Introduction
Motivations for using a batch system
- more effective usage of available computers (e.g. more uniform load)
- usage of resources 24h/day
- assignment of resources according to policies (who gets how much CPU when)
- quicker execution of tasks (system knows most powerful least loaded nodes)
You tell the batch system a script name and what you need in terms of disk space, memory, CPU time
The batch system guarantees fastest possible turnaround
Could even be used to get xterm windows on least loaded machines for interactive use (later)
