Tiling optimizations for stencil computations
This thesis studies the techniques of tiling optimizations for stencil programs. Traditionally, research on tiling optimizations mainly focuses on tessellating tiling, atomic tiles and regular tile shapes. This thesis studies several novel tiling techniques which are out of the scope of traditional …

Cache optimizations for stream programs
… StreamIt. This thesis presents four memory optimizations: 1) cache aware fusion, which combines adjacent program components while respecting instruction and data cache constraints, 2) execution scaling, which judiciously repeats execution of program components to improve instruction and …

Charge-coupled device optimizations for astronomy.
In the past decade, charge-coupled devices (CCDs) have rapidly become the astronomical imaging detector of choice for the visible and near-IR spectral regions. There are, however, several problems which have greatly reduced the availability of sufficient quality CCDs to the astronomical community. …

Optimizations in Distributed Run -Time Compilation
We also consider possibilities for optimizations, and present a rewriting system for Java abstract syntax trees designed to optimize the code generators. This general-purpose optimizer exploits the compositional nature of Jumbo to aggressively optimize the code generators for the individual code …

Applied Compiler Optimizations for Proving Code
The recent popularity of massively distributed, trustless systems has created a demand for cryptographic proofs: systems to prove that a piece of data is a valid output for a given program. These systems exist, but face very high runtimes for the generation of proofs. Significant effort has been …

Optimizations for sampling-based motion planning algorithms
Sampling-basedalgorithms solve the motion planning problem by successively solving several separate suproblems of reduced complexity. As a result, the efficiency of the sampling-based algorithm depends on the complexity of each of the algorithms used to solve the individual subproblems, namely the …

Performance and Memory Space Optimizations for Embedded Systems
<p>Embedded systems have three common principles: real-time performance, low power consumption, and low price (limited hardware). Embedded computers use chip multiprocessors (CMPs) to meet these expectations. However, one of the major problems is lack of efficient software support for CMPs; in …

Automating runtime optimizations for parallel object-oriented programming
… programmability in parallel programs: automated optimizations and object-orientation. We have developed the parallel object-oriented language Charm++ (an extension of C++), which enables the benefits of object-orientation to be applied to the problems of parallel programming. In order to improve …

Target Design and Optimizations for Spent Fuel Transmutation
There are six long-lived fission products (LLFPs) identified in nuclear spent fuel, which account for at least 99% of the long-term radiotoxicity once actinide recycling is completed. This thesis examines the feasibility of using proton beams to transmute LLFPs into shorterlived or stable isotopes. …

Transmit simulation and receive optimizations for 802.11b networks
The simulation presented in this paper provides an implementation of a full simulated transmit chain from packet encoding through base band modulation for the 802.11b wireless networking standard. This forward transmit chain is coupled with a physical channel simulation that can introduce a number …
