Parallel program and sequential for Matrix-Vector multiplication

This program executed on Linux CentOS.

• Sequential:

This program used here to compare the results (i.e. execution time) with the parallel program.

• To compile this program on the terminal, type this command:

  gcc -o sequential Sequential.c

  Object file with name sequential will be generated, to execute this file, type this:

  ./sequential

• Parallel:

This program use multiprocessing technique via MPI library, i.e. the execution will be on multiprocessors.

• To compile this program, type this:

  mpicc -o parallel MPI_Parallel.c

• To execute the object file, type this:

  mpirun -np 4 parallel

Note: Number 4 in the last command represents the number of processors that will be used in the execution of the program.
