Parallel Programming

National Tsing Hua University - CS 542200 Course's Instructor: Jerry Chou.

This repository includes all labs and homeworks covering MPI, OpenMP, Pthread and CUDA.

I provide some template tools for you to calculate IO, CPU and Compute time. Besides, I also provide some tools for you to draw the bar and line graph.

Lab1

• Lab1 needs you to calculate how many pixels in a circle in order to make you get familar with MPI usage.
• Scoreboard Rank: 3/54

HW1

• HW1 needs you to implement odd-even sort with MPI.
• Scoreboard Rank: 4/49
• Result

Lab2

• There are three labs this time including Pthread, OpenMP and hybrid of MPI and OpenMP.
• These three labs require you to do the same problem as the lab1 to calculate how many pixels in a circle.
• Scoreboard rank (Pthread): 4/48
• Scoreboard rank (OpenMP): 3/47
• Scoreboard rank (OpenMP+MPI): 2/48

HW2

• HW2 needs you implement mandelbrot set with Pthread and hybrid of MPI and OpenMP.
• Scoreboard rank (Pthread): 2/47
• Scoreboard rank (OpenMP+MPI): 2/47
• Result

Lab3 && Lab4

• Lab3 needs you to calculate Sobel of the images with CUDA.
• Lab3 Result
• Lab4 needs you optimize kernel calculation.
• Lab4 Solution

HW3

• HW3 needs you to implement All-Pairs-Shortest-Path with multiple threads, single GPU and multiple GPU
• HW3 optimization skill
• Scoreboard rank (multiple threads): 13/41
• Scoreboard rank (Single GPU): 7/40
• Scoreboard rank (Multiple GPU): 2/40
