    Data grids are currently proposed solutions to large-scale data management problems, including efficient file transfer and replication. Large amounts of data and the world-wide distribution of data stores contribute to the complexity of the data management challenge. Recent architecture proposals and prototypes deal with replication of read-only files but do not address the replica synchronisation... View full abstract»

    Considers the use of cooperative caching to manage the memories of cluster-based servers. Over the last several years, a number of researchers have proposed content-aware servers that implement locality-conscious request distribution to address this memory management problem. During this development, it has become conventional wisdom that cooperative caching cannot match the performance of these s... View full abstract»

    In recent years, there has been a dramatic increase in the amount of available computing and storage resources, yet few have been able to exploit these resources in an aggregated form. We present the Condor-G system, which leverages software from Globus and Condor to allow users to harness multi-domain resources as if they all belong to one personal domain. We describe the structure of Condor-G an... View full abstract»

    Distributed applications require information to effectively utilize the network. Some of the information they require is the current and maximum bandwidth, current and minimum latency, bottlenecks, burst frequency and congestion extent. This type of information allows applications to determine parameters like the optimal TCP buffer size. In this paper, we present a cooperative information-gatherin... View full abstract»

    A variety of projects worldwide are developing what we call "heterogeneous MPI". These MPI implementations are designed to operate on multiple computers, perhaps of different types, ranging in complexity from a set of desktop workstations to several supercomputers connected via a wide area network. These considerations led us to investigate the feasibility of defining a common API that could be us... View full abstract»

    Retrograde analysis is an efficient exhaustive search method. It is a powerful tool that can be used in solving problems where end states have known values but starting states do not. It has been widely used to solve mathematically-precise games such as chess endgames, and is potentially usable in energy-minimization problems. With increasing computing power, both in speed and storage capacity, re... View full abstract»

    Many high-performance distributed applications use only a small fraction of their available bandwidth. A common cause of this problem is not a flaw in the application design, but rather improperly tuned network settings. Proper tuning techniques, such as setting the correct TCP buffers and using parallel streams, are well-known in the networking community, but outside this community they are infre...

    The distributed searching of state spaces containing cycles is a challenging task and has been studied for several years. Traditional parallel search algorithms either ignore the cyclic nature of the state space and waste much time in duplicated search effort, or they rely on heavy communication to reduce duplicate work, resulting in a large communication overhead. Both methods perform poorly, eve... View full abstract»

    Different adaptive applications are interested in the dynamic behavior of a resource over different fine- to coarse-grain time-scales. The resource's sensor runs at some fine-grain resource-appropriate sampling rate, producing a discrete-time resource signal. It can be very inefficient to to answer a coarse-grain application query by directly using the fine-grain resource signal. We address this g... View full abstract»

    Active services are application-specified programs that are executed inside the network. The location where the active service is executed plays an important role. The dynamic behavior of networks requires that the selection of the most suitable location to instantiate a service is done at run time. To dynamically place an active service, information about the network (topology, bandwidth) and app... View full abstract»

  • Livelock avoidance for Meta-schedulers

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (600 KB) | HTML iconHTML

    Meta-scheduling, a process which allows a user to schedule a job across multiple sites, has a potential for livelock. Current systems avoid livelock by locking down resources at multiple sites and allowing a meta-scheduler to control the resources during the lock down period or by limiting job size to that which will fit on one site. The former approach leads to poor utilization; the later poses l... View full abstract»

    Data replication is a key issue in a data grid and can be managed in different ways and at different levels of granularity: for example, at the file level or the object level. In the high-energy physics community, data grids are being developed to support the distributed analysis of experimental data. We have produced a prototype data replication tool, the Grid Data Management Pilot (GDMP) that is... View full abstract»

    We present a benchmark suite for computational grids in this paper. It is based on the NAS Parallel Benchmarks (NPB) and is called the NAS Grid Benchmark (NGB). We present NGB as a data flow graph encapsulating an instance of an NPB code in each graph node, which communicates with other nodes by sending/receiving initialization data. These nodes may be mapped to the same or different Grid machines... View full abstract»

    Internet computing is facilitated by a remote execution methodology in which programs transfer to a destination for execution. Since the transfer time can substantially degrade the performance of remotely executed (mobile) programs, file compression is used to reduce the amount of data that is transferred. Compression techniques however, must trade off compression ratio for decompression time, due... View full abstract»
