JobSchedulers.jl

A Julia-based job scheduler and workload manager inspired by Slurm/PBS and Crontab.

Why JobScheduler?

We may find different tasks or programs use different CPU and memory. Some can run simultaneously, but some have to run sequentially. JobScheduler is stable, useful and powerful for task queuing and workload management, inspired by Slurm/PBS and Crontab.

Rich Features

• Job and task scheduler.

• Local workload manager.

• CPU, memory and run time management.

• Deferring a job until specific jobs reach specific states (dependency).

• Running a job at specific time, or a period after creating (schedule).

• Job-dependent stdout and stderr. Yes, global stdout and stderr are thread-safe with this package!

• Recurring/repetitive jobs using Cron-like schedule expressions.

• Automatic backup and reload.

• Minimum overhead: from creation to destory, a job only takes extra 1-2 µs.

• Fancy progress meter in terminal.

  

Installation

JobSchedulers.jl can be installed using the Julia package manager. From the Julia REPL, type ] to enter the Pkg REPL mode and run

pkg> add JobSchedulers

To use the package, type

using JobSchedulers
