“…The probe itself is a simple shell script requiring a single core that is submitted through the nanoHUB jo submission process in the same manner as a production application run. In most cases the probe will wait in a batch queuing time prediction, as well as detection of problems in the [3], and TeraGrid's provide information system performance while INCA [5] provides automated testing and monitoring of the grid Yoshimoto [6] evaluated the performance of a variety of resource selection tools against jobs sent to TeraGrid resources and found that the tools do provide improvement over random er, the variety of computing resources utilized by nanoHUB required a more general approach, which we…”

In 2010, the science gateway nanoHUB.org, the world's largest nanotechnology user facility, hosted 9,809 simulation users who performed 372,404 simulation runs. Many of these jobs are compute-intensive runs that benefit from submission to clusters at Purdue, TeraGrid, and Open Science Grid (OSG). Most of the nanoHUB users are not computational experts but end-users who expect complete and uninterrupted service. Within the ecology of grid computing resources, we need to manage the grid submissions of these users transparently with the highest possible degree of user satisfaction. In order to best utilize grid computing resources, we have developed a grid probe protocol to test the job submission system from end to end. Beginning in January 2009, we have collected a total of 1.2 million probe results from job submissions to TeraGrid, OSG, Purdue, and nanoHUB compute clusters. We then utilized these results to intelligently submit jobs to various grid sites using a model for probability of success based in part on probe test history. In this paper we present details of our grid probe model, results from the grid probe runs, and a discussion of data from production runs over the same time period. These results have allowed us to begin assessing our utilization of grid resources while providing our users with satisfactory outcomes.

“…Similarly, science portal systems do not easily fit within a traditional ''white-box'' style of unit testing, which assumes knowledge of the source code of all parts of the system, since they depend both on remote clients (users' browsers) and remote Web services that in turn wrap binary executables. The Inca project (SMALLEN et al, 2004) is an example effort in Grid testing and monitoring. User interface-driven testing, such as is needed by science portals, is an open area of systems research, but can be very useful as a way of encapsulating composite tests that simulate real usage scenarios.…”

Abstract-We describe our distributed systems research efforts to build the ''cyberinfrastructure'' components that constitute a geophysical Grid, or more accurately, a Grid of Grids. Service-oriented computing principles are used to build a distributed infrastructure of Web accessible components for accessing data and scientific applications. Our data services fall into two major categories: Archival, database-backed services based around Geographical Information System (GIS) standards from the Open Geospatial Consortium, and streaming services that can be used to filter and route real-time data sources such as Global Positioning System data streams. Execution support services include application execution management services and services for transferring remote files. These data and execution service families are bound together through metadata information and workflow services for service orchestration. Users may access the system through the QuakeSim scientific Web portal, which is built using a portlet component approach.

“…Inca [25] is a flexible framework for performing periodic user-level functionality testing and performance measurement of Grid systems. It consists of a reporter repository that contains a collection of reporters (i.e., test programs), reporter managers that are responsible for managing the schedule and execution of reporters on resources, and a depot that is responsible for storing the data produced by reporters.…”

Due to the dynamic characteristics and heterogeneity of Grid resources, effective and accurate Grid resource monitoring and discovery are a challenging problem. To deal with this, the semantic Grid extends the current Grid by giving information and services well-defined meaning through machine-processable descriptions. In this paper, we present a monitoring and discovery system that is based on the semantic Grid built on the top of the WS-Resource Framework. The system provides an infrastructure to create, aggregate, and maintain semantic metadata of Grid resources so that they can be semantically queried using Resource Description Framework query languages such as SPARQL. We present the system architecture and optimization methods to maintain and store the semantic metadata. Through a system M. P. Said · I. Kojima implementation based on the Globus Toolkit software, we show the practicality and simplicity of the framework. We also present evaluation results showing the effectiveness and robustness of the system.
