Download Condor 7.8.0

The Condor Team at the University of Wisconsin-Madison has released a new stable version of its workload management system Condor. The version number has landed at 7.8.0 and the package is under the Apache 2.0 License issued. Condor focuses on the management of compute-intensive tasks and can distribute them over several connected nodes. The user sends his task to Condor, after which it handles the process based on set policies and the availability of connected resources, and finally sends the results back to the user. Condor can, for example, control a dedicated Beowulf cluster, but also regular desktops that have nothing to do for a while. The announcement with the list of changes to this release is as follows:

Condor 7.8.0 released!

The Condor team is pleased to announce the release of Condor 7.8.0. This is the first entry in a new stable series, contains all the features and bug fixes in the 7.7 development series. See the version History for a complete list of changes.

New Features:

• (Added in 7.7.6.) Added the -_condor_relocatable argument for standalone checkpointing. This allows checkpointed programs to restart without attempting to change to their original directory. (Ticket #2877).
• (Added in 7.7.5.) Added the -absent flag to condor_status, which displays absent ads. (Ticket #2690).
• (Added in 7.7.5.) Implement absent ads, which help track pool membership in a persistent way. (Ticket #2608).

Configuration Variable and ClassAd Attribute Additions and Changes:

• The job ClassAd attribute RemotePool is now saved in LastRemotePool when the job finishes running.

Bugs Fixed:

• (Fixed in 7.7.6.) Fix -absent, -vm, and -java flags to condor_status so that they work with the -long option. (Ticket #2943).
• Support glob() on Scientific Linux 6 and others using the new Linux system call fstatat(), but only when not using remote system calls. (Ticket #2945).
• Fixed potential started crash introduced in v7.7.5 when claiming a partitionable slot that was in the Owner state. (Ticket #2936).
• When ClassAd function stringListMember() is called with an empty string as the second argument, it now evaluates to False. Previously, it incorrectly evaluated to Undefined. (Ticket #2953).
• Format tags %v and %V for the -format option now properly print all ClassAd value types. Previously, True and False were printed as integers, and new ClassAd types like lists and nested ads couldn’t be printed. (Ticket #2960).
• Restored RCS keyword strings CondorVersion and CondorPlatform to the Condor binaries. These strings are found and printed by the ident program on unix. They were missing in Condor versions 7.7.3 and later. (Ticket #2932).
• condor_job_router failed to route spooled source jobs. (Ticket #2955).
• Fixed a bug on Debian 6 and RHEL 6 that could cause standard universe jobs to never checkpoint. This would happen if the job triggered a call to NSCD (Name Service Caching Daemon) but NSCD wasn’t running. Calls to NSCD can be triggered by a lookup of a user account or resolving a machine hostname to an IP address. Now, NSCD is never consulted by a standard universe job (this was already the behavior on other platforms). (Ticket #2973).
