A dynamic periodicity detector: application to speedup computation
(IEEE, 2001-04)
Text en actes de congrés
Accés obertWe propose a dynamic periodicity detector (DPD) for the estimation of periodicities in data series obtained from the execution of applications. We analyze the algorithm used by the periodicity detector and its performance ... -
A trace-scaling agent for parallel application tracing.
(IEEE, 2002)
Text en actes de congrés
Accés obertTracing and performance analysis tools are an important component in the development of high performance applications. Tracing parallel programs with current tracing tools, however, easily leads to large trace files with ... -
A demand based algorithm for rapid updating of replicas
(IEEE, 2002)
Text en actes de congrés
Accés obertIn many Internet scale replicated system, not all replicas can be dealt with in the same way, since some will be in greater demand than others. In the case of weak consistency algorithms, we have observed that updating first ... -
Open CSCW systems: will ODP help?
(IEEE, 1992-06-09)
Text en actes de congrés
Accés obertThis paper is concerned with the role of Open Distributed Processing systems within the development of cooperative systems. In particular, we focus on the need to provide Open CSCW systems and their impact on distributed ... -
WWG: a wide-area infrastructure to support groups.
(Association for Computing Machinery, 2001)
Text en actes de congrés
Accés obertGroup learning at Internet scale is becoming more frequent in university courses. This complex process requires support by distributed computing learning support infrastructures. This paper describes the design of WWG: a ... -
Decentralized vs. centralized economic coordination of resource allocation in grids
(Springer Verlag, 2003-02-13)
Text en actes de congrés
Accés obertApplication layer networks are software architectures that allow the provisioning of services requiring a huge amount of resources by connecting large numbers of individual computers, like in Grid or Peer-to-Peer ... -
ULabGrid, an infrastructure to develop distant laboratories for undergrad students over a Grid
(Springer Verlag, 2003-02-13)
Text en actes de congrés
Accés obertNowadays, there is a big discussion about two different topics: how distance learning and the old fashioned learning can be improved using the new technologies. In both cases, there are many collaborative tools based on ... -
Exploring the catallactic coordination approach for peer-to-peer systems
(Springer Verlag, 2003)
Text en actes de congrés
Accés obertEfficient discovery and resource allocation is one of the challenges of current Peer-to-Peer systems. In centralized approaches, the user requests can be matched to the fastest, cheapest or most available resource. This ... -
On the scalability of tracing mechanisms
(Springer Verlag, 2002)
Text en actes de congrés
Accés obertPerformance analysis tools are an important component of the parallel program development and tuning cycle. To obtain the raw performance data, an instrumented application is run with probes that take measures of specific ... -
MOCCA: an environment for CSCW applications.
(Association for Computing Machinery, 1993)
Text en actes de congrés
Accés obertOur belief is that future, Computer Supported Cooperative Work will by necessity involve a heterogeneous collection of applications, paradigms and models and that no single system will meet all the requirements of all ... -
Large event traces in parallel performance analysis.
(Springer Verlag, 2006)
Text en actes de congrés
Accés obertA powerful and widely-used method for analyzing the performance behavior of parallel programs is event tracing. When an application is traced, performancerelevant events, such as entering functions or sending messages, ... -
A methodology for user-oriented scalability analysis.
(IEEE, 1997-07-14)
Text en actes de congrés
Accés obertScalability analysis provides information about the effectiveness of increasing the number of resources of a parallel system. Several methods have been proposed which use different approaches to provide this information. ...
