Open Source Virtual Machine Software

How can we easily develop applications for multicore or multicomputer architectures? We frequently use middlewares for that problem, but they are often complex and less productive. This way, at DECOM-UFOP, we have a middleware, named JavaCa&La or just JCL, to build portable and scalable solutions over many high performance computer architectures. Our middleware APIs is simple, intuitive and designed for young and senior programmers who don’t have high performance programming skills. Using our middleware, different programmers can develop applications in a collaborative way, i.e., one programmer application can read and write global variables from another application, developed by another programmer, in another machine, without explicit references. Existing Java applications can be executed by JCL. Low refactorings to insert distributed JCL maps in your existing code. Portable JCL code for multicore and multicomputer architectures.

Py4J enables Python programs to dynamically access arbitrary Java objects. Methods are called as if the Java objects resided in the Python virtual machine. There is no code to generate and no interface to implement for shared objects on both sides.
