Components

Eclipse OMR is made up of shared, reusable, open-source core components for building language runtimes. These components include:

Garbage Collector (GC): a garbage collection framework for managed heaps. Eclipse OMR includes several implementations: mark-and-sweep, generational, and parallel scavenger.
Port Library (port): a platform abstraction (porting) library.
Thread Library (thread): a cross platform threading library.
Utility Library (util): a variety of utility libraries that provide functions for building cross platform runtimes.
Virtual Machine (VM): APIs to manage per-interpreter and per-thread contexts.
Trace Library (omrtrace): a tracing library for communication with IBM Health Center monitoring tools.
Signal Handling Compatibility Library (omrsigcompat): a signal handling compatibility library.
Compiler: for native code generation.
Diagnostic services: (to be contributed) Health Center provides a live view of runtime details, such as GC statistics and method profiling.
