Micro-Grids: Practical Applications of Grid Technology to
Small Distributed Collaborations

Abstract. Recently there has been a great deal excitement about using both
Computational and Data Grids [1,9], for large-scale scientific computing. However,
the utility of Grid tools, ideas, and technologies to solve smaller-scale problems is
often overlooked. In this paper, it will be shown not only that grids work very well
for these smaller problems, but that the techniques developed for use in large scale
grid computing can be applied equally as well to smaller problems and used in a
effective and productive manner. This paper focuses on what Grid technology can be
used to address a specific problem, particularly the aspects of monitoring a Grid and
the associated problems and solutions. This will be described in the context of a
scientific collaboration between six geographically distinct sites that spanned both
the East and West coasts of the United States.
Introduction
In the research field of Micro-Electro-Mechanical Systems (MEMS), there are two
major practical obstacles to experimental progress. The first is that fabrication and testing
facilities are a scarce resource: only a handful of well-funded academic and government
research programs have the equipment necessary to fabricate and perform experiments on-
site, and commercial facilities are very expensive. The second obstacle is that scientists
have difficulty sharing the results of their experiments with the rest of the community
because the datasets are large, there is no common format for experimental results, and
there is no uniform way of describing the experiment that produced the data. The solution
to these problems is coordinated and transparent remote access to MEMS instruments and
the resulting data from of MEMS experiments. This includes interactive control of test
instruments, and a shared system for documenting experimental results so that they can
later be retrieved with automated tools. The following sections will describe how Grid
concepts, tools, and technologies were used to implement this solution in a DARPA-
funded collaboration called Matisse [12] that involved (from West to East) the University
of California at Berkeley (UCB), Lawrence Berkeley National Laboratory (LBNL),
