Exposing disk layout to compiler for reducing energy consumption of parallel disk based systems

S. W. Son, G. Chen, M. Kandemir, A. Choudhary
2005 Proceedings of the tenth ACM SIGPLAN symposium on Principles and practice of parallel programming - PPoPP '05  
Motivated by this observation, this paper proposes and evaluates a compiler-driven approach to reducing disk power consumption of array-based scientific applications executing on parallel architectures  ...  The proposed approach exposes disk layout information to the compiler, allowing it to derive disk access pattern, i.e., the order in which parallel disks are accessed.  ...  One of the requirements for being able to use a compiler in reducing disk power consumption is to capture how parallel disks are accessed at a high level (i.e., source code level).  ...

Inter-program Compilation for Disk Energy Reduction [chapter]

Jerry Hom, Ulrich Kremer
2005 Lecture Notes in Computer Science  
Compiler support for power and energy management has been shown to be effective in reducing overall power dissipation and energy consumption of individual programs, for instance through compilerdirected  ...  A preliminary study and simulation results for this inter-program compilation approach shows that significant disk energy can be saved (between 5% and 16%) over the individually, disk energy optimized  ...  We aim to construct a general framework suitable for developing resource optimizations across applications to reduce energy and power consumption.  ...

Network-Aware Program-Counter-Based Disk Energy Management [chapter]

Igor Crk, Chris Gniady
2009 Studies in Computational Intelligence  
Our dynamic mechanisms reduce the decision delay before the disk is spun-up, reduce the number of erroneous spin-ups in local workstations, decrease the network bandwidth, and reduce the energy consumption  ...  We propose a network-aware energy management mechanism that provides a low-cost solution that can significantly reduce energy consumption in the entire system while maintaining responsiveness of local  ...  By eliminating disk spin-ups we can significantly reduce both the client's power consumption and the wear-and-tear of the disk's mechanical components.  ...

Design techniques for low-power systems

Paul J.M Havinga, Gerard J.M Smit
2000 Journal of systems architecture  
Because these systems are battery powered, reducing power consumption is vital.  ...  In this report we give the properties of low power design and techniques to exploit them on the architecture of the system.  ...  For example, a energy efficient architecture that occupies a larger area can reduce the overall energy consumption, e.g. by exploiting locality in a parallel implementation.  ...

Parallel database systems: Open problems and new issues

Patrick Valduriez
1993 Distributed and parallel databases  
Furthermore, it is still an open issue to decide which of the various architectures among sharedmemory, shared-disk, and shared-nothing, is best for database management under various conditions.  ...  Finally, there are new issues raised by the introduction of higher functionality such as knowledge-based or object-oriented capabilities within a parallel database system.  ...  This partitioning is typically defined during the physical database design and then exploited by a compiler.  ...

Power reduction techniques for microprocessor systems

Vasanth Venkatachalam, Michael Franz
2005 ACM Computing Surveys  
Power consumption is a major factor that limits the performance of computers. We survey the "state of the art" in techniques that reduce the total power consumed by a microprocessor system over time.  ...  They also include holistic approaches that will become more important over the next decade.  ...  For example, it may be expensive to access data resident on a disk if the disk is powered down and would take a long time to restart.  ...
