Release Notes 5.5

GridWay 5.5 is the new development version of the fifth series of the metascheduler, completely backwards-compatible with version 5.4. Extra features and intensive bug fixing have been worked out.

Release date: October 19th, 2009.

LDAP Information MAD

Regarding the Information Manager (IM) a new Middleware Access Driver (MAD) has been developed for querying a Lightweight Directory Access Protocol (LDAP) server for information about the grid resources available.

XML support

Output of cli

Now the commands gwhost, gwps, gwuser, gwhistory and gwacct accept a -x flag formatting all the information according to XML standards.

XML schema

A new validation schema has been added to the distribution in order to validate the output of the command line interface. It is located under the xml_schema/ folder.

Improved configuration script

The testing performed at the configuration stage before installation exits if the perl and ruby library requirements are asked for but not satisfied. They correspond to the --enable-ldap and --enable-drmaa-ruby options of ./configure.

On-line documentation

To avoid the duplication effort and improve the browsing experience through the different documentation sources, we have migrated all the documents to our on-line section. You won't find anymore a doc/ folder.
