1. Estudo exploratório sobre fontes de os jitter no kernel linux
The OS Jitter phenomenon has been considered an important factor in high-performance distributed computing. In this thesis, we present the results of an experimental study that quantifies the effects of different sources of OS Jitter in the Linux operating system. We use the DOE method to conduct controlled experiments statistically planned. Differently than

2. Distributed memory organization with support for data migration for noc-based MPSOCS / Distributed memory organization with support for data migration for noc-based MPSOCS
The evolution in the deployment of semiconductor technology has enabled the development of System-on-Chip (SoCs) that integrate several processing elements (PEs) and memory modules in a single chip. SoCs that integrate several PEs are referred as Multiprocessor System-on-Chip (MPSoCs). As the number of PEs increases in an MPSoC, techniques that present low e

3. Um modelo de memória transacional para arquiteturas heterogêneas baseado em software Cache / A transactional memory model for heterogeneous architectures based in Software Cache
The adoption of multi-core processors by the industry has pushed towards the development of new techniques to simplify programming parallel software. The technique called transactional memories is one of the most promising. This technique is able to execute multiple tasks concurrently in an optimistic way to achieve a better performance. Another advantage is

4. A progressive vector map browser for the web
With the increasing popularity of web-based map browsers, remotely obtaining a high quality depiction of cartographic information has become commonplace. Most web mapping systems, however, rely on high-capacity servers transmitting pre-rendered tiled maps in raster format. That approach is capable of producing good quality renderings on the client side while

5. Desempenho em ambiente Web considerando diferenciação de serviços (QoS) em cache, rede e servidor: modelagem e simulação / Performance in Web environments with differentiation of service (QoS) in caches, network and server: modeling and simutation
This PhD thesis presents the investigation of alternatives to improve the performance of Web environments by evaluating the impact of using differentiated service mechanisms in all points of the system. Several scenarios were created and modeled in the OPNET Modeler, with different configurations of both differentiated services and network overloading. A spe

7. Uma proposta para o gerenciamento de cache de um sistema de integraÃÃo de dados
Data Integration Systems (DIS) provide to the user an unified view of data stored in many different data sources. Those data sources are independent and each one has a particular schema elaborated to attend its userâs needs. Each DIS has a group of different data sources related to a specific domain and must obtain from each one the necessary data to answer

11. Um mecanismo integrado de cache e prefetching para sistemas de entrada e saída de alto desempenho.
An integrated caching and prefetching mechanism for a parallel network file system has the potential to improve both the speed and performance of I/O operations. Different cache policies and algorithms can be used in the system. Different prefetching mechanisms can also be used in the system. The performance of the I/O operations can also be influenced by ot
