Dynamic path profile aided recompilation in a JAVA just-in-time compiler

Just-in-Time (JIT) compilers for Java can be augmented by making use of runtime profile information to produce better quality code and hence achieve higher performance. In a JIT compilation environment, the profile information obtained can be readily exploited in the same run to aid recompilation and optimization of frequently executed (hot) methods. This paper discusses a low overhead path profiling scheme for dynamically profiling AT produced native code. The profile information is used in recompilation during a subsequent invocation of the hot method. During recompilation tree regions along the hot paths are enlarged and instruction scheduling at the superblock level is performed. We have used the open source LaTTe AT compiler framework for our implementation. Our results on a SPARC platform for SPEC JVM98 benchmarks indicate that (i) there is a significant reduction in the number of tree regions along the hot paths, and (ii) profile aided recompilation in LaTTe achieves performance comparable to that of adaptive LaTTe in spite of retranslation and profiling overheads.

La producción flexible: Just in time versus organización científica del trabajo

Nadie puede negar que la competitividad actual de la industria japonesa se basa, entre otras razones, en el bajo coste y alto nivel de calidad de sus productos. Ambas cualidades se han conseguido por la aplicación, a partir de los 70, de prácticas innovadoras y nuevas tecnologías de fabricación como es el caso del Just in Time.

Thomas Heywood: just in time

The scholarly study of the dramatic works and career of Thomas Heywood has increased significantly in the last fifty years but still lags far behind that of his contemporaries Shakespeare and Jonson. Labelled the ‘prose Shakespeare’ by Charles Lamb in the early nineteenth century, Heywood seems to have been considered by scholars and publishers to be a ghostly figure who haunted the early modern theatrical world. In fact, recent research using archival records shows the ways in which Heywood is at the centre of an extensive and highly networked professional industry.

Bringing Japanese manufacturing systems to America: the feasibility of implementing just-in-time production in the United States

This paper addresses the feasibility of implementing Japanese manufacturing systems in the United States. The recent success of Japanese transplant companies suggests that Just-In-Time (JIT) production is possible within America's industrial environment. Once American workers receive proper training, they have little difficulty participating in rapid setup procedures and utilizing the kanban system. Japanese transplants are gradually developing Japanese-style relationships with their American supplier companies by initiating long-term, mutually beneficial agreements. They are also finding ways to cope with America's problem of distance, which is steadily decreasing as an obstacle to JIT delivery. American companies, however, encounter Significant problems in trying to convert traditionally organized, factories to the JIT system. This paper demonstrates that it is both feasible and beneficial for American manufacturers to implement JIT production techniques. Many of the difficulties manufacturers experience center around a general lack of information about JIT. Once a company realizes its potential for setup-time reduction, a prerequisite for the JIT system, workers and managers can work together to create a new process for handling equipment changeover. Significant results are possible with minimal investment. Also, supervisors often do not realize that the JIT method of ordering goods from suppliers is compatible with current systems. This "kanban system" not only enhances current systems but also reduces the amount of paperwork and scheduling involved. When arranging JlT delivery of supplier goods, American manufacturers tend to overlook important aspects of JIT supplier management. However, by making long-tenn commitments, initiating the open exchange of information, assisting suppliers in reaching new standards of performance, increasing the level of conununication, and relying more on suppliers' engineering capabilities, even American manufacturers can develop Japanese-style supplier relationships that enhance the effectiveness of the system.

Using Just-in-Time Data to Intervene with At-Risk Students

With increasing state and federal policy pressure to increase retention and graduation rates, academic affairs leaders seek metrics to track that predict student success. This report analyzes behavioral, academic, and financial indicators of student risk and suggests actions administrators can take to intervene with students who cross risk thresholds.

Contabilidade gerencial como apoio ao "just in time"

Descreve as técnicas da filosofia "Just in Time" e apresenta as modificações necessárias aos Sistemas Gerencias para que se tornem coerentes com a filosofia JIT, bem como meçam adequadamente a melhoria contínua da Empresa. Critica tanto o Custeio' Direto como o Custeio por Absorção, apresentando como alternativa o Custeio "ABC". Mostra como o JIT facilita o Custeio dos Produtos e destaca os aspectos estratégicos da Avaliação de Desempenho. Finalmente discorre sobre um estudo de caso apresentando propostas de melhoria

Possibilidades de aplicação do sistema Just-in-time junto a fornecedores

Trata-se de um estudo Teórico-Empírico sobre a filosofia gerencial Just-in-Time em seu aspecto de relacionamento com fornecedores de empresas industriais. Aborda ainda os principais fatores que limitam a aplicação da respectiva filosofia, tornando nossas empresas vulneráveis à concorrência internacional

Um estudo sobre o sistema just in time de produção

A proposta deste trabalho é apresentar a tecnologia de administração da produção desenvolvida pelos japoneses após a Segunda Guerra Mundial, de maneira que a essência do sistema seja mostrada através de conceitos de produção, cuja aplicabilidade é universal. A maneira encontrada para cumprir esse objetivo foi selecionar os principais conceitos e técnicas de produção e mostrar como elas compõem um conjunto bastante interdependente entre si e altamente dependente da participação do pessoal de fábrica. A esse conjunto de técnicas e conceitos de produção desenvolvidos pelos japoneses daremos o nome de "Sistema Just in Time de Produção".
