The Eighth Workshop on
High-Performance, Power-Aware Computing
May 21, 2012, Shanghai, China
The 8th Workshop on High-Performance, Power-Aware Computing (HPPAC 2012) will be held on May the 21st, 2012 in Shanghai, China, in conjunction with the
26th Annual
International Parallel & Distributed Processing Symposium (IPDPS 2012), to be held on May 21-25, 2012, Shanghai, China.
Scope
High-performance computing is and has always been performance-oriented.
However, a consequence of the push towards maximum performance is
increased energy consumption, especially in datacenters and
supercomputing centers. Moreover, as peak performance is rarely
attained, some of this energy consumption results in little or no
performance gain. In addition, large energy consumption costs
datacenters and supercomputing centers a significant amount of
money and wastes natural resources.
The main goal of this workshop is to provide a timely forum for the
exchange and dissemination of new ideas, techniques, and research in
high-performance, power-aware computing (HPPAC). HPPAC will present
research that reduces (1) power consumption, (2) energy consumption,
or (3) heat generation with little or no performance penalty in
high-performance computing systems. In effect, the workshop aims to
move towards "greener" solutions for
datacenters and supercomputing centers. Examples include
Green Destiny (2001),
The Green Grid (2007),
The Green500 List (2007), and the
INRIA Green-Net Initiative (2008).
Submission Guidelines
All papers should not exceed 8 single-spaced, double column pages (US Letter)
in 10pt font. All papers will be reviewed. Accepted papers will appear in the
printed program book and CD-ROM proceedings of the main conference,
IPDPS2012. Click here to submit a paper.
Program
| 9.00-10.00 | Keynote (Chair: Bronis R. de Supinski) |
| | Towards Green-HPC : (some) challenges, approaches and expectations
Laurent Lefevre (INRIA) - BIO
Energy has recently become one of the main limiting factor for designing large scale distributed systems. This talk will overview some current approaches for designing energy efficient systems (coming from recent activities in GreenTouch, PrimeEnergyIT, CompatibleOne and XLCloud projects). Some focus will be proposed on energy efficiency in virtualized environments and on Green Exascale services.
