Temperature-aware thread mapping strategies are key for providing dependability in such systems. These strategies rely on measuring the temperature distribution and redicting the thermal behavior of the system when there are changes to the hardware and software running on the FPGA. While there are a number of tools that use thermal models to predict temperature distributions at design time, these tools lack the flexibility to autonomously adjust to changing FPGA configurations. To address this problem we propose a temperature-aware system that empowers FPGA-based reconfigurable multi-cores to autonomously predict the on-chip temperature distribution for pro-active thread remapping. Our system obtains temperature measurements through a self-calibrating grid of sensors and uses area constrained heat-generating circuits in order to generate spatial and temporal temperature gradients. The generated temperature variations are then used to learn the free parameters of the system's thermal model. The system thus acquires an understanding of its own thermal characteristics. We implemented an FPGA system containing a net of 144 temperature sensors on a Xilinx Virtex-6 LX240T FPGA that is aware of its thermal model. Finally, we show that the temperature predictions vary less than 0.72 degree C on average compared to the measured temperature distributions at run-time.}}, author = {{Happe, Markus and Agne, Andreas and Plessl, Christian}}, booktitle = {{Proceedings of the 2011 International Conference on Reconfigurable Computing and FPGAs (ReConFig)}}, pages = {{55--60}}, publisher = {{IEEE}}, title = {{{Measuring and Predicting Temperature Distributions on FPGAs at Run-Time}}}, doi = {{10.1109/ReConFig.2011.59}}, year = {{2011}}, } @inproceedings{2205, author = {{Birkenheuer, Georg and Blunk, Dirk and Breuers, Sebastian and Brinkmann, André and Fels, Gregor and Gesing, Sandra and Grunzke, Richard and Herres-Pawlis, Sonja and Kohlbacher, Oliver and Krüger, Jens and Lang, Ulrich and Packschies, Lars and Müller-Pfefferkorn, Ralph and Schäfer, Patrick and Schuster, Johannes and Steinke, Thomas and Warzecha, Klaus-Dieter and Wewior, Martin}}, booktitle = {{Proc. of Grid Workflow Workshop (GWW)}}, title = {{{MoSGrid: Progress of Workflow driven Chemical Simulations}}}, volume = {{829}}, year = {{2011}}, } @inproceedings{2204, author = {{Graf, Tobias and Lorenz, Ulf and Platzner, Marco and Schaefers, Lars}}, booktitle = {{Proc.

Virtualization enables the consolidation of virtual machines as well as the migration of them to other hosts during runtime. Each provider has its own strategy to efficiently operate a data center. We present a rule based mapping algorithm for VMs, which is able to automatically adapt the mapping between VMs and physical hosts. It offers an interface where policies can be defined and combined in a generic way. The algorithm performs the initial mapping at request time as well as a remapping during runtime. It deals with policy and infrastructure changes. We extended the open source IaaS solution Eucalyptus and we evaluated it with typical policies: maximizing the compute performance and VM locality to achieve a high performance and minimizing energy consumption. The evaluation was done on state-of-the-art servers in our own data center and by simulations using a workload of the Parallel Workload Archive. The results show that our algorithm performs well in dynamic data centers environments.}}, author = {{Kleineweber, Christoph and Keller, Axel and Niehörster, Oliver and Brinkmann, André}}, booktitle = {{Proc.
