DevelopmentJPPF, the Java Parallel Processing Framework The Java Parallel Processing Framework (JPPF) is a cross-platform GPL-licensed tool set for controlling the execution of CPU-intensive tasks across multiple execution nodes. JPPF is intended to be used in the scientific data processing field.
Java Parallel Processing Framework is a set of tools and APIs to facilitate the parallelization of CPU intensive applications, and distribute their execution over a network of heterogenous nodes.
It is intended to run in clusters and grids.
A brief feature list of JPPF includes:
The initial JPPF beta release, version 0.6.0, has been announced. "This release is the first beta version of the Java Parallel Processing Framework. From now on, all the work will be dedicated to testing, bug fixing, and documentation fixing, until it is deemed "stable". There will be intermediate beta, then release candidate, release, so don't lose hope." The release features a complete user guide, a new matrix multiplication example, bug fixes and documentation improvements. JPPF is available for download here. Dependencies include version 5 of the Java 2, Standard Edition (J2SE) and Apache Ant 1.6.2 or newer. See the readme document for installation details.

ZODB 3.2.10 final released Version 3.2.10 final of ZODB, the Zope Object Database, is out. "ZODB 3.2.10 contains a few bugfixes relative to 3.2.9, all in obscure error cases. The most serious is a workaround for what appears to be a rare race bug in Microsoft's implementation of socket binding on Windows platforms."
ZODB 3.4.2 final released Version 3.4.2 final of ZODB, the Zope Object Database, is out. "ZODB 3.4.2 mostly contains obscure error-case bugfixes relative to 3.4.1. One important fix: most applications that do subtransaction commits do so to reduce RAM consumed by the ZODB memory ("pickle") cache. When subtransactions were reimplemented on top of savepoints, this cache reduction no longer occurred. That was an oversight, and is repaired in 3.4.2."
