Download HTCondor 8.5.8 / 8.4.10

The HTCondor Team at the University of Wisconsin-Madison has released both a new stable version and a new development version of its workload management system HTCondor. The version number has landed at 8.5.8 for the development branch and 8.4.10 for the stable branch. HTCondor focuses on the management of compute-intensive tasks and can distribute them over several connected nodes. The user sends his task to HTCondor, 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. HTCondor can, for example, control a dedicated Beowulf cluster, but also regular desktops that have nothing to do for a while. During the day SC16 Google, Fermilab and the HTCondor Team have a 160k-core cloud-based elastic compute cluster demonstrated. The announcements for these releases are as follows:
