JIT-Compiler-Assisted Distributed Java Virtual Machine

There is now a strong interest in high-performance execution of multithreaded Java programs in a cluster. Previous efforts to provide for such executions have either used static compilation tools that can transform multithreaded Java programs into parallel versions, or interpreter-based cluster-aware JVMs that offer the needed support. They failed however to be fully compliant with the Java lan...

Efficient Code Caching for an Embedded Dynamic Adaptive Compiler

OpenJIT—A Reflective Java JIT Compiler

The so-called ‘Open Compilers’ is a technique to incorporate various self-descriptive modules for language customization and optimization based on computational reflection. We apply the open compiler technique to a Java Just-In-Time compiler to develop the OpenJIT compiler, which allows class-specific customization and optimization, fostering research of new compilation techniques such as appli...

pylibjit: A JIT Compiler Library for Python

We present pylibjit, a Python library for generating machine code at load time or run time. The library can be used for dynamic code generation, although it is mainly aimed at optimizing compilation of existing Python function definitions. Python functions can be compiled by simply annotating them with a decorator specifying data types. The pylibjit compiler takes advantage of this type informa...

A Retargetable JIT Compiler for Java

Interpreted Java has poor performance. Therefore most Java Virtual Machines (JVM) contain a just-in-time compiler (JIT) that compiles the bytecode to the processor’s native instruction set. Most of these compilers are written in C and tightly integrated with the JVM. We describe a JIT compiler that is written in Java and retargetable to a different JVMs and CPUs.
