Software Update: HTCondor 9.9.0 / 9.0.13

The HTCondor Team at the University of Wisconsin-Madison has released new feature and long-term support versions of its workload management system HTCondor. The version numbers have ended up at 9.9.0 and 9.0.13. 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 demonstratedand in 2020 the National Science Foundation chosen HTCondor as part of its Partnership to Advance Throughput Computing† The summary adjustments of these expenditures are as follows:
