The Workshop on Automatic Performance Analysis (WAPA 2005, Dagstuhl Seminar 05501), held December 13-16, 2005, brought together performance researchers, developers, and practitioners with the goal
of better understanding the methods, techniques, and tools that are needed for the automation of performance
analysis for high performance computing.
From 12.12.05 to 16.12.05, the Dagstuhl Seminar 05501 ``Automatic Performance Analysis'' was held in the International Conference and Research Center (IBFI),
Schloss Dagstuhl.
During the seminar, several participants presented their current
research, and ongoing work and open problems were discussed. Abstracts of
the presentations given during the seminar as well as abstracts of
seminar results and ideas are put together in this paper. The first section
describes the seminar topics and goals in general.
Links to extended abstracts or full papers are provided, if available.
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.
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...
From 22.03. to 27.03.09, the Dagstuhl Seminar 09131 ``Service Level Agreements in Grids '' was held in Schloss Dagstuhl~--~Leibniz Center for Informatics.

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 ab...
