Background
----------

As the word "UnConventional" in the title suggests, the workshop focuses
on hardware or platforms used for HPC, which were not intended for HPC
in the first place. Reasons could be raw computing power, good
performance per watt, or low cost in general. To address this
unconventional hardware, often, new programming approaches and
paradigms are required to make best use of it. Thus, a second focus of
the workshop is on innovative new programming models for unconventional
hardware and how to best combine its computing power with more
conventional systems. To this end, UCHPC tries to capture solutions for
HPC which are unconventional today but could become conventional and
significant tomorrow.

For example, the computing power of platforms for games recently raised
rapidly. This motivated the use of GPUs for computing (GPGPU), or even
building computational grids from game consoles. The trend of
integrating GPUs on processor chips seem to be very beneficial for use
of both parts for HPC. Other examples for "unconventional" hardware are
embedded, low-power processors, upcoming many-core architectures, FPGAs
or DSPs. Thus, interesting devices for research in unconventional HPC
are not only standard server or desktop systems, but also relative
cheap devices due to being mass market products, such as smartphones,
netbooks, tablets or small NAS servers. Especially smartphones seem to
become more performance hungry every day. Only imagination sets the
limit for use of the mentioned devices for HPC.


Topics
------

The goal of the workshop is to present latest research in how hardware
and software (yet) unconventional for HPC is or can be used to reach
goals such as best performance per watt. UCHPC also covers 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), using GPUs embedded on processor dies (as found in AMD
Fusion/APUs, NVidia Denver, Intel Ivy Bridge), Intel's MIC and SCC,
low power/embedded processors (including DSPs, Adapteva Epiphany),
FPGAs (e.g. Convey), Tilera's tile-based many-core processors, IBM
Cell BE, accelerators, visualization cards, etc.
* Cluster/Grid solutions using unconventional hardware, e.g. clusters of
game consoles, nodes using GPUs, Low Power/Embedded Processors,
MPSoCs, new many-cores from Intel and/or ARM designs, Mac
Minis/AppleTVs, FPGAs etc.
* Heterogeneous computing on hybrid platforms
* Work on and use of new programming models and paradigms needed to
support unconventional hardware, and hybrid/hierarchical combinations
with more conventional systems. Examples are OpenACC, OpenCL, Cilk+,
and task-based approaches for heterogeneous systems
* 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 *ten* single-spaced, single-column
pages using LNCS proceedings style.

Submission implies that at least one author will register for the
workshops at Euro-Par 2012 and present the paper in the workshop
session, if accepted.
Upload your submission to our submission server in PDF format:

http://www.easychair.org/conferences/?conf=uchpc12

It must not be simultaneously submitted to the main conference or any
other publication outlet.

For the workshop, we will prepare handouts with the revised papers.
These will be published after the conference in the workshop
proceedings of Euro-Par 2012, part of the LNCS series of Springer.
