in Multi-Use Clusters of PCs.

The trend to use the same or similar commodity
components in all new architectures from a laptop to the largest supercomputers
caused a highly welcome acceleration of growth in performance and decrease in
price due to the high volume of these components. The annual increase in the
amount of compute performance and disk storage capacities at the same or lower
cast is just incredible.lt is therefore highly
important that we learn how to design a system under the constraint of
commodity components and that we aim to use the widely available compute and
storage resources in a more flexible and intelligent way.ln
this thesis the author postulates a generalised view
of all installed IT resources (processors, storage and network) in the form of
"multi-use clusters of commodity PCs".
To achieve this vision, the operating-system installation of the previously isolated computers must support a flexible and distributed resource management. In order to achieve this by scientific means, the thesis introduces a few fundamental technologies including (a) an analytic model to optimise the streams while distributing large data sets in clusters of PCs, (b) a simple software tool to distribute disk images, which derived from the model and its principle, (c) an efficient storage scheme für archiving software-installation images in an operating-system-independent way and (d) several implementations and a rigorous classification of a variety of distributed storage solutions based on file systems and distributed devices. While the first technologies enable a more flexible management of multi- use clusters, the latter technologies allow für a more efficient use of all unused disk space in multi-use clusters.
