CALL FOR PAPERS
Workshop on GPU Computing
Held in conjunction with PPAM 2011 -- 9th International Conference on
Parallel Processing and Applied Mathematics
September 11-14, 2011
Torun, Poland

Overview:
---------
GPU programming is now a much richer environment that it used to be a
few years ago. On top of the two major programming languages, CUDA and
OpenCL, libraries (e.g., cufft) and high level interfaces (e.g., thrust)
have been developed that allow a fast access to the computing power of GPUs
without detailed knowledge or programming of GPU hardware.

Annotation-based programming models (e.g., PGI Accelerator), GPU plug-ins
for existing mathematical software (e.g., Jacket in Matlab), GPU script
languages (e.g., PyOpenCL), and new data parallel languages (e.g.,
Copperhead) bring GPU programming to a new level.

A major decision for libraries and high level programming tools is the
positioning within the triangle of performance, coding comfort and
specialization. The spectrum ranges from high performance building
blocks for common numeric or discrete transformations, to application
domain specific libraries facilitating the solution of a certain class
of problems, to general high level abstractions increasing the
programmer's productivity.

By sharing the experiences of utilizing programming abstractions we hope
that the participants of the workshop will gain a better understanding
which tools are good for which type of problem and which trade-offs
between performance, coding comfort and specialization are available.

A major criticism of programming abstractions is that they look great on
small examples but fail on practical problems. Therefore, this workshop
invites in particular submission that deal with practical applications
that have successfully employed GPU libraries or high level programming
tools. The focus may lie both on the development of the libraries or
utilization of existing tools. Workshop topics include, but are not
limited to:

- GPU applications coded with high level programming tools
- GPU library development and application
- Comparison of different programming abstractions on the same/similar
applications
- Comparison of the same/similar programming abstractions on different
applications
- Performance and coding effort of high level tools against hand-coded
approaches on the GPU
- Performance and coding effort on multi-core CPUs against GPUs
utilizing programming abstractions
- Classification of different programming abstractions with respect to
their best application area

Submissions:
------------
The rules of PPAM conference apply. In particular:

- Papers will be refereed and accepted on the basis of their scientific
merit, relevance to the workshop topics, originality, correctness and quality
of presentation
- Papers presented at the Minisymposium will be included into the proceedings
and published after the conference by Springer-Verlag in the LNCS series
- Abstracts of accepted papers will be available during the conference
as a brochure or posted at the web.
- Regular papers are not to exceed 10 pages (LNCS style).
- Final camera-ready versions of accepted papers will be required by
October 31, 2011.
