Open Source Java Clustering Software

MyCAT is an Open-Source software, “a large database cluster” oriented to enterprises. MyCAT is an enforced database which is a replacement for MySQL and supports transaction and ACID. Regarded as MySQL cluster of enterprise database, MyCAT can take the place of expensive Oracle cluster. MyCAT is also a new type of database, which seems like a SQL Server integrated with the memory cache technology, NoSQL technology and HDFS big data. And as a new modern enterprise database product, MyCAT is combined with the traditional database and new distributed data warehouse. In a word, MyCAT is a fresh new middleware of database. MyCAT ’s objective is to smoothly migrate the current stand-alone database and applications to cloud side with low cost and to solve the bottleneck problem caused by the rapid growth of data storage and business scale.

JPPF makes it easy to parallelize computationally intensive tasks and execute them on a Grid.

Reliable group communication based on IP multicast and configurable protocol stack

openQRM is a web-based open source datacenter management and hybrid cloud computing platform that integrates flexibly with existing components in enterprise data centers. Releases available at https://github.com/openQRM/openqrm-community. Please visit http://www.openqrm-enterprise.com for latest 5.3 free Community Release. Includes important security updates, bugfixes and enhancements especially for KVM and Cloud plugin. openQRM abstracts Virtualization and supports the following virtualization technologies: KVM, XEN, Citrix XenServer, VMWare ESX & LXC. The Hybrid Cloud Connector in openQRM supports a range of private or public cloud providers to extend your infrastructure on demand via Amazon AWS, Eucalyptus or OpenStack. openQRM automates provisioning, virtualization, storage and configuration management, and it takes care of high-availability.

GridSim allows modeling and simulation of entities in parallel and distributed computing systems such as users, applications, resources, and resource brokers/schedulers for design and evaluation of scheduling algorithms. http://www.gridbus.org/gridsim

The Community Scheduler Framework (CSF) is a set of Grid Services, implemented using the Globus Toolkit, which provides an environment for the development of metaschedulers that can dispatch jobs to resource managers such as LSF, SGE, PBS and Condor.

Ridiculously simple, Prevayler provides transparent ACID persistence and replication for plain old Java objects. It is literally several thousand times faster than using a relational database through JDBC.

Scarlet is an extension for Atlassian JIRA, the leading Enterprise issue tracking and management software, allowing easy clustering of JIRA application instances, ensuring both high availability and linear scalability.

Generic clustering/load-balancing platform (over a LAN or internet) using java based P2P Aorta workers that execute java "tasklets". Various tasklets can be implemented to solve fractals, process images, render webpages, crack RSA "brute force".

Need extra computing power? Use other people's computers! Rent out your computer when you are not using it! Aspen provides secure, fault-tolerant, platform-independent micropayment-based distributed computing.

the bbsc - BinBase Cluster System is a specification for the distributed calculation of jobs using j2ee and a cluster. We provide an implementation for Rocks Linux Cluster (Sun Grid Engine). This project has been merged into the BinBase system a couple of years back.

BioCluster is a peer-to-peer clustering platform for Asterisk, the Open Source PBX, which allows utilising Asterisk as a full carrier-grade telephony solution.

OpenBAM is a Business Activity Monitoring(BAM) application for Operations Managers in service organizations who are constantly trying to figure out what's effecting their business by trying to co-relate data from multiple systems.

A set of tools for working with J2EE application servers. it includes a generic JDBC datasource implementation, and a jndi/rmi/iiop multiplexer for accessing remote application servers through a standalone web container

See http://www.cubrid.org/cluster. CUBRID Cluster is an open source clustered DBMS for high scalability including global schema, distributed partition and load balancing features. It is a spin-off project from CUBRID project and supported by NHN.

Chordless is a Chord and DHash implementation written in java. It implements almost everything from Chord and DHash described at http://pdos.csail.mit.edu/chord/, as well as some extra features such as transactions and remote method invocation.

Circus is a jMonkeyEngine based cluster-solution for multi-screen VR-systems.

Xnet is a Cluster Monitoring Tool written in java for openMosix.It has a graphical representation of all ongoing processes like Number of nodes,various process running on the nodes,cpu usage and network usage.

The Orchestrator server is responsible for distribution and launch of simple apply/rollback shell scripts in a particular order across multiple servers . If for any reason deployment is failing at a particular stage the process will stop and you can rollback any changes done until then. In case you want to deploy your code or just call your preferred DSC client to apply the configuration locally the Orchestrator can be a handy tool. The operation can be started manually or scheduled, depending on your needs. In terms of audit and trace capabilities, the system is collecting all console output of your shell scripts from all servers and saves the logs centrally for review.

Cluster101 allows you to run software on many hosts and perform a simple task scheduling. No need to install any software on the hosts (it just runs tasks via ssh). It is typically used for running scientific applications on University campuses.

Alternative implementation of Spring framework remoting subsystem that supports different schemes of remote communication between client and server (1-1, 1-many, dynamic services discovering).
