The slides for the talks are now available. See the program section below.

Due to several requests, we have extended the submission deadline by one week. The new deadline is June 21th, 2010.

Background

As the computing power of various platforms intended for games is increasing rapidly, they attract the interest of professionals in the HPC community. As an example, the modern graphics processing units (GPU) are often used for HPC in the so called field "General-Purpose computing on GPU's" (GPGPU). Another example is the Playstation3 (PS3) that has a multicore architecture that lends itself for HPC. These platforms are not conventional HPC platforms, nonetheless they are used for HPC purposes and even clusters of such computing resources are being built with great success. Both the raw computing power and the relatively low cost compared to conventional HPC resources make them very interesting. The aim of this workshop is to focus on such unconventional resources for HPC. Only imagination sets the limit for what this kind of devices can be used for in HPC, also by forming clusters.

The word "UnConventional" in the workshop title emphasizes that the focus is on hardware or platforms used for HPC, which were not intended for HPC in the first place. So, in some sense we try to capture things in this workshop that are being done in an unconventional way today but perhaps will be conventional tomorrow. That is why the C in UnConventional is in capital letters.


Topics

The goal of the session is to present latest research in how hardware and software (yet) unconventional for HPC is/can be used to reach given goals such as best performance/watt, with according programming models, compiler techniques and tools. Thus, suggested topics for papers include, but are not limited to the following:
  • Innovative use of hardware and software unconventional for HPC
  • HPC applications or visualizations in connection with HPC on GPUs (GPGPU), IBM Cell, Low Power Processors, FPGAs, Visualization cards etc.
  • Cluster/Grid solutions using unconventional hardware, e.g. clusters of PS3s, GPUs, Low Power Processors, MPSoCs, Mac Minis, FPGAs etc.
  • Performance and scalability studies in HPC using unconventional hardware
  • Reconfigurable Computing for HPC
  • Performance modeling, analysis and tools for HPC with unconventional hardware
  • New or adapted/extended (parallel) programming models for HPC with unconventional hardware

Paper Submission, Registration, and Publication

Workshop papers should not exceed eight single-spaced, single-column pages. As this is a workshop on a fast evolving topic, we encourage you to enhance your contribution with newest measurements even after the acceptance decision, but keep the total page limit in mind. Submission implies that at least one author will register for the workshops at Euro-Par 2010 and present the paper in the workshop session, if accepted.

Submissions should be sent to Anders Hast in PDF format, and must not be simultaneously submitted to the main conference or any other publication outlet.

For the workshop, we will prepare handouts with the final papers. These also will be published after the conference in the workshop proceedings of Euro-Par 2010, part of the LNCS series of Springer.


Important Dates

June 21th: Extended Submission deadline
July 19th: Notification of acceptance
Aug 23th: Final papers due
Aug 31th - Sep 3rd: Conference with workshops
Oct 2nd: Final review comments
Oct 16th: Camera ready papers
