Beginner for MPI programming

[f***@gmail.com]

Hello all,

I'm a beginner to MPI Programing in C. Need some help in this
regard.

I found that, MPI also has datatypes. But not getting why these
required & how to use.
What else needs to be concentrated, before to start coding?

As a beginner I want to start with the following example:

Problem: Finding the prime numbers between 1 to 1000

The problem size 1-1000 is divided into 10 parts and executed across
10 processes.

How this can be coded?

Thanks,
Sangamesh

I found the MPI standard document informative enough to start coding.
For your convenience the 1.x and 2.0 standard documents were recently
merged into the latest 2.1 standard paper available in several versions
here:

Thank you. I'll go thru the documents.
