scancel

Scancel is a command line tool primarily used in a Linux environment for managing and canceling jobs submitted to a job scheduler. It is commonly used with the SLURM workload manager to control and monitor jobs running on high-performance computing (HPC) clusters.

It allows users to cancel or terminate specific jobs that are executing or already queued in the scheduler. By specifying job IDs or job name patterns, scancel can identify the jobs to be canceled. It offers a range of options for selecting and filtering jobs based on various criteria such as user, partition, job state, or submission time.

In addition to job cancellation, scancel can also be used to perform other actions such as suspending, resuming, or signaling jobs. It supports advanced features like batch job submission or holding/holding release of jobs.

Scancel is a versatile tool that provides administrators and users with efficient control over their jobs in a distributed computing environment. It plays a crucial role in managing the workload and troubleshooting issues on HPC systems. Its flexibility and power make it an essential tool for effective job management in a cluster environment.
