The cron command-line utility is a job scheduler on Unix-like operating systems. Users who set up and maintain software environments use cron to schedule jobs [ 1 ] (commands or shell scripts ), also known as cron jobs , [ 2 ] [ 3 ] to run periodically at fixed times, dates, or intervals. [ 4 ]
A job scheduler is a computer application for controlling unattended background program execution of jobs. [1] This is commonly called batch scheduling , as execution of non-interactive jobs is often called batch processing , though traditional job and batch are distinguished and contrasted; see that page for details.
VisualCron is a replacement for the Windows Task Scheduler and a similar cron job scheduler in Unix-like operating systems. [1] The software is split into client and server parts, with the former being invoked by the user on demand and the latter always running as a process in the background. [1]
This is a list of notable job scheduler software. Job scheduling applications are designed to carry out repetitive tasks as defined in a schedule based upon calendar and event conditions. This category of software is also called workload automation. Only products with their own article are listed: ActiveBatch; Apache Airflow; Cron; DIET; HTCondor
The scheduler is an operating system module that selects the next jobs to be admitted into the system and the next process to run. Operating systems may feature up to three distinct scheduler types: a long-term scheduler (also known as an admission scheduler or high-level scheduler), a mid-term or medium-term scheduler, and a short-term scheduler.
Task Scheduler (formerly Scheduled Tasks) [1] is a job scheduler in Microsoft Windows that launches computer programs or scripts at pre-defined times or after specified time intervals. [2] [3] Microsoft introduced this component in the Microsoft Plus! for Windows 95 as System Agent. [4] Its core component is an eponymous Windows service. [5]
List scheduling is a greedy algorithm for Identical-machines scheduling.The input to this algorithm is a list of jobs that should be executed on a set of m machines. The list is ordered in a fixed order, which can be determined e.g. by the priority of executing the jobs, or by their order of arrival.
Critical path drag is a project management metric [1] developed by Stephen Devaux as part of the Total Project Control (TPC) approach to schedule analysis and compression [2] in the critical path method of scheduling. Critical path drag is the amount of time that an activity or constraint on the critical path is adding to the project duration.
