2. Obtaining and Installing Software

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.

2.1. Java Client API Download

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.

8. Summary of Changes Since 5.0.1 (by component)

8.1. Summary of Changes in GridFTP

  • Error message displayed when the connection limit is exceeded at the server has been changed

8.2. Summary of Changes in RLS

  • None since GT 5.0.1.

8.3. Summary of Changes in GRAM5

  • 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 command. To simplify debugging LRM interface problems.
  • A new tool globus-gram-streamer implements stdio streaming similar to gram2, for use with the 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.
