the role and mission of the involved experts from computer science has laid the basis for further discussions. By reflecting on the current state of petascale machines and technologies and identifying known bottlenecks and pitfalls looming ahead, this workshop derived the concrete barriers on the road towards exascale and presented some ideas on how to overcome them, as well as raising open issues to be addressed in future leading-edge research on this topic.
