Background
----------

Recent issues with the power consumption of conventional HPC hardware
results in both new interest in accelerator hardware and in usage of
mass-market hardware originally not designed for HPC. The most prominent
examples are GPUs, but FPGAs, DSPs and embedded designs are also possible
candidates to provide higher power efficiency, as they are used in
energy-restriced environments, such as smartphones or tablets. The
so-called "dark silicon" forecast, i.e. not all transistors may be
active at the same time, may lead to even more specialized hardware in
future mass-market products. Exploiting this hardware for HPC can be a
worthwhile challenge.

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. A second focus of
the workshop is on innovative, (yet) unconventional new programming
models.

To this end, UCHPC tries to capture solutions for HPC which are
unconventional today but could become conventional and significant tomorrow,
and thus provide a glimpse into the eventual future of HPC.


Topics
------

The goal of this workshop is to present research exploring currently
unconventional techniques for HPC and their benefits. 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,
Processing in Memory (PIM), accelerators, 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/modified or unconventional programming models for HPC, including
e.g. PGAS or task-based concepts
* Big data and/or deep learning using unconventional HPC hardware or
software


Best Paper Award
----------------

As last year, there will be a best paper award. For the winner, we have
a special hardware price.



Paper Submission, Registration, and Publication
-----------------------------------------------

Workshop papers must not exceed 12 single-spaced, single-column pages
in LNCS proceedings style. Submission implies that at least one author
will register for the workshops at Euro-Par 2015 and present the paper
in the workshop session, if accepted.
Upload your PDF to the Euro-Par 2014 Workshop submission server, track
"UCHPC - UnConventional High Performance Computing" at

https://www.easychair.org/conferences/?conf=europar2015ws

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 2014, part of the LNCS series of Springer.
