Condor 7.6.1

Het Condor Team van de Universiteit van Wisconsin-Madison heeft een nieuwe stable-versie uitgebracht van hun 'workload management system' Condor. Het versienummer is aanbeland bij 7.6.1 en het pakket wordt onder de Apache 2.0-licentie uitgegeven. Condor richt zich op het beheer van rekenintensieve taken en kan deze over meerdere aangesloten nodes verdelen. De gebruiker stuurt zijn taak naar Condor waarna deze het proces afhandelt op basis van ingestelde policy's en de beschikbaarheid van aangesloten resources, om tot slot de resultaten naar de gebruiker terug te sturen. Condor kan bijvoorbeeld een dedicated Beowulf-cluster aansturen, maar ook gewone desktops die even niets te doen hebben. De aankondiging met de lijst van aanpassingen van deze uitgave ziet er als volgt uit:

Condor 7.6.1 released!

The Condor team is pleased to announce the release of Condor 7.6.1. See the Version History for a complete list of changes. Condor 7.6.1 binaries and source code are available from our Downloads page.

Bugs Fixed:

• condor_q -analyze failed to provide detailed analysis of the job's requirements expression when the expression contained ClassAd function calls in some cases.
• Fixed a segmentation fault bug introduced in Condor version 7.5.5, in the checkpoint and restart of jobs using compressed checkpoint images under the standard universe. By default, Condor will not compress checkpoints under the standard universe. Jobs which do not compress their checkpoints were immune to this bug. Compressed checkpoints are only available in 32-bit versions of Condor. Generation of checkpoints in 64-bit versions of Condor are unaffected.
• In Condor version 7.6.0, the condor_schedd would create a spool directory for every job. The corrected and previous behavior has now been restored, which is to create a spool directory only when needed.
• Fixed a bug introduced in Condor version 7.5.2, that caused the condor_negotiator daemon to crash if any machine ClassAds contained cyclical attribute references.
• Fixed a bug that caused usage by nice_user jobs to be charged to the user directly rather than `nice-user.user'. This bug was introduced in the 7.5 series.
