The Laser Interferometer Gravitational-Wave Observatory (LIGO) unlocked the final door to Albert Einstein's Theory of Relativity, winning the Nobel prize this week and proving that gravitational waves produce ripples through space and time. Since 2004, HTCondor has been a core part of the data analysis effort. See this recent article , as well as this one, for more details.

The HTCondor team is pleased to announce the release of HTCondor 8.7.3. This development series release contains new features that are under development. This release contains all of the bug fixes from the 8.6.6 stable release. Enhancements in the release include: Further updates to the late job materialization technology preview; An improved condor_top tool; Enhanced the AUTO setting for ENABLE_IPV{4,6} to be more selective; Fixed several small memory leaks. Further details can be found in the Development Version History and the Stable Version History. HTCondor 8.7.3 binaries and source code are available from our Downloads page.

The HTCondor team is pleased to announce the release of HTCondor 8.6.6. A stable series release contains significant bug fixes. Highlights of this release are: HTCondor daemons no longer crash on reconfig if syslog is used for logging; HTCondor daemons now reliably leave a core file when killed by a signal; Negotiator won't match machines with incompatible IPv{4,6} protocol; On Ubuntu, send systemd alive messages to avoid restarting HTCondor; Fixed a problem parsing old ClassAd string escapes in the python bindings; Properly parse CPU time for Slurm grid universe jobs; Claims are released when parallel univ jobs are removed while claiming; Starter won't get stuck when a job is removed with JOB_EXIT_HOOK defined; To reduce audit logging, added cgroup rules to SELinux profile. More details about the fixes can be found in the Version History. HTCondor 8.6.6 binaries and source code are available from our Downloads page.

Researchers and software engineers at the Intel-Broad Center for Genomic Data Engineering build, optimize, and widely share new tools and infrastructure that will help scientists integrate and process genomic data. The project is optimizing best practices in hardware and software for genome analytics to make it possible to combine and use research data sets that reside on private, public, and hybrid clouds, and have recently identified HTCondor on their web site as an open source framework well suited for genomics analytics.

The HTCondor team has released updated RPMs for HTCondor versions 8.4.12, 8.6.5, and 8.7.2 running on Enterprise Linux 7. In the recent Red Hat 7.4 release, the updated SELinux targeted policy package prevented HTCondor's SELinux policy module from loading. Red Hat Enterprise Linux 7.4 systems running with SELinux enabled will require this update for HTCondor to function properly.

The HTCondor team is pleased to announce the release of HTCondor 8.6.5. A stable series release contains significant bug fixes. Highlights of this release are: Fixed a memory leak that would cause the condor_collector to slowly grow; Prevent the condor_starter from hanging when using cgroups on Debian; Fixed several issues that occur when IPv6 is in use; Support for using an ImDisk RAM drive on Windows as the execute directory; Fixed a bug where condor_rm rarely removed another one of the user's jobs; Fixed a bug with parallel universe jobs starting on partitionable slots. More details about the fixes can be found in the Version History. HTCondor 8.6.5 binaries and source code are available from our Downloads page.
