On the TeraGrid, what is iRODS?
Note: After ten years of service to the national science and engineering community, the TeraGrid project has ended. It is succeeded by a new National Science Foundation (NSF) program, the Extreme Science and Engineering Discovery Environment (XSEDE). You should move any data stored on TeraGrid systems to an alternate storage resource. If you have leftover service units on your TeraGrid allocation, or if your research requires further use of high performance computational, visualization, storage, and network resources, consider applying for an allocation on one or more XSEDE digital services.
Under development at San Diego Supercomputer Center, iRODS (integrated Rule-Oriented Data System) is a new data grid software system based on expertise gained through the application of Storage Resource Broker (SRB) technology in support of data grids, digital libraries, persistent archives, and real-time data systems.
Major features of the iRODS architecture include:
- Data grid architecture based on a client/server model and
distributed storage and compute resources
- A database system for maintaining the attributes and states of
data and operations
- A rule system for enforcing and executing adaptive rules
At the core of the iRODS rule system is the iRODS Rule Engine, which interprets system-level rules to decide how to respond to various requests and conditions. iRODS is open source under a BSD-type license.
