About UniCluster Express

UniCluster Express 3.2 is open
source cluster management software that integrates best-of-breed open
source technologies to provide everything one needs to run technical
and advanced computing applications on a cluster.

Components

Cluster Express integrates components like Globus and Grid Engine into a single open source software tool:

• Installer:
  UniCluster Express 3.2 provides an integrated installer that delivers
  the complete set of cluster stack components in a single, easy process.
• Job Scheduling:
  UniCluster Express 3.2 includes job management via Grid Engine, a
  widely deployed open source scheduler that features powerful and
  configurable, policy-based resource allocation, and useful defaults out
  of the box.
• Monitoring: In addition to job monitoring
  via Grid Engine, UniCluster Express includes real-time system-level
  monitoring based on Ganglia, a scalable distributed monitoring system
  for efficiently collecting system-level information (such as CPU load
  averages, memory utilization, and I/O rates) from all machines
  comprising the cluster. Cluster Express also adds a Monitoring Console
  -- a GUI tool with remote WAN accessibility for integrated monitoring
  of job-level and system-level information on the cluster.
• Data Management:
  UniCluster Express provides integrated components for efficiently and
  reliably managing distributed data. UniCluster Express's data
  management tools include Globus GridFTP, a high-performance, secure,
  reliable data transfer protocol optimized for high-bandwidth wide-area
  networks, and Globus Reliable File Transfer (RFT), a Web service that
  reliably manages file transfers and tracks data transfer status.
• Security:
  UniCluster Express includes standards-based Globus Grid Security
  Infrastructure (GSI) based on mature, widely used open source security
  software such as OpenSSL. This security infrastructure is cleanly
  integrated with local cluster security (e.g. NIS) to protect your
  cluster, applications and data with robust yet easy to manage and use
  host and user security.
• Grid Services: UniCluster
  Express utilizes open source Globus software components for building
  robust, secure grid systems and applications. Proven in production and
  operating some of the largest clusters and grids on the planet, Globus
  is the framework for the UniCluster Express’ remote access and
  federation services and includes GridFTP, Reliable File Transfer (RFT),
  WS-GRAM, MyProxy and GSI-OpenSSH.

Why UniCluster Express?

UniCluster
Express is the open source alternative to traditional
proprietary/commercial cluster software. UniCluster Express goes beyond
the bounds of these traditional tools to provide integrated
installation of multiple components, monitoring and analytics
capabilities, and support available both through Grid.org and Univa UD.
