Parallel-Processing

CMPE 478: Parallel Processing HW 1

Generating Prime Numbers

We needed to parallelize given prime number generator algotihm using OpenMP.

Prime Number Generator

To generate prime numbers first make the project by running following commands:

cmake ../Parallel-Processing/
make

or

g++ --openmp -o prime main.cpp

Then run the program like this:

./prime [Scheduling Type] [Chunk Size] [M] [Thread Num] [--print]

Scheduling type can be "STATIC", "DYNAMIC", "GUIDED" or "AUTO". When the scheduling type is "AUTO", chunk size is not important but please put there a number so that program runs without any errors.

If you want to see the prime numbers that are generated, put --print option in the end.

Performance Analysis

To see the analysis, run ./primeAnalysis.sh. You can run this file without making the project since it makes it.

NOTE: "primeAnalysis.sh" program generates a file named "PrimeNumberGeneratorAnalysis.csv". So please be careful if you have a file with the same name since the program overwrites it.

There is an example csv file that contains the results generated on my computer called "ExampleAnalysis.csv".
