В среду, 22 октября, в Санкт-Петербурге в гостинице Park Inn Пулковская пройдёт встреча JUG с Маркусом Лагергеном, в прошлом одним из основателей и ведущим разработчиком JRockit JVM, а нынче — ведущим разработчиком HotSpot JVM. Маркус расскажет о внутреннем устройстве виртуальной машины JRockit.

The JRockit JVM was originally developed by Appeal Virtual Machines as a from scratch server-side JVM in order to compete with HotSpot from Sun Microsystems. Appeal Virtual Machines was acquired by BEA Systems in 2002, which in turn became part of Oracle in 2010. JRockit is battle proven in the commercial space as a high performance server JVM and has unique monitoring and manageability capabilities for doing zero overhead instrumentation of production systems.

This talk covers the design rationales that the JRockit architects did in code generation, memory management, synchronization and serviceability. The JRockit and HotSpot JVMs are currently in the process of being merged into one code base, most of which will be part of the OpenJDK.

 

Доклад будет на английском языке. Участие бесплатное. Необходима регистрация.

One of the founding members of Appeal Virtual Machines, the company that developed the JRockit JVM, bought by BEA Systems in 2002. Team lead and architect for the JRockit code generators; he has been involved in pretty much every other aspect of JVMs over the years. Between 2007 and 2010, worked for Oracle on fast Virtualization technology. As of September 2011, he is a member of the Oracle Java language team, investigating dynamic languages on the JVM and general runtime futurist.

Co-author of the book “Oracle JRockit – the definitive guide“, which, despite the product centric title, has been praised as the best book ever written on JVM internals.
