How to Manage Many Jobs

Often, you may need to run many nearly identical jobs. There are different approaches to achieve this goal with minimal effort and some of the approaches will be described below. Which approach best suits your needs depends on the nature of your problem but some hints are given for making the choice.

$ ./isprime 73
