Although a Thor processing cluster can be implemented and used without a Roxie cluster, an HPCC environment which includes a Roxie cluster should also include a Thor cluster. Roxie utilizes a distributed indexed filesystem percormance provide parallel processing of queries using an optimized execution environment and filesystem for high-performance online processing.

The HPCC platform incorporates a pdff architecture implemented on commodity computing clusters to provide high-performance, data-parallel processing for applications utilizing big data. Both Thor and Roxie clusters utilize the ECL programming language for implementing applications, increasing continuity and programmer productivity. The first of these platforms is called a data refinery whose overall purpose is the general processing of massive volumes of raw data of any type for any purpose but typically used for data cleansing and hygiene, extract, transform, load downllad of the raw data, record linking and entity resolution, large-scale ad-hoc complex analytics, and creation of keyed data and indexes to support high-performance structured queries and data warehouse applications.

The HPCC system architecture includes two distinct cluster processing environments, each of dlwnload can be optimized independently for its parallel data processing purpose.

High Performance Cluster Computing

A Roxie cluster includes multiple nodes with server and worker processes for processing queries; an additional auxiliary component called an ESP server which provides interfaces for external client access to the cluster; and additional common components which are shared with a Thor cluster in an HPCC environment. By using this site, you agree to the Terms of Use and Privacy Policy. The HPCC software architecture incorporates the Thor and Roxie clusters as well as common pvf components, an external communications layer, client interfaces which odwnload both end-user services and system management tools, and auxiliary components to support monitoring and to facilitate loading and storing of filesystem data from external sources.

A Thor cluster is similar in its function, execution environment, filesystem, and capabilities to the Google and Hadoop MapReduce performamce. It is an alternative to Hadoop. Retrieved from ” https: The Thor cluster is used to build the distributed index files used by the Roxie cluster and to develop online queries which will be deployed with the index files to the Roxie cluster.

This page was last edited on 27 Octoberat The data refinery is also referred to as Thora reference to the mythical Norse god of thunder with the large hammer symbolic of crushing large amounts of raw data into useful information.

The second of the parallel data processing platforms is called Roxie and functions as a rapid data delivery engine.

High Performance Cluster Computing: Programming and Applications

A Roxie cluster is similar in its function and capabilities to Hadoop with HBase and Hive capabilities added, and provides for near real time predictable query latencies. In addition to the Thor master and slave nodes, additional auxiliary and common components are needed to implement a complete HPCC processing environment.
