Aim

With the rapid increase in the complexity and diversity of computing environments, from embedded systems and multicore processors to grid systems, development of software that can fully exploit the potential performance of the hardware has become a difficult and time-consuming task. As a means of overcoming this difficulty, automatic performance tuning technology to enable the software to self-adapt to the computing environments has recently aroused much interest.

Although there are several successful examples of automatic tuning, such as the ATLAS library (for basic linear algebra calculations) and the BeBOP project, this technology is still in its infancy. To further improve its effectiveness and expand its applicability, cooperation among researchers in various fields such as computer science, software engineering, mathematics and statistics is essential.

The iWAPT2007 is the second of a series of international workshops that focuses on automatic tuning technology. The goal of this workshop is to provide opportunities for researchers and practitioners in all fields related to automatic performance tuning to exchange ideas and experiences. Papers reporting original ideas and results are solicited. Invited talks by leading researchers are also planned.


Topics of Interest

  • Performance modeling and automatic tuning of, for, and in:
      - Numerical algorithms, libraries and systems,
      - Parallel, distributed and networked processing grids,
      - Scientific and engineering applications,
      - Computer graphics, database systems and robotics,
      - Precision, stability, memory consumption and low-power systems,
      - Real-time, fault tolerant and dependable processing,
      - Embedded systems, GPU, accelerators, and performance of emerging architectures,
      - Context-aware computing,
      - Autonomic computing for high performance applications.
  • Performance evaluation and modeling, prediction benchmarking and performance database
  • Languages, compilers and programming tools for automatic performance tuning
  • Automatic performance tuning as/for software engineering
  • Systems, middleware and libraries for automatic performance tuning
  • Frameworks, mathematics and theories for automatic performance tuning
  • Experimental design and statistics for automatic performance tuning
  • Theory and methods of optimization for automatic performance tuning
  • Multi-objective tuning, tuning under constraints

Paper Submission and Publication Plan (now closed)

Extended abstracts (10pt, single-column, a maximum of 3,000 words) on a wide range of automatic performance tuning topics (as listed above) are welcome. All manuscripts will be reviewed and judged on merits including correctness, originality, technical accuracy, quality of presentation, and relevance to the workshop. Authors should submit the extended abstract electronically (PDF or PS) to iWAPT2007-sub_at_kata-lab.itc.u-tokyo.ac.jp (replacing "_at_" by "@" in the email address). We are currently planning the publication of after-conference proceedings from some major publisher through a second review process after the workshop. 

Poster Submission and Presentation (now closed)

Abstracts (10pt, single-column, a maximum of 300 words, one A4-page) on a wide range of automatic performance tuning topics (as listed above) are welcome. The manuscripts should include the following:

  • Title of the poster.
  • Names, affiliations, and contact information of the authors, with one identified as the primary contact.
  • Detailed description of the poster and the references.


Submissions will be reviewed by the committee and evaluated in terms of interest to the audience. If accepted, the abstract as it is will be used as a camera-ready manuscript for inclusion in the conference proceedings. Authors should submit the abstract electronically (in PDF or PS format) to iWAPT2007-sub_at_kata-lab.itc.u-tokyo.ac.jp (replacing "_at_" by "@" in the email address).

The authors are responsible for the printing of display material. The poster board size is 110cm width by 170cm height. A table for PC demonstration with 100V electricity and wireless LAN can be provided on prior request. In addition, the iWAPT2007 conference has an indexing session of the poster presentaions. The authors are also responsible for the five minutes talk of the material.
