gLite Worker Node - SL5 x86_64 platform


The gLite Standard Worker Node is a set of clients required to run jobs sent by the gLite Computing Element via the Local Resource Management System.

For a quick overview on the WN, please check the WN service reference card.

The gLite WN now includes the SWAT packages. SWAT (Site Wide Area Testing) is a grid monitoring tool that collects information about the configuration of Worker Nodes in the production grid infrastructure. It does this by providing a jobwrapper that runs before the execution of every grid job. It will check the following:

  • Structural information (hostname, queue, ce, site)
  • Job information (id, vo, vomsgroup/role/cap...)
  • System information (osname, processor, RAM...)
  • Version of java, perl, python, gLite, GFAL, glexec

Information about a worker node and its environment are sent to SWAT server via ActiveMQ messages. A server retrieves these information and stores them in SWAT database. The web application visualizes the data for statistical purposes (
