Release Notes: Performance enhancements were implemented in the server task dispatcher. A bug was fixed in the JPPF resource adapter that caused class loading problems when deployed in OC4J and Sun AS. A minor display issue was fixed in the fractals explorer. Improvements were made to the image color scheme in the fractals explorer.
Release Notes: Tasks can now be canceled and restarted remotely, as well as configured to time out on a given date or after a given elapsed time. The Administration console was upgraded to handle the new task management features. A major leap in execution performance has been implemented. The JPPF JCA resource adapter now implements asynchronous tasks submission, removing any risk of J2EE transaction timeout. The JPPF Samples Pack brings a set of exciting applications of JPPF to real-life problems. A Mandelbrot fractals explorer and protein sequence alignment are included.
Release Notes: JPPF is now integrated with JMX, and uses it to provide administration and monitoring services. Monitoring capabilities have been extended to the nodes as well as to the executed tasks. The Administration console provides an extended view of the JPPF network. Critical issues were fixed that would cause a node to crash in specific conditions.
Release Notes: JPPF is now licensed under the terms of the Apache License, Version 2.0. Starting from JPPF 1.0 beta1, all releases will be licensed under these terms. Prior versions will remain under the terms of the LGPL. For the first time, JPPF integrates seamlessly with J2EE. The JPPF Resource Adapter provides J2EE application servers with access to native grid services. Numerous bugfixes were performed, especially with regards to the distributed class loading mechanism.
Release Notes: The demos and samples can now be run from a user interface, the demonstrations console. The nodes can now override the performance settings on the server side. Several critical bugs were fixed in the server. Parts of the code were refactored for enhanced clarity and extensibility.
Release Notes: A server connection pooling capability was added to the client, resulting in increased throughput and performance. A new demonstration and documentation section were added to illustrate that capability. Multiple bugs were fixed in the administration console, resulting in a greater usability of its charting capabilities. A new, lightweight distribution of the source code has been added to the JPPF release.
Release Notes: The communications and execution performance was increased by 10%. Numerous bugs were fixed in the server, increasing its stability and scalability. A bug that would cause the client to crash was fixed in the distributed class loader. The graphical administration console was upgraded to use Substance L&F 3.1 and JFreeChart 1.0.3.
Release Notes: New load-balancing and failover capabilities were added to the client, which can now connect to multiple servers. The administration console now monitors multiple servers at once. The classloading mechanism was improved to facilitate EJB invocations from a task. The build scripts can now generate single jar files for deployment of nodes and servers. A bug was fixed that prevented the screensaver node from executing tasks.
Release Notes: An issue was fixed in the adaptive scheduling algorithm, which caused the tasks to be executed by only one node at a time. The performance of the scheduling algorithm was improved, resulting in a smaller execution overhead. Minor localization issues were fixed in the administration tool.
Release Notes: This release supports multiple servers in a peer-to-peer topology, enabling it to scale to millions of nodes. Nodes can now be run as Windows services. Many performance enhancements were made, making this release faster and easier to use. Many bugfixes were made, resulting in greater robustness and reliability.
