Cooperative checkpointing for supercomputing systems
A system-level checkpointing mechanism, with global knowledge of the state and health of the machine, can improve performance and reliability by dynamically deciding when to skip checkpoint requests made by applications. This thesis presents such a technique, called cooperative checkpointing, and …

A Descriptive Performance Model of Small, Low Cost, Diskless Beowulf Clusters
<p>Commodity supercomputing clusters known as Beowulf clusters, have become a low cost alternative to traditional supercomputers. Beowulf clusters combine inexpensive computers and specialized software to achieve supercomputing power. The processing nodes in a diskless Beowulf cluster do not have a …

Self-scheduling, data synchronization and program transformation for multiprocessor systems
The limitation of vector supercomputing and of device speed has led to the development of multiprocessor supercomputers. Although large tightly-coupled shared-memory multiprocessor systems have become feasible, such systems cannot be considered successful, unless their numerous processors can …

Matrix multiplication with Asynchronous Logic Automata
A longstanding trend in supercomputing is that as supercomputers scale, they become more difficult to program in a way that fully utilizes their parallel processing capabilities. At the same time they become more power-hungry - today's largest supercomputers each consume as much power as a town of …
