HTCondor vs schedulix

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.

Schedulix is open-source workload automation software for building and running IT process workflows. Its browser interface supports administration, workflow design, monitoring, and operations across systems. Scheduling can choose processes dynamically while accounting for priorities and available resources. Workflow structures include exit states, batch and job hierarchies, dependencies, resources, and triggers. Schedulix provides a documented API, and its RDBMS repository supports SQL read access through Standard Catalog Interface views. The product describes authentication for users, job server agents, and user processes, along with delegated system privileges and an audit trail of operator interventions. The maker says components restart without manual intervention after hardware, power, or operating-system failures, provided the RDBMS data remains secure. Source code is available on GitHub, and downloads include an RPM repository package and Windows packages. The software is free under the GNU AGPL and supports Linux, Windows, web, API, and self-hosted use. The maker also says users can move to proprietary BICsuite editions without losing work. Paid support eligibility is limited to installations from an unmodified official source copy or an independIT package.
