Da Vinci Machine Project Wiki

The Da Vinci Machine Project is a set of modifications of the JVM to support implementations of non-Java languages at a quality level (performance, compactness) near that of Java. The project is a part of the OpenJDK. Developers can write notes here.

Who writes this wiki?

• We are using the Community Write pattern.
• There is no public write access, except for leaving page comments. You must be registered and logged in to leave comments.
• Please do add page comments when a page should answer your question but doesn't. (That means, potentially on any page.)
• The most effective page comments will include links to relevant email discussion threads, e.g., on the OpenJDK mlvm-dev list.
• Any member of the OpenJDK Hotspot Group or a related group should feel free to contribute.
• Committers, contributors, and users of the Da Vinci Machine Project code base are welcome to contribute.
• Write permissions are not automatic until and unless the DBs (Sun wiki vs. OpenJDK) get on speaking terms. If you think you should have write permission and don't ask jrose.
