Dark Silicon: From Embedded to HPC Systems (Dagstuhl Seminar 16052)

Authors: Hans Michael Gerndt, Michael Glaß, Sri Parameswaran, and Barry L. Rountree

Published in: Dagstuhl Reports, Volume 6, Issue 1 (2016)

Abstract
Semiconductor industry is hitting the utilization wall and puts focus on parallel and heterogeneous many-core architectures. While continuous technological scaling enables the high integration of 100s-1000s of cores and, thus, enormous processing capabilities, the resulting power consumption per area (the power density) increases in an unsustainable way. With this density, the problem of Dark Silicon will become prevalent in future technology nodes: It will be infeasible to operate all on-chip components at full performance at the same time due to the thermal constraints (peak temperature, spatial and temporal thermal gradients etc.). However, this is not only an emerging threat for SoC and MPSoC designers, HPC faces a similar problem as well: The power supplied by the energy companies as well as the cooling capacity does not allow to run the entire machine at highest performance anymore. The goal of Dagstuhl Seminar 16052 "Dark Silicon: From Embedded to HPC Systems" was to increase the awareness of the research communities of those similarities and to work and explore common solutions based on more flexible thermal/power/resource management techniques both for runtime, design time as well as hybrid solutions.

Automatic Application Tuning for HPC Architectures (Dagstuhl Seminar 13401)

Authors: Siegfried Benkner, Franz Franchetti, Hans Michael Gerndt, and Jeffrey K. Hollingsworth

Published in: Dagstuhl Reports, Volume 3, Issue 9 (2014)

Abstract
This report documents the program and the outcomes of Dagstuhl Seminar 13401 "Automatic Application Tuning for HPC Architectures". This workshop featured a series of talks and four breakout sessions on hot topics in the are of autotuning. The field of autotuning for HPC applications is of growing interest and many research groups around the world are currently involved. However, the field is still rapidly evolving with many different approaching being taken to autotuning. This workshop provided an opportunity to discuss these many approaches, and help to unify the terminology used by different groups.

09131 Executive Summary – Service Level Agreements in Grids

Authors: Hans Michael Gerndt, Omer F. Rana, Gregor von Laszewski, and Wolfgang Ziegler

Published in: Dagstuhl Seminar Proceedings, Volume 9131, Service Level Agreements in Grids (2009)

Abstract
Grid computing allows virtual organizations to share resources across administrative domains. In its early days, Grid computing was inspired by the need for transparent access to supercomputing resources and by the idea to even couple the resources in a metacomputing environment to create even more powerful computational resources. Currently the focus is on service-oriented architectures (SOA) where a wide variety of services from multiple administrative domains can be accessed by service clients. One of the most important tasks of current Grid middleware centers on efficient resource management. Resource providers offer their resource to virtual organizations and publish detailed information about the resources. Recent efforts have also focused on exposing computational and data resources as “services” – thereby providing a single abstraction that could be applied at different levels of software deployment. Based on this information appropriate resources for Grid applications are selected, and jobs are finally submitted to these resources. Service Level Agreements (SLA) are attracting more and more attention in Grids as a means to guarantee quality of service terms for grid applications and to enable the establishment of novel business models. A wide range of research and development questions have to be addressed in this context. This covers the creation of languages for formulating SLAs that are powerful enough to express the relevant QoS terms, but can also be used to automatically manage the negotiation, execution, and monitoring of SLAs. Brokering systems are required that can select resources for job execution based on the SLA templates offered by the resource owners. Scheduling algorithms that can optimize for different goals in the context of multi-item, multi-attribute, and multi-unit optimization problems are also necessary. Flexible local resource management algorithms are required for provisioning the resources at the provider’s side to meet signed SLAs. The seminar brought together people working on SLAs in the context of grid computing mainly from computer science, but also from information systems and application areas. These researchers come from different areas and bring in a wide range of research work.
