Assignment for Parallel Programming using C++ and MPI

Introduction

• Matrix.h and Matrix.cpp conduct Matrix-Vector Multiplication.
• Trap.h and Trap.cpp conduct Trapezoidal Integral.
• OddEvenSorting.h and OddEvenSorting.cpp conduct Odd Even Sort.
• MPIApp.cpp contains the main function.

Usage

• compile with mpic++ (using c++11 with argument -std=c++11)

mpic++ -std=c++11 -c Matrix.cpp Trap.cpp OddEvenSorting.cpp MPIApp.cpp

• link with g++

mpic++ Matrix.o Trap.o OddEvenSorting.o MPIApp.o -o app

• use app

# default arguments:
#     total = 10000
#     m = 500
#     n = 500
mpirun -np $(#process) app 1  # test Matrix-Vector Multiplication
mpirun -np $(#process) app 1 $(total)  # specify the total number of tests
mpirun -np $(#process) app 1 $(m) $(n)  # specify the shape (m*n) of the matrix
mpirun -np $(#process) app 1 $(total) $(m) $(n)  # specify the total number of tests, and the shape (m*n) of the matrix

# default arguments:
#     total = 10000
#     range = 100
#     n = 1000000
mpirun -np $(#process) app 2  # test Trapezoidal Integral
mpirun -np $(#process) app 2 $(range) $(n)  # specify the range of the integral interval and the number of trapezoids
mpirun -np $(#process) app 2 $(total) $(range) $(n)  # specify the total number of tests, the range of the integral interval and the number of trapezoids

# default arguments:
#     total = 10000
#     n = 10000
mpirun -np $(#process) app 3  # test Odd Even Sort
mpirun -np $(#process) app 3 $(n)  # specify the list length
mpirun -np $(#process) app 3 $(total) $(n)  # specify the total number of tests and the list length

• Any other command will be rejected by the application.
