gLite Worker Node
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 (http://gridops.cern.ch/swat/region/).
