Open Source Java Virtual Machine Software

A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR and combines with the Extensions for OpenJDK for OpenJ9 repo. We're not sure which route you might have taken on your way here, but we're really pleased to see you! If you came directly from our website, you've probably already learned a lot about Eclipse OpenJ9 and how it fits into the OpenJDK ecosystem. Eclipse OpenJ9 is an independent implementation of a Java Virtual Machine. "Independent implementation" means it was built using the Java Virtual Machine specification without using any code from any other Java Virtual Machine. The OpenJ9 JVM combines with the Java Class libraries from OpenJDK to create a complete JDK tuned for footprint, performance, and reliability that is well suited for cloud deployments. The original source contribution to OpenJ9 came from the IBM "J9" JVM which has been used in production by thousands of Java applications.

A PSP porting of SUN's phoneMEFeature (https://phoneme.dev.java.net/) project, to enable MIDP/JavaME applications running on PSP. You can also find phoneMEAdvanced PSP porting from another project: pspME(https://sourceforge.net/projects/pspme)

Jasmin is a Java Assembler. It takes ASCII descriptions for Java classes, written in a simple assembler-like syntax. It converts them into binary Java .class class files suitable for loading into a Java Virtual Machine implementation.

Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes.

The PHP script engine for Java. --- Run PHP applications within any J2EE server or servlet engine and/or connect script engines like PHP with Java or .NET back ends efficiently.

The Ja.NET project provides open source Java development tools (e.g. Java 5 JDK ) and runtimes for .NET. With the help of Ja.NET's open source software, you can leverage your Java investments on .NET.

Emulator of the ancient 8 bit microprocessor ISP-8A 500D/600D or more common "SC/MP" from National Semiconductor. The download contains all sources plus an executable Java Jar file to start right away. Some SC/MP hex dump examples are provided in directory "/etc" as well. The download also contains unit tests and some helping documentation (also in /etc). You may slow down the CPU operations, displaying the CPUs status register as LEDs, to watch the CPU working with its registers. The emulator also contains a VDU (video display unit) output / ASCII input simulation. There are some demos in /etc. And have a look to the NIBL / TINY BASIC interpreter in the TINYBASIC folder, most of the code is over 40 years old. Have fun, Theo Heinrichs

This is the first ever project that ports Android OS into an image that can be used to create Android virtual machines running on Openstack clouds with full virtualisation support. Currently we only support Android 4.4 Kitkat 64bit distribution. Instructons on how to create the image yourself: http://thisismyeye.blogspot.co.uk/2014/04/enabling-virtio-drivers-on-kernel-for.html This image is not perfect yet. Contributors are welcome! This work is done by Chathura Madhusanka Sarathchandra Magurawalage as a part of his research activities at Network Convergence Laboratory (NCL), University Of Essex Related Research Projects: *EU-funded FP7 Project MONICA (Mobile Cloud Computing: Networks, Services and Architecture). *EU-funded FP7 Project CLIMBER (Cross-Layer Investigation and Integration of Computing and Networking Aspects of Mobile Social Networks). *EU-funded FP7 Project EVANS (End-to-end Virtual Resource Management..)

Execute Java code like java.exe 1. support service to start/stop 2. support console command to execute java

The fast x86 PC emulator in 100% pure Java

X10 is a class-based, strongly-typed, garbage-collected, object-oriented language. To support concurrency and distribution, X10 uses the Asynchronous Partitioned Global Address Space programming model (APGAS). This model introduces two key concepts -- places and asynchronous tasks -- and a few mechanisms for coordination. With these, APGAS can express both regular and irregular parallelism, message-passing-style and active-message-style computations, fork-join and bulk-synchronous parallelism. Both its modern, type-safe sequential core and simple programming model for concurrency and distribution contribute to making X10 a high-productivity language in the HPC and Big Data spaces. User productivity is further enhanced by providing tools such as an Eclipse-based IDE (X10DT). Implementations of X10 are available for a wide variety of hardware and software platforms ranging from laptops, to commodity clusters, to supercomputers.

SquirrelJME is intended to be a Java ME 8 compatible environment for strange and many other devices. The source is written in pure Java and is licensed under the GNU GPLv3+.

Jasmin is an interpreter for the x86 assembly language with a full-featured development environment aimed for educational purposes.

Infinity saves time and money by providing users with a virtual infrastructure without the need to buy and manage dedicated hardware. The Infinity virtualization platform gives users centralized management of their virtual machines (VMs), but unlike traditional virtualization solutions, Hosts running VMs can be any computer. Computer workstations and servers which are running Windows, Mac, Linux, BSD, Unix or no OS at all can be used to host VMs alongside their current applications. VMs can be run locally on workstations or they can be run on other Hosts and accessed remotely with the click of a mouse. VMs can be cloned, shared and teleported between Hosts in seconds. Using infinity can be as simple as plugging in an Infinity server, running the Infinity server in a VM, or booting a USB drive with Infinity installed on it. Then boot other computers from the network to run what ever you need. Installation details at http://www.techsologic.com/installing-infinity.php
