This white paper is aimed at creating a directory of existing performance monitoring and evaluation tools. The detailed categorization enables finding relevant properties, similarities and differences, and comparing the tools. The paper is neutral: there are no comments or assessment. The catalogue helps grid users, developers, and administrators in finding(More)
Automatic composition of workflows from Web and Grid services is an important challenge in today's distributed applications. The system presented in this paper supports the user in composing an application workflow from existing Grid services. The flow composition system builds workflows on an abstract level with semantic and syntactic descriptions of(More)
Human immunodeficiency virus (HIV) is recognized to be one of the most destructive pandemics in recorded history. Effective highly active antiretroviral therapy and the availability of genetic screening of patient virus data have led to sustained viral suppression and higher life expectancy in patients who have been infected with HIV. The sheer complexity(More)
Can the Google App Engine cloud service be used, free of charge, to execute parameter study problems? That question drove this research, which is founded on the App Engine's newly developed Task Queue API. The authors created a simple and extensible framework implementing the master-worker model to enable usage of the App Engine application servers as(More)
The CrossGrid project will develop, implement and exploit new Grid components for interactive compute and data intensive applications like simulation and visualisation for surgical procedures, flooding crisis team decision support systems, distributed data analysis in high-energy physics, air pollution combined with weather forecasting.
