JPPF is a an open source grid computing solution that makes it easy to parallelize CPU-intensive applications.

What's new in JPPF 2.4

Executor service batch modes

The executor service facade to JPPF now enables the grouping of tasks submitted individually, according to space (number of tasks) or time (via timeout settings).
Tasks submitted individually are grouped into JPPF jobs and thus benefit from full parallelism and a significant throughput increase.

New "node life cycle" extension point

It is now possible to subscribe to node life cycle events, and perform actions accordingly.

New "Node Life Cycle" sample

The "Node Life Cycle" sample was added to the JPPF samples pack, illustrating how transaction management can be controlled via node life cycle events.

Performance, memory footprint enhancements

Disk overflow capabilities were added to the nodes and clients.
Reworked I/O processing results in faster network I/O and smaller memory footprint.

Documentation

A new JPPF overview chapter was added.
The online documentation was reorganized for an easier navigation experience.
