Java programs are deployed in a bytecode format that is executed by a Java virtual machine (JVM). JVM performance is determined by several major components: execution engine, garbage collector, and threading system. The static compilation and optimization approach, such as…

O objetivo desta publicação é apresentar a implementação Java do algoritmo de Marr e Hildreth (Marr & Hildreth, 1980) para a detecção de bordas. O objetivo maior das implementações é a construção de uma biblioteca de processamento de imagens em…

In designing compiler analyses and optimisations, the choice of intermediate representation (IR) is a crucial one. Static Single Assignment (SSA) form in particular is an IR with interesting properties, enabling certain analyses and optimisations to be more easily implemented while…

In this article we present a performance comparison of four symmetric block ciphers namely DES, Triple-DES, AES, and Blowfish. Performance evaluation based on CPU execution time is conducted under WinXP and Ubuntu /Linux version 8.10 operating system platforms. The study…

Java for high performance and distributed computing.

Abstract

The Java language first came to public attention in 1995; very soon after it was being speculated that Java may…

Side-effect analysis gives information about the set of locations that a statement may read or modify. This analysis can provide information useful in a compiler for performing aggressive optimizations. The impact of the use of side-effect analysis in compiler optimizations…

A fundamental problem in interprocedural program analyses is the need to represent and manipulate collections of large sets. Binary Decision Diagrams (BDDs) are a data structure widely used in model checking to compactly encode large state sets. In this dissertation,…

With the development of multi-processors, multi-threaded programs and programming languages have become more and more popular. This requires extending the scope of program analysis and compiler optimization from traditional, sequential programs to concurrent programs., Naumovich et al. proposed May Happen…
