Parallel Processing

Post by pramod_au »

Hello
I was reading through Parallel JobDeveloper Guide.
I have few questions.

1. If I design for a multiprocessor architecture say (Partition parallel processing) for 4 CPU Units.Then I upgrade my system to 8 CPU unit system, but i failed to update my Configuration File!!!

will the JOB use 4 processors or 8 processors?

Regards
pramod

Depends.

It will initially use four CPUs, because you haven't updated the configuration file.
However, and depending on how your actual jobs are designed, any single job may run in more than one process, and the operating system scheduler may or may not choose to assign these to the other CPUs.
I would not rely on this, though; I'd update my configuration file.
