HotPower

4th Workshop on Power-Aware Computing and Systems

HotPower'11 will be held immediately before the 23nd ACM Symposium on Operating Systems Principles (SOSP'11).

Important Dates

  • Paper submissions due: Extended to Fri, Jun 17, 2011, 11:59PM EDT
  • Notification to authors: Mon, Jul 25, 2011
  • Camera ready due: Wed, Aug 3, 2011
  • Workshop: October 23, 2011

Overview

Power has become a central issue in the design of modern computer systems.  It affects a wide variety of systems, including mobile devices, embedded networks, and data centers.  However, we do not yet fully understand the tradeoffs between energy, performance, cost, and other metrics in these environments.  This limits our ability to improve energy-efficiency without violating performance requirements and physical constraints (e.g., battery or cooling capacity).
HotPower provides a forum in which to present the latest research and to debate directions, challenges, and novel ideas about building energy-efficient computing systems.  In addition, researchers coming to these issues from fields such as computer architecture, systems and networking, measurement and modeling, language and compiler design, mobile computing, and embedded systems will have the opportunity to interact with one another, explore cross-cutting ideas, and develop new perspectives on the problem domain.

Topics

Topics of interest in energy-efficient computing include but are not limited to:

  • Instrumentation, measurement, and measurement studies
  • Energy and performance profiling, accounting
  • Metrics, benchmarks, interfaces
  • Principles of power management
  • Performance, energy and other resource trade-offs, energy complexity
  • Compiler optimization, application design
  • System-level optimization, cross-layer coordination
  • Load and resource modeling, management
  • Scheduling, run-time adaptation, feedback control
  • Processor, network, storage, hardware components and architecture
  • Reliability and power management
  • Application to multi-core, data center, and embedded systems
  • Green energy sources and their implications

The workshop encourages submissions of early-stage research and novel ideas that have a high likelihood of generating interesting discussion.

    Submission Instructions

    Submitted papers must be no longer than 5 single-spaced 8.5" x 11" pages, including figures, tables, and references; two-column format, using 10-point type on 12-point (single-spaced) leading; and a text block 6.5" wide x 9" deep.  Author names and affiliations should appear on the title page.  The class file sig-alternate-hotpower11.cls meets these formatting guidelines. Papers must be in PDF format and must be submitted via the Web submission form:

    http://power.eecs.umich.edu/hotpower11/

    Simultaneous submission of the same work to multiple venues, submission of previously published work, or plagiarism constitutes dishonesty or fraud.  Papers meeting any of these criteria will be rejected. Authors uncertain whether their submission meets these guidelines should contact the program chairs.

    Papers accompanied by nondisclosure agreement forms will not be considered.  Accepted submissions will be treated as confidential prior to publication on the HotPower'11 Web site; rejected submissions will be permanently treated as confidential.
