The code can be compiled using the following command

mpicc gauss_mpi.c -o gauss_mpi

For running the code

mpirun -np 2 ./gauss_mpi 4 0 1

Arguments are as follows

1. Array Dimension
2. Random seed
3. Number of threads (Can be any value. I didn't change the code for accepting the arguments from the serial program)

Pthreads

The code can be compiled using these commands

cc -pthread -o gauss_pthreads gauss_pthreads.c

For running the code

./gauss_pthreads 2000 0 10

Arguments are as follows

1. Array Dimension
2. Random seed
3. Number of threads
