Graal VM: Multi-Language Execution Platform
2 likes3,349 views
The document discusses the development of GraalVM, a new JIT compiler designed for multi-language performance on the JVM, facilitating the execution of languages that resemble Java or C#. It outlines the challenges faced regarding performance, implementation of various components such as garbage collection, and the integration of different programming languages including Java, JavaScript, and Ruby. Additionally, it emphasizes the importance of performance metrics and language interoperability, with resources provided for further exploration.
