The Java programming language and the underlying virtual machine model have introduced new complexities for compilation. Various approaches ranging from just in time (JIT) compilation to ahead of time (AOT) compilation are being explored with the aim of improving the performance of Java programs. The hurdles facing the achievement of high performance in Java and the strengths and weaknesses of ...

The focus on the sequential nature of the improvement initiatives has neglected the synergistic effects among practices and literature lacks research on complementarity between internal and external bundles of practices. The aim of this paper is to test the existence of complementarity among internal and external just-in-time bundles. We run statistical analysis using the third round of High Pe...

We introduce straf, a Scala framework for recording and optimizing execution traces of an interpreter it is composed with. For interpreters that satisfy the requirements detailed in this paper, this composition requires but a small effort from the implementer to result in a trace-based JIT compiler. We describe the framework, and illustrate its composition with a Scheme interpreter that satisfi...

This paper argues the widespread adoption of Just-in-Time (JIT) logistics provides a key to understanding the growth in the U.S. trade share. To do so, I develop a dynamic trade model based on the choice of the logistics technology used in a firm’s supply chain. The model’s predicted trade dynamics depend on how the set of firms using JIT with international suppliers changes over time. A numeri...

Many studies have shown that the careful planning of construction logistics can result in significant saving. However, despite attempts to improve the logistics of construction materials, the purchase, delivery, storage and movement of materials are still conducted in a rather unstructured manner. In this paper, construction logistics are modeled and analyzed using Petri Net (PN) techniques. Th...

For virtual machine implementations to achieve high performance, some form of translation of the virtual machine's input language into the native code of the host machine seems necessary. This translation process is often called justin-time (a.k.a. JIT) compilation, or sometimes dynamic compilation. The use of JIT compilation introduces a tension in virtual machine design: compilation time adds...

In widely-used actor-based programming languages, such as Erlang, sequential execution performance is as important as scalability of concurrency. In order to improve sequential performance of Erlang, we develop Pyrlang, an Erlang virtual machine with a just-in-time (JIT) compiler by applying an existing meta-tracing JIT compiler. In this paper, we overview our implementation and present the opt...
