gLite Computing Element

1. Release Description

This release contains the gLite Computing Element module v. 2.0.2. The following sections provide additional information about the release content, the module dependencies, the know bugs and issues and a list of bugs closed since the previous release. For information about installing and using the gLite Computing Element, please refer to the gLite Installation and User Guides.

2. Changes in this Release

This release includes the following changes (more information can be found on the gLite Installation Guide):

• New CE Monitor web application with better control on notifications and on activation and expiration of subscriptions
• Use a new security model in the authentication/authorization with WMS server based on GSI. No need to specify the Condor queue superusers to match real WMS accounts
• New BLAHP Log Parser daemon allows installing the CE and the LRMS on separate servers
• New option to discover existing pool accounts created with external systems
• New option to avoid pre-configuring the pool accounts when the home directories are on shared file systems (inaccessible to the root user) (it should be used together with a relocation of the glite_setenv.sh file to /etc/profile.d). This functionality is activated using the modify.user.env parameter in the glite-global.cfg.xml file
• The configuration script now has a new --configure command line switch to execute the configuration steps only without starting the services. The --start switch must be used to start the services. Running the script without options print usage instructions
• R-GMA Service Publisher parameters updated to use new common conventions (please make sure you use the new configuration templates)
• The following additional parameters have been added to the configuration file:
  use.log.parser                (user parameter)
  log.parser.address         (user parameter)
  account.discovery          (advanced parameter)
  notifications.condition     (advanced parameter)
  pbs.log.parser.port         (advanced parameter)
  lsf.log.parser.port          (advanced parameter)
  ce-monitor.DOCBASE  (system parameters)
• Bug fixes

5. Known bugs and issues

This release has the following bugs and issues. Bug numbers refer to the gLite Bug Tracking system database hosted on the CERN Savannah system at https://savannah.cern.ch/bugs/?group=jra1mdw .

• Currently jobs get a full proxy rather than a restricted one as done in LCG. This is needed for multi-hop submission (as e.g. to condor pools but also eventually for CE – CE submission) and apparently GT4 abandoned support for restricted proxies. Security implications need to be better understood. Currently being discussed in the MWSCG (Bug 7425)
• During the execution of the CE configuration script, a number of Globus configuration scripts are executed. One of these scripts outputs the following error (BUG #5992):
  
  […]
  
  running /opt/globus/setup/globus/setup-globus-gram-reporter-fork..[ Changing to /opt/globus/setup/globus ]
  Setting up fork gram reporter in MDS
  -----------------------------------------
  Error fork GRAM reporter entry jobmanager-fork. Aborting!
  ERROR: Command failed
  
  […]
  
  This error doesn’t affect the correct functionality of the CE and can be ignored.
• The CE Monitor doesn’t correctly publish Condor queues. This will be fixed in a future release
• This release include a tech preview of the GT4 Workspace Service that can be used as an alternative to the pool accounts method for creating and configuring the user execution space. This preview can be activated by using the alternative configuration script glite-ce-wss-config-py. This script requires Apache Ant v. 1.6.1 or greater to be installed and properly configured on the server. Please refer to the Apache Ant user manual for the details
• No removal procedure is provided with this release apart from the removal of the RPMS. Any account, group or other resource created during the module configuration must be manually cleaned up.
