Batch jobs are non-interactive programs, such as reports and procedures, that run in the background. That is, the program runs in a separate process and does not interfere with your task. For example, the program that performs data validation runs without input from you, and without showing any output on your screen.

The main difference between cron and anacron is that the former assumes that the system is running continuously. If your system is off and you have a job scheduled during this time, the job never gets executed. On the other hand anacron is 'anachronistic' and is designed for systems that are not running 24x7.

But nginx does not require context switching, since a single thread can serve all requests (actually we typically configure nginx to run in as many processes as there are CPU cores). This is the main reason why nginx is faster, meaning it can serve more requests per second than Apache on the same hardware.

Another common issue is related to the environment variable. You tested your script by excuting it from the command line and it worked as expected but somehow it didn't work in crontab.

Yes, threads and processes can run concurrently on multi-core CPUs, so this works as you describe (regardless of how you create those threads and processes, OpenMP or otherwise). A single process or thread only runs on a single core at a time.

A job has one start place, and executes one step at a time, with one flow through the steps. A transformation has many possible start places and all steps execute in parallel. If a step has a step before it, it will take the data in there, and use it.
