    A grid scheduler maps efficiently the resources, available to a grid resource-service provider, to the applications submitted by the users. For efficient mapping, the scheduler should be able to use the information about the availability of computeresources and communication resources,communication delays, the application and the communication latencies and prior reservation of resources, if any. ...

    The use of ontologies to express the attributes of grid resources can provide a means to explore knowledge in this environment. Unfortunately, many grid initiatives have built their own ontologies, which are incompatible with the others. To achieve interoperability, ontology merge is a very interesting alternative. In this paper, we propose and evaluate a mechanism that performs ontology merging a... View full abstract»

    To more effectively use HPC clusters for even larger computations, improve turn-around times and better utilize compute resource, users are looking to interconnect multiple HPC clusters, creating a grid. To effectively use such grids, it may be desirable to split and co-allocate jobs requiring many processes across multiple clusters. While splitting a very large job across multiple clusters is an ...

    The operation of modern distributed enterprises, be they commercial, scientific, or health related, generate massive quantities of data. Decision makers increasingly utilize On- Line Analytical Processing (OLAP) tools to glean from this rich data resource nuggets of information which can be used to better run their enterprises. A typical approach to OLAP is to construct a single centralized data r... View full abstract»

    The high heterogeneity of grid resources, diversity of politics of access and publication of characteristics are examples on how it is difficult to primarily select grid resources based on requirements of an application. Another aspect that can illustrate the challenge is the flexibility to accept new resources that become dynamically available inside a configuration. On the other hand, some appli...

    For complex processes investigated in scientific fields such as medicine and earth sciences, knowledge discovery that exposes the underlying structure of the processes is crucial for detecting changes of state and constructing forecasting procedures. A model discovery approach has been recently developed, which uses computational intelligence techniques to deal with the heterogeneity, incompletene... View full abstract»

    In the last decade, personal computers became more powerful and less expensive, and the development of Internet increased the connectivity of these machines. This situation opened many opportunities in the distributed computing world. Some projects such as SETI@home were launched to perform scientific computations on temporarily unused workstations. However, in most cases, the distributed computin... View full abstract»

    Several interconnection networks (such as meshes and hypercubes) can be modeled as circulant graphs. As a result, methods previously developed for constructing fault-tolerant solutions of circulant graphs can also be applied to these networks. Among these methods, the one based on the idea of "offsets partitioning" is the most efficient (for circulant graphs). We review this method in this paper, ... View full abstract»

    As low-cost multiprocessing reaches a wider market, a greater number of programmers will need to be trained for parallel programming. Current studies exploring usability engineering for parallel programming focus only on experienced parallel programmers. This paper applies the card sorting method used in psychology research to understanding the software needs of the novice parallel programmer. Thi... View full abstract»

    Developing parallel and distributed programs is usually considered a hard task. One has to have a good understanding of the problem domain, as well as the target hardware, and map the problem to the available hardware resources. The resulting program is often hard to port to another system. The development and maintenance process may thus be costly and time-consuming. In this paper we propose givi... View full abstract»

    Researchers may find it difficult to run experiments on High Performance Computing Systems (HPCS) if they are unfamiliar with terminals and UNIX/Linux commands. Instead of using available HPCS resources, they may choose to run experiments on their personal computers, even if it takes them weeks to run small jobs. However, these researchers are familiar with using the Internet on a daily basis to c... View full abstract»

    GridX1 is a computational grid deployment of off-theshelf components using shared resources at several Canadian research institutions. This work evaluates the applicability of knapsack-based resource scheduling to real grids, such as GridX1, by simulating the execution of a real job trace (the NPACI JOBLOG). The task interarrival time is scaled to demonstrate the benefits of the knapsack strategy ... View full abstract»

    Many astrophysical systems have important behaviors on scales so disparate that even modern techniques such as adaptive mesh refinement cannot possibly resolve all of the dynamics. However, there are situations where the interactions between the scales are relatively simple; in these cases the system can be meaningfully decomposed into different sub-problems, which can be separately understood and...
