The project aimed to create a circuit simulator that produces JIT compiled native code through LLVM’s APIs. A JIT based simulation approach provides native simulation speed, while still allowing native code to be recompiled to provide circuit debugging features unavailable in statically compiled simulators. The result of the project is a simulator that performs competitively against existing si...

attempts to link complex data types such as CAD drawings with traditional EDI documents, on-line catalogues and various Internet marketing initiatives. Many authors have suggested a pivotal role for Electronic Commerce (EC) technologies in the implementation of Just-In-Time (JIT) replenishment systems. To clarify the relationship between EC adoption and JIT implementation, case studies were con...

This paper is based on an empirical study of the relationship between Just-inTime (JIT) production, automation, cost allocation practices and the relative use of cost information for making and evaluating managerial decisions. The study uses a survey questionnaire to collect data from a random sample of New Zealandbased manufacturing organizations. Hypotheses were tested using bivariate tests a...

In the past few years billions of user passwords have been exposed to the threat of offline cracking attempts. Such brute-force cracking attempts are increasingly dangerous as password cracking hardware continues to improve and as users continue to select low entropy passwords. Key-stretching techniques such as hash iteration and memory hard functions can help to mitigate the risk, but increase...

Tracing JIT compilation generates units of compilation that are easy to analyse and are known to execute frequently. The AJITPar project aims to investigate whether the information in JIT traces can be used to make better scheduling decisions or perform code transformations to adapt the code for a specific parallel architecture. To achieve this goal, a cost model must be developed to estimate t...

We present the design and implementation of several optimizations and techniques included in the latest IBM Java Just-in-Time (JIT) Compiler. We first discuss some of the modifications we have applied to Sun Microsystems’ reference implementation of the Java Virtual Machine (JVM) Specification to increase the performance, including a change in the object layout. We then describe each of the opt...

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 pro...

This paper addresses the problem of how a group of agents cooperating on a complex plan with interdependent actions can coordinate their scheduling and execution of those actions, particularly in domains where actions may fail or have uncertain durations. If actions fail (or fail to meet their deadlines), the repercussions for the rest of the team’s plan can be dramatic. This paper presents a p...

Method inlining is one of the most important optimizations for JIT compilers in Java virtual machines. In order to increase the number of inlining opportunities, a type analysis can be used to identify monomorphic virtual calls. In a JIT environment, the compiler and type analysis must also handle dynamic class loading properly because class loading can invalidate previous analysis results and ...

Microsoft’s Rotor is a shared-source CLI implementation intended for use as a research platform. It is particularly attractive for research because of its complete implementation and extensive libraries, and because its modular design allows different implementations of certain components (e.g., just-in-time compilers). Our group has independently developed a highperformance just-in-time (JIT) ...
