With the emergence of the cloud computing paradigm, there will be an increased reliance on wireless communication from portable computing devices to more powerful centralized servers. This paradigm shift to `thin-clients' presents an opportunity to make portable computing more sustainable by shifting more functionality to centralized servers. Reduced functionality needed on these devices could mean a slower rate of hardware replacement. This could significantly cut the electronic waste that is currently attributed to the frequent replacements of these devices. One of the challenges in such a paradigm shift to thin portable clients through reduced local computation would be the additional burden imposed on the wireless communication technologies used. Wireless communication technologies must be improved to handle the additional burden that will be imposed. Any proposed wireless technology must also be energy-efficient to maximize the operating life time of these battery operated, energy-constrained devices. Software approaches to achieve energy-efficient operation are preferable as they reduce the dumping of existing hardware due to upgrades or replacements, and help reduce electronic waste. This paper discusses these challenges and describes one way to move forward towards sustainable portable computing by considering application scenarios based on cloud computing and communication through software-defined cognitive radios.","PeriodicalId":415472,"journal":{"name":"2010 39th International Conference on Parallel Processing Workshops","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133167439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has proved difficult to apply existing techniques to live data centers because of models that are either unrealistic, require extensive sensing instrumentation, or because their creation is disruptive to the data center services. The work presented in this paper discusses techniques and their associated challenges with respect to creating an adaptive and non-invasive method of creating realistic and low-complexity thermal models using built-in and ambient sensors. Uses of these techniques can vary from assessing the thermal efficiency of the data center to designing a thermal-aware job scheduler to lower total cost of ownership (TCO). Specifically, this paper proposes: i) a non-invasive thermal modeling software architecture that uses on-board, ambient and software sensors ii) and four different ways of leveraging the gathered data from an experimental application of the architecture to improve the greenness of the data center and our understanding of the thermal behavior of a data center.","PeriodicalId":415472,"journal":{"name":"2010 39th International Conference on Parallel Processing Workshops","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133907978","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many tools exist for measuring and analyzing the runtime performance of applications. Obtaining sufficiently detailed performance data and comparing it with the peak performance of an architecture are one path to understanding the behavior of a particular algorithm implementation. A complementary approach relies on the analysis of the source code itself, coupling it with a simplified architecture description to arrive at performance estimates that can provide a more meaningful upper bound than the peak hardware performance. We present a tool for estimating upper performance bounds of C/C++ applications through static compiler analysis. It generates parameterized expressions for different types of memory accesses and integer and floating-point computations. We then incorporate architectural parameters to estimate upper bounds on the performance of an application on a particular system. We present validation results for several codes on two architectures.","PeriodicalId":415472,"journal":{"name":"2010 39th International Conference on Parallel Processing Workshops","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121918244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experts tune such applications to use hierarchical memory subsystems efficiently. Hardware accelerators, such as GPUs, can potentially improve memory performance beyond the capabilities of traditional hierarchical systems. However, the addition of such specialized hardware complicates code porting and tuning. During porting and tuning expert application engineers manually browse source code and identify memory access patterns that are candidates for optimization and tuning. HPC applications typically contain thousands to hundreds of thousands of lines of code, creating a labor-intensive challenge for the expert. PIR, PMaC’s Static Idiom Recognizer, automates the pattern recognition process. PIR recognizes specified patterns and tags the source code where they appear using static analysis. This paper describes the PIR implementation and defines a subset of idioms commonly found in HPC applications. We examine the effectiveness of the tool, demonstrating 95% identification accuracy and present the results of using PIR on two HPC applications.","PeriodicalId":415472,"journal":{"name":"2010 39th International Conference on Parallel Processing Workshops","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116732248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, communication systems, including cellular networks, were usually crashed due to various causes making the coordination among a large number of disorganized disaster response workers extremely difficult. Unfortunately, rapid deployment of many existing emergency communication systems relies on a good transportation system, which is usually not available in a catastrophic natural disaster. We designed a multi-hop walkie-talkie-like communication system based on P2Pnet platform, which is a MANET P2P network constructed using volunteers’ laptops. This system can support a large number of voluntary workers in the early hours of a catastrophic natural disaster when external assistance is blocked by the paralyzed transportation system. The multi-hop version can help to bypass the obstacles that block face-to-face communication as well as direct WiFi communication links. We wish to stimulate the research on the emergency communication systems that is inexpensive and easy to deploy for future catastrophic natural disasters.","PeriodicalId":415472,"journal":{"name":"2010 39th International Conference on Parallel Processing Workshops","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114824566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A Wireless Sensor and Actor Network (WSAN) has a set of sensor nodes for monitoring events and a set of high capability nodes, called actor nodes, for reacting to the events. It can provide an infrastructure for building the intrusion detection system in a smart home. We need to jointly consider fault-tolerance and timeliness issues because sensor nodes are likely to be influenced by failures (e.g., dead battery) and need to deliver packets in real time over wireless links vulnerable to interference caused by walls, floors or furniture. In this paper, we propose Optimal Multipath Planning (or OMP), which is based on Edmonds-Karp maximum flow algorithm and Goldberg and Tarjan minimum cost flow algorithm, for WSANs to set up paths to deliver intrusion event notification from event sources to actors in a smart home. The planning is optimal in the sense that it sets up the maximum number of node-disjoint paths of links with the minimized expected transmission count (ETX). We also evaluate OMP’s performance by simulations and compare it with the minimum cost planning using Dijkstra algorithm to show its advantages.","PeriodicalId":415472,"journal":{"name":"2010 39th International Conference on Parallel Processing Workshops","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123044081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
