— We have extended the Falkon execution framework to make loosely coupled petascale systems a practical and useful prog This work studies and measures the perf involved in applying this approach to enable th systems by a broader user community, and w Our work enables the execution of highly para composed of loosely coupled serial jobs with no the respective(More)
SUMMARY The first Provenance Challenge was set up in order to provide a forum for the community to understand the capabilities of different provenance systems and the expressiveness of their provenance representations. To this end, a Functional Magnetic Resonance Imaging workflow was defined, which participants had to either simulate or run in order to(More)
Many-task computing aims to bridge the gap between two computing paradigms, high throughput computing and high performance computing. Many-task computing denotes high-performance computations comprising multiple distinct activities, coupled via file system operations. The aggregate number of tasks, quantity of computing, and volumes of data may be extremely(More)
wilde at mcs dot anl dot gov The kickstart executable is a lightweight program that is distributed as part of the GriPhyN Virtual Data System. It sits in between the remote scheduler and the executable, gathering additional information about the executable run-time behavior, including, but not limited to, the exit status of jobs and information to ease grid(More)

The Open Science Grid (OSG) includes work to enable new science, new scientists, and new modalities in support of computationally based research. There are frequently significant sociological and organizational changes required in transformation from the existing to the new. OSG leverages its deliverables to the large-scale physics experiment member(More)
Naturally occurring proteins with similar sequences generally posses similar structures and often perform similar functions. Consequently, multiple sequence alignments are used to discern homologous structures for application in template-based modeling and in methods where structures are assembled using homologous fragments. While these homology-based(More)
In grid environments, the deployment and management of application software presents a major practical challenge for end users. Performing these tasks manually is error-prone and not scalable to large grids. In this work, we propose an automation tool, ADEM, for grid application software deployment and management, and demonstrate and evaluate the tool on(More)
Overview With the advances in e-Sciences and the growing complexity of scientific analyses, more and more scientists and researchers are relying on workflow systems for process coordination, derivation automation, provenance tracking, and bookkeeping. Workflows are not a new concept and have been around for decades [1][3][6][7][2]. In the scientific(More)
