BioTeam first became interested in Univa UD’s software efforts after hearing Univa CTO Steve Tueckespeak in Regensburg, Germany at the 2007 Grid Engine workshop. Shortly after that event Univa formally became Univa UD after merging with United Devices. At the time, Steve’s company seemed to be one of the few companies positioning themselves to offer full support and professional services encompassing commonly used open source products such as Sun Grid Engine that BioTeam often works with in the field. Individually these popular open source resources are relatively easy to acquire but Univa UD seemed to be making an interesting effort to become the one stop shop for a fully supported and integrated set of commonly required tools and technology.

In both e-business and e-science, we often need to integrate services across distributed, heterogeneous, dynamic “virtual organizations” formed from the disparate resources within a single enterprise and/or from external resource sharing and service provider relationships. This integration can be technically challenging because of the need to achieve various qualities of service when running on top of different native platforms. We present an Open Grid Services Architecture that addresses these challenges.

Emerging high-performance applications require the ability to exploit diverse, ge- ographically distributed resources. These applications use high-speed networks to in- tegrate supercomputers, large databases, archival storage devices, advanced visualiza- tion devices, and/or scienti?c instruments to form networked virtual supercomputers or metacomputers. While the physical infrastructure to build such systems is becoming widespread, the heterogeneous and dynamic nature of the metacomputing environment poses new challenges for developers of system software, parallel tools, and applications. In this article, we introduce Globus, a system that we are developing to address these challenges.

What is the Grid? How are Grids built and used (today)? What Grid software is available and what does it do? BREAK (somewhere during part III) How have others succeeded? History For years, a few whacky computer scientists have been trying to help other scientists use distributed computing. Interactive simulation (climate modeling) Very large scale simulation and analysis (galaxy formation, gravity waves, battlefield simulation) Engineering (parameter studies, linked component models) Experimental data analysis (high-energy physics) Image and sensor analysis (astronomy, climate study, ecology) Online instrumentation (microscopes, x-ray devices, etc.)

Fundamentals and concepts Using the Globus Toolkit OGSA introduction Grid computing, most simply stated, is distributed computing taken to the next evolutionary level. The goal is to create the illusion of a simple yet large and powerful self managing virtual computer out of a large collection of connected heterogeneous systems sharing various combinations of resources. The standardization of communications between heterogeneous systems created the Internet explosion.

Install and run examples Open Grid Services Infrastructure compliant You are a scientist, a businessperson, or an engineer. You are always looking for faster ways to do your computer processing, better ways to store and retrieve your data, more efficient ways to interact with your customers or suppliers or clients, all while spending less money. You may be asking yourself these questions, among others: How can I analyze the value of an investment portfolio in minutes, rather than hours? How can I significantly accelerate the drug discovery process?
