This is the same question as the last one I asked, just forgot to add a few details. I honestly don't know what to do with this homework assignment. I'm confused about what MPI is and how to use it in code. May someone please explain it? It has to be written in C.

Question
This is the same question as the last one I asked, just forgot to add a few details. I honestly don't know what to do with this homework assignment. I'm confused about what MPI is and how to use it in code. May someone please explain it? It has to be written in C.
Transcribed Image Text:In the following figure shows how to distribute amount of work between 8 processes (See
lecture 7, page 21):
Processes

Write an MPI program to generate a random number in the range 0-10 for each process.
Your MPI program must works for 1, 2, 4, 8, 16, 32, 64, 128 process.
Note: Assume the user enters power of 2 for the numbers of processes.
The following is just a sample from my program for 128 processes. Your program must
work for any number of processes that is a power of 2:
How many processes: 128
Output:
9, 8, 2, 2, 0, 0, 7, 6, 8, 4, 0, 8, 7, 0, 1, 9, 5, 6, 4, 5, 0, 0, 1, 2, 6, 4, 0, 3, 6, 3, 3, 0, 9, 7, 7, 8,
7,9, 3, 5, 4, 1, 3, 1, 6, 1, 8, 1, 7, 8, 7, 6, 3, 1, 0, 2, 5, 2, 7, 5, 3, 6, 1, 9, 6, 5, 4, 9, 3, 1, 0, 0,
8, 0, 8, 4, 5, 7, 5, 2, 2, 2, 4, 8, 0, 2, 6, 2, 9, 5, 2, 7, 8, 9, 5, 3, 1, 9, 8, 2, 8, 6, 5, 6, 7, 5, 7, 7,
6, 7, 9, 2, 1, 7, 4, 1, 3, 5, 1, 6, 3, 4, 4, 8, 6, 8, 0, 6,
Sum = 574
