JobVisor

Support for end users

JobVisor provides an intuitive web-based interface that lets users submit jobs, launch interactive applications, monitor workloads and collaborate with colleagues, without needing extensive knowledge of Slurm or command-line tools.

How JobVisor helps

JobVisor allows users to:

• Submit batch jobs through simple web forms
• Launch interactive desktop sessions
• Run GUI-based HPC applications
• Monitor job progress and resource utilization
• View historical job performance and efficiency metrics
• Share running jobs with collaborators
• Estimate queue wait times before submitting jobs

All workloads continue to run through the cluster scheduler, so administrators keep full control over resource allocation and policy enforcement.

Administrator-controlled templates

At the core of JobVisor is a powerful template system that lets administrators create standardized workflows for users. Using a visual template editor, administrators can:

• Define job templates with custom names, icons and tags
• Restrict access based on user roles and permissions
• Control which job parameters users can modify
• Set minimum and maximum values for resources such as CPUs, memory and runtime
• Automatically generate Slurm directives and submission scripts
• Create simple form-based interfaces tailored to specific applications

Templates use Jinja-based scripting and support point-and-click insertion of Slurm variables, making it easier than ever to create sophisticated workflows without extensive scripting knowledge.

Intelligent job insights

JobVisor includes several features designed to help users make better scheduling decisions and improve cluster utilization.

Before submitting a job, users can request an estimated queue start time and projected completion time based on current cluster conditions. This gives greater visibility into scheduling and helps users plan workloads more effectively.

Once jobs are complete, users can review historical performance information, including:

• CPU efficiency
• Memory efficiency
• Time efficiency
• Resource requests versus actual utilization

These insights help users optimize future workloads and improve overall cluster efficiency.

Collaboration and interactive computing

For interactive workloads, users can launch desktop sessions and GUI-based applications directly from the interface. Multiple versions of an application can be made available, so users can choose the environment that best fits their needs. Interactive jobs can be shared with colleagues, with a choice of read-only access or the ability to interact with the running GUI environment.

Cluster visibility for everyone

In addition to job management, JobVisor gives users visibility into overall cluster health and utilization. Users can view current allocations, available resources and overall cluster status through an easy-to-understand dashboard.
