A performance study of multithreading

Creator:: Kwak, Hantak
Abstract:: As the performance gap between processor and memory grows, memory latency will be a major bottleneck in achieving high processor utilization. Multithreading has emerged as one of the most promising and exciting techniques used to tolerate memory latency by exploiting thread-level parallelism. The question however remains as to how effective...

Similarity-based real-time concurrency control protocols

Creator:: Lai, Chih
Abstract:: Serializability is unnecessarily strict for real-time systems because most transactions in such systems occur periodically and changes among data values over a few consecutive periods are often insignificant. Hence, data values produced within a short interval can be treated as if they are "similar" and interchangeable. This notion of similarity...

On resource placements and fault-tolerant broadcasting in toroidal networks

Creator:: AlMohammad, Bader Fahed AlBedaiwi
Abstract:: Parallel computers are classified into: Multiprocessors, and multicomputers. A multiprocessor system usually has a shared memory through which its processors can communicate. On the other hand, the processors of a multicomputer system communicate by message passing through an interconnection network. A widely used class of interconnection networks is the toroidal...

Resource placement, data rearrangement, and Hamiltonian cycles in torus networks

Creator:: Bae, Myung Mun
Abstract:: Many parallel machines, both commercial and experimental, have been/are being designed with toroidal interconnection networks. For a given number of nodes, the torus has a relatively larger diameter, but better cost/performance tradeoffs, such as higher channel bandwidth, and lower node degree, when compared to the hypercube. Thus, the torus is...

High-performance data-parallel input/output

Creator:: Moore, Jason Andrew
Abstract:: Existing parallel file systems are proving inadequate in two important arenas: programmability and performance. Both of these inadequacies can largely be traced to the fact that nearly all parallel file systems evolved from Unix and rely on a Unix-oriented, single-stream, block-at-a-time approach to file I/O. This one-size-fits-all approach to parallel...

Data decomposition and load balancing for networked data-parallel processing

Creator:: Crandall, Phyllis E.
Resource Type:: Dissertation

Scheduling non-uniform parallel loops on MIMD computers

Creator:: Liu, Jie
Abstract:: Parallel loops are one of the main sources of parallelism in scientific applications, and many parallel loops do not have a uniform iteration execution time. To achieve good performance for such applications on a parallel computer, iterations of a parallel loop have to be assigned to processors in such a...

Resource Type:: Dissertation

Cluster partitioning approaches to parallel Monte Carlo simulation on multiprocessors

Creator:: Ranawake, Udaya A.
Abstract:: We consider the parallelization of Monte Carlo algorithms for analyzing numerical models of charge transport used in semiconductor device physics. Parallel algorithms for the standard k-space Monte Carlo simulation of a three band model of bulk GaAs on hypercube multicomputers are first presented. This Monte Carlo model includes scattering due...
