The GT development team is pleased to make a new stable release of the Globus Toolkit available for download.
GT5 does not include any of the Web Service components from GT4.
Highlights of this release include:
- Synchronization (globus-url-copy -sync) feature that transfers files only if they do not exist at the destination or differ from the source
- An offline mode for the server
- Improvements have been made to address all the known blocker issues for production deployment on TeraGrid and OSG.
- Updated to MyProxy v5.2
For highlights of changes in each component, see Section 8, “Summary of Changes Since 5.0.1 (by component)”.
To download this release, go to the 5.0.2 Download page.
For information on installing this release, go to the 5.0.2 Installation Guide.
GT 5.0 does not include any of the CoG JGlobus Java APIs that were included in the GT4 release series. But, the JGlobus APIs can still be used with the GT5 services. You can get them directly from the CoG JGlobus releases; see the following link:
Consider the following when determining which version of CoG JGlobus to use:
The GRAM development team used CoG JGlobus version 1.6.0 for performance testing.
The BIRN project used CoG JGlobus version 1.6.0 (plus patches) for GridFTP testing. All patches are included in 1.8.0.
At the time of the GT 5.0.2 release, 1.8.0 was the recommended version. In general, the latest recommended CoG JGlobus version should be used.

These are some platform notes for 5.0.x in particular:

Feel free to offer any suggestions or feedback using JIRA (the "Documentation" project). Note at the time of this release, the documentation feedback box that used to appear at the bottom of each page is not functioning after the recent website redesign. We are working on the matter and will have the feedback box available as soon as possible. Please note that this box is intended for feedback and suggestions only - for support, please read the following section.

- Error message displayed when the connection limit is exceeded at the server has been changed
- New RSL attribute
save_job_description. If set to
yes, the job manager will write a file in the HOME directory of the user containing the perl representation of the job. This can be used to debug LRM interface problems.
- Added command-line help for the globus-job-manager-script.pl command. To simplify debugging LRM interface problems.
- A new tool globus-gram-streamer implements stdio streaming similar to gram2, for use with the grid-monitor.sh script from Condor. As a result, a Condor-G client which does not know about GRAM5 features will be able to submit many jobs to a GRAM5 server.
- Eliminated the need for a global Condor log file and SEG module to parse it. In this version, the Condor logs are per-job and removed automatically by the job manager when the job is cleaned up.
- Resolved the TeraGrid SGE issues on Ranger and PBS issues on Queen Bee.
Other than bugfixes, no changes have occurred for SimpleCA since the last stable release, 5.0.1.
- The TCP driver has been modified to randomize the selection of ephemeral ports.
- Minor code cleanups.
No significant changes have happened for C Common Libraries since GT 5.0.1. See Feature Summary for some minor changes.
