HTCondor vs IBM Spectrum Symphony

HTCondor is a free workload management system for compute-intensive jobs. It queues and schedules work, sets priorities, and monitors and manages computing resources across networked clusters, cloud resources, and international grids. Its ClassAd mechanism matches job requests with machine offers using configurable requirements and preferences. If a machine becomes unavailable during a job, HTCondor can restart that job on another machine. It can transfer job data when machines do not share a file system, or route job input and output through the submit machine. Separate installations can collaborate through flocking, and HTCondor-G works with Globus-managed resources. It is self-hosted and supports Linux, MacOS, and Windows. Feature release 25.14.1 adds a metric daemon that exports metrics to Prometheus and Ganglia. HTCSS is licensed under Apache License 2.0 and distributed without warranties or conditions. Contracted support is available; fees vary by support policy.
