    Notes: [Auszug] ...A growing number of sciences, from atmospheric modelling to genomics, would not exist in their current form if it were not for computers. A simplistic analysis of this relationship focuses on hardware, and sees science as largely a passive beneficiary of the computing industry's relentless ...

    Using computational grid capabilities to enhance the capability of an X‐ray source for structural biology (2000)

    Notes: Abstract The Advanced Photon Source at Argonne National Laboratory enables structural biologists to perform state-of-the-art crystallography diffraction experiments with high-intensity X-rays. The data gathered during such experiments is used to determine the molecular structure of macromolecules to enhance, for example, the capabilities of modern drug design for basic and applied research. The steps involved in obtaining a complete structure are computationally intensive and require the proper adjustment of a considerable number of parameters that are not known a priori. Thus, it is advantageous to develop a computational infrastructure for solving the numerically complex problems quickly, in order to enable quasi-real-time information discovery and computational steering. Specifically, we propose that the time-consuming calculations be performed in a “computational grid” accessing a large number of state-of-the-art computational facilities. Furthermore, we envision that experiments could be conducted by researchers at their home institution via remote steering while a beamline technician performs the actual experiment; such an approach would be cost-efficient for the user. We conducted a case study involving multiple tasks of a structural biologist, including data acquisition, data reduction, solution of the phase problem, and calculation of the final result - an electron density map, which is subsequently used for modeling of the molecular structure. We developed a parallel program for the data reduction phase that reduces the turnaround time significantly. We also distributed the solution of the phase problem in order to obtain the resulting electron density map more quickly. We used the GUSTO testbed provided by the Globus metacomputing project as the source of the necessary state-of-the-art computational resources, including workstation clusters.

    Managing security in high‐performance distributed computations (1998)
    Springer
    Cluster computing 1 (1998), S. 95-107

    Notes: Abstract We describe a software infrastructure designed to support the development of applications that use high‐speed networks to connect geographically distributed supercomputers, databases, and scientific instruments. Such applications may need to operate over open networks and access valuable resources, and hence can require mechanisms for ensuring integrity and confidentiality of communications and for authenticating both users and resources. Yet security solutions developed for traditional client‐server applications do not provide direct support for the distinctive program structures, programming tools, and performance requirements encountered in these applications. To address these requirements, we are developing a security‐enhanced version of a communication library called Nexus, which is then used to provide secure versions of various parallel libraries and languages, including the popular Message Passing Interface. These tools support the wide range of process creation mechanisms and communication structures used in high‐performance computing. They also provide a fine degree of control over what, where, and when security mechanisms are applied. In particular, a single application can mix secure and nonsecure communication, allowing the programmer to make fine‐grained security/performance tradeoffs. We present performance results that enable us to quantify the performance of our infrastructure.

    A fault detection service for wide area distributed computations (1999)

    Notes: Abstract The potential for faults in distributed computing systems is a significant complicating factor for application developers. While a variety of techniques exist for detecting and correcting faults, the implementation of these techniques in a particular context can be difficult. Hence, we propose a fault detection service designed to be incorporated, in a modular fashion, into distributed computing systems, tools, or applications. This service uses well-known techniques based on unreliable fault detectors to detect and report component failure, while allowing the user to trade off timeliness of reporting against false positive rates. We describe the architecture of this service, report on experimental results that quantify its cost and accuracy, and describe its use in two applications, monitoring the status of system components of the GUSTO computational grid testbed and as part of the NetSolve network-enabled numerical solver.

    Flat Parlog: A basis for comparison (1987)

    Notes: Abstract Three similar parallel logic programming languages have been proposed; Parlog, Flat Concurrent Prolog, and Guarded Horn Clauses. Quantitative comparison of the languages has not previously been possible since they employ different execution models and implementation techniques. In order to uncover the effects of semantic differences on efficiency, a common basis is required for experimentation. This paper presents a subset of the languageParlog calledFlat Parlog which provides a basis for quantitative comparison. The language combines the directional semantics of Parlog with the simple execution model of Flat Concurrent Prolog. A performance comparison between Flat Parlog and Flat Concurrent Prolog based on new implementations of both languages is presented. These new implementations are identical except for optimizations that are possible by virtue of semantic differences. Benchmark results indicate that Flat Parlog is more efficient; experiments have been able to quantify and explain this performance differential. A detailed description of the abstract machine for Flat Parlog is presented to illustrate the simplicity of the language.

    Implementing noncollective parallel I/O in cluster environments using Active Message communication (1999)

    Notes: Abstract A cost‐effective secondary storage architecture for parallel computers is to distribute storage across all processors, which then engage in either computation or I/O, depending on the demands of the moment. A difficulty associated with this architecture is that access to storage on another processor typically requires the cooperation of that processor, which can be hard to arrange if the processor is engaged in other computation. One partial solution to this problem is to require that remote I/O operations occur only via collective calls. In this paper, we describe an alternative approach based on the use of single‐sided communication operations such as Active Messages. We present an implementation of this basic approach called Distant I/O and present experimental results that quantify the low‐level performance of DIO mechanisms. This technique is exploited to support noncollective parallel shared file model for a large out‐of‐core scientific application with very high I/O bandwidth requirements. The achieved performance exceeds by a wide margin the performance of a well equipped PIOFS parallel filesystem on the IBM SP.

    A multicomputer garbage collector for a single-assignment language (1989)
    Springer
    International journal of parallel programming 18 (1989), S. 181-203

    ISSN: 1573-7640
    Keywords: Concurrent logic programming ; garbage collection ; weighted reference counting ; single-assignment languages ; multicomputers

    Notes: Abstract An asynchronous garbage collector for a message-passing multiprocessor (multicomputer) is described. This combines Weighted Reference Counting (WRC) interprocessor collection and tracing intraprocessor collection to permit individual processors to reclaim local storage independently. A novel feature is the integration of Weighted Reference Counting collection and the communication algorithms required to support a global address space in a single assignment language. This significantly reduces communication overhead and space requirements attributable to garbage collection. In addition, techniques are described that avoid the creation of cyclic structures that cannot be reclaimed using WRC. Experimental studies performed in a concurrent logic programming system that incorporates the collector confirm its efficiency and the benefits of integrating garbage collector and language implementation.
