inter process and intra process

What is difference between inter process and intra process stages?Thanks in advance.
It's in the documentation, one such place would be under Job Properties.

Mostly - one of the stages exists, and one of them doesn't. One type only works on SMP systems.

In process uses buffers to pass data between stages, where as interprocess runs a seperate process for each active stage in SMP environment.pavan31081980 wrote:What is difference between inter process and intra process stages?Thanks in advance.

The problem with just answering brief questions of this nature from people with low post counts is the very distinct possibility they are just here to farm answers for interview questions. Which is a practice highly frowned upon here. 
<- See, that's me frowning.
This looks too much like one of those to me. Not saying that's necessarily the case with Pavan, just that the possibility exists so answers are generic and point to documentation. They are free to come back and clarify their question, ground it in more practical terms and how it relates to a specific problem they are working on.
Until then we generally refrain from outright answers. FYI.

Thanks Craig ! I will follow the same practice.

SMP is irrelevant. Both work on a single CPU system.

Come on, it's not irrelevant as in "unrelated to the matter being considered". It may be less relevant than my 'only works on' statement would lead one to believe, that wasn't quite true. Sure it 'works' on a single CPU system but it is really meant for use on SMP systems. Yes?
And all we're referencing is the online help:
"Inter process. Use this if you are running server jobs on an SMP parallel system. This enables the job to run using a separate process for each active stage, which will run simultaneously on a separate processor."
It's not too hard to infer that there's no benefit per se on a non-SMP server after reading those sentences.
