Java-Centric Grid Computing: Ibis 1.0 Released
rvannieuwpoort writes "Ibis 1.0 has been released. Ibis is a flexible and efficient Java-based programming environment for Grid computing. Ibis improves Java's serialization and RMI performance up to a factor of 10. It also extends Java with a range of communication paradigms, including group communication, divide-and-conquer and collective communication. An additional nice feature of Ibis is that it can communicate through firewalls, without opening ports, using TCP. Ibis is free software (BSD-style license). It runs on any platform that has a Java 1.4 or higher JVM."
No, Sun has its own grid computing product that I'm sure it would rather support.
