Teabag: A Debugger For Curry, Stephen Lee Johnson
Teabag: A Debugger For Curry, Stephen Lee Johnson
Dissertations and Theses
This thesis describes TeaBag, which is a debugger for functional logic computations. TeaBag is an accessory of a virtual machine currently under development. A distinctive feature of this machine is its operational completeness of computations, which places novel demands on a debugger. This thesis describes the features of TeaBag, in particular the handling of non-determinism, the ability to control nondeterministic steps, to remove context information, to toggle eager evaluation, and to set breakpoints on both functions and terms. This thesis also describes TeaBag's architecture and its interaction with the associated virtual machine. Finally, some debugging sessions of defective programs are …
Infrastructure For Performance Tuning Mpi Applications, Kathryn Marie Mohror
Infrastructure For Performance Tuning Mpi Applications, Kathryn Marie Mohror
Dissertations and Theses
Clusters of workstations are becoming increasingly popular as a low-budget alternative for supercomputing power. In these systems,message-passing is often used to allow the separate nodes to act as a single computing machine. Programmers of such systems face a daunting challenge in understanding the performance bottlenecks of their applications. This is largely due to the vast amount of performance data that is collected, and the time and expertise necessary to use traditional parallel performance tools to analyze that data.
The goal of this project is to increase the level of performance tool support for message-passing application programmers on clusters of workstations. …
