8.2 Upgrading from the 7.4 series to the 7.6 series of Condor

Upgrading from the 7.4 series of Condor to this 7.6 series will bring many features introduced in the 7.5 series of Condor. While nothing will replace reading through the version histories, here is a list of some new features and release notes to be aware of.

• Condor's RPMs now use FHS locations for files. See section 3.2.6 for updated installation information.

• The locations of many executables within the release directories have changed.

• Condor's file transfer mechanism now provided limited support for the transfer of directories.

• The feature set once known as the Startd Cron or as Hawkeye is now called Daemon ClassAd Hooks. Besides the new name, the mechanisms have been updated and significantly revised. See section 4.4.3 for documentation.

• Condor DAGMan provides new features. See section 2.10 for documentation.

• Grid jobs targeted at CREAM, EC2 servers and Eucalyptus systems are now supported.

• For those who compile Condor from the source code, rather than using packages of pre-built executables, Condor is now built using cmake instead of imake.

• Quill is now available in the source code, and it is not incorporated as part of pre-built and released executables.

• The condor_job_router is no longer limited to routing vanilla universe jobs.

• Condor uses the New ClassAd language internally.

• The condor_shared_port daemon allows Condor daemons to share a single network port. This makes opening access to Condor through a firewall easier and safer. It also increases the scalability of a submit node by decreasing port usage.
