Recent results on the static single assignment (SSA) form open promising directions for the design of new register allocation heuristics for just-in-time (JIT) compilation. In particular, heuristics based on tree scans with two decoupled phases, one for spilling, one for splitting/coloring/coalescing, seem good candidates for designing memory-friendly, fast, and competitive register allocators....

Just-in-time compilation has proven an effective, though effort-intensive, choice for realizing performant language runtimes. Recently introduced JIT compilation frameworks advocate applying meta-compilation techniques such as partial evaluation or meta-tracing on simple interpreters to reduce the implementation effort. However, such frameworks are few and far between. Designed and highly optim...

Modern Just-in-Time compilers (or JITs) typically interleave several mechanisms to execute a program. For faster startup times and observe the initial behavior of an execution, interpretation can be initially used. But after while, JITs dynamically produce native code for parts program they often. Although some time is spent compiling dynamically, this mechanism makes much remaining execution. ...

Modern Java Virtual Machines (JVM) for desktop and server computers use just-in-time (JIT) compilation to increase their performance. For embedded Java processors, JIT usually is not feasable. Therefore the java bytecode needs to be optimized for a specific platform ahead-of-time. To generate optimized bytecode for the JOP Java processor several existing tools were compared. In order to impleme...

A medium sized UK based academic publishers own a subsidiary printing business. Presently the Academic Printers (AP) is experiencing productions line flow problems reducing the efficiency of the operation. Most of the problems are generated by the imbalanced workflow through the system. By implementing a JIT production planning system it is hoped that some of the production problems can be reso...

This paper presents the requirements for just in time knowledge management (JIT-KM). In order to deliver high-value information to user for decision-making, one must understand the user’s preferences, biases and decision context. A JIT-KM architecture is presented consisting of user, middleware and data services to search for information from heterogeneous sources, and to rank and deliver this ...

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...
