The Barcelona Project

Note: This page refers to a project that is no longer active. However, we keep working on some of the activities we started in the Barcelona project; for more information look here or contact Grzegorz Czajkowski, the Principal Investigator of the Barcelona project.

The Barcelona project is investigating virtual machine architectures to improve the scalability, reliability, and availability of the Java^TM platform. The main design dimension is transparent sharing of meta-data among computations. We are also working on enhancing the Java platform to make it a complete operating environment. This includes extending the platform with interfaces for application isolation and resource management.
