SudokuMP by Marko R
SudokuMP solves sudoku puzzles given a txt file arranging the puzzle and the size of the puzzle. There are two methods to solve said puzzles the brute force method and the humanistic solver. Profiling wasn't performed on the humanistic solver since it manages to solve all the 16x16 puzzles extremely quickly the worst of them (expert) still being at around 12ms. The expert puzzle is too difficult for the brute force method and takes over an hour to run so it wasn't profiled. The project can be found here: SudokuMP
Running the Program
The git repository comes with a pre-compiled version of the program so you can run it immediately (you might need to give it the correct permissions to run). The git repository also comes with a make file so if you want to compile your own version delete the pre-compiled version and run make. The program takes two command line arguments the first being the path to the txt file containing the sudoku puzzle and the second argument being the size of the puzzle cells.

Analysis / Code Snippet
The two functions which dominate the runtime of this program are create_copy_board which accounts for roughly 60% or more of the exceution time and choose_cell_bf which accounts for another 20% generally.
Board* create_copy_board(Board* b){
Board* copy_board = new Board(b->dim);
for(int row = 0; row < b->dim; row++) {
for(int col = 0; col < b->dim; col++) {
copy_board->solution[row][col] = b->solution[row][col];
for(int index = 0; index < b->dim; index++) {
copy_board->cells[row][col][index] = b->cells[row][col][index];
}
}
}
copy_board->cells_solved = b->cells_solved;
return copy_board;
}
/* Choose cell with the least number of possible values
* Return 0 if that cell has 0 values
*/
bool choose_cell_bf(Board* b, int &row, int &col) {
int least = b->dim+1, counter;
for(int r = 0; r < b->dim; r++) {
for(int c = 0; c < b->dim; c++) {
counter = 0;
if(!b->solution[r][c]) {
for(int num = 0; num < b->dim; num++) {
if(b->cells[r][c][num]) {
counter++;
}
}
if(counter < least) {

}
}
}

ColorTransfer by Jadrian S
The Source code can be found here This program is an implementation of image color transfer detailed by Erik Reinhard and coded by Tatsy it use OpenCV to do so. This program takes 2 images the first image denoted by the args is the image being editted with colours. The second image is an image that the program will take the colours from. After the color transfer an image is generated with the color transfer completed and is opened for the user to view.
Creating and Running the Project with gprof profiling
Perform the following steps in a Linux/Unix System:
STEP 1 - Download the following zips and extract their contents as they will be used for later steps
-> test files for opencv:Download OR File:Test.zip -> ColorTransfer:Download OR File:ColorTransfer.zip
STEP 2 - Install all the required entries(make,cmake,git,gprof,etc) with the following terminal command:
-> sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev binutils
STEP 3 - Download and Install OpenCV from their official page located here. You can do this with the following steps and commands:
-> Download the latest source data of OpenCV for Linux/Mac -> Extract the zipped source data into its appropriately named folder opencv-(latest version) -> Open terminal and enter us the cd command to enter the extracted folder opencv-(latest version) -> Create a build directy with the command mkdir build -> Use the cd command to enter the build folder -> Use the following cmake command to generate the appropriate files for the make command: cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. -> Use make with the -j7 command to allow for up to 7 jobs when preparing the install: make -j7 -> Install with: sudo make install -> OpenCV should be installed
STEP 4 - Use the Test Folder provided by the dropbox link above to see if OpenCV is working correctly. You can follow these steps to do so
-> In terminal cd into the test folder -> cmake . -> make -> run display image with the follow command ./DisplayImage ahri.jpg -> If the image provided is displayed OpenCV should be in working order.
STEP 5 - Build the ColorTransfer program with the folder provided by the dropbox link and create a flat profile using gprof
-> Create the files for make using the following command: cmake -DCMAKE_CXX_FLAGS=-pg -DCMAKE_EXE_LINKER_FLAGS=-pg -DCMAKE_SHARED_LINKER_FLAGS=-pg . -> The additional options include -pg within the cmake so that the appropriate gmon.out can be created for gprof -> After the files are generated use the make command -> Run the created program with 2 arguments arg1 being the image beind editted and arg2 being the image to take colours from (two images are provided for your convenience). -> If using the provided image the command should like: ./ColorTransfer ahri.jpg ahri2.jpg -> This should generate the colour transferred output image as well as the appropriate gmon.out file -> Use the either of the following commands for the flat profile: gprof -p -b ./ColorTransfer > ColorTransfer.flt OR gprof test_gprof gmon.out > analysis.txt
Example Output
If using the examples provided you should have the following image results:
Input 1
Input 2

Sorted array processing by Abbas Zoeb
Sorted array processing finds the processing time it takes for an array before and after it has been sorted. This code basically allocates an array with random numbers (array size is 32768). Then the array is sorted using the standard library inbuilt sorting algorithm (which most likely is using Quick Sort). Then another loop is run through the entire array to find all the elements that are above the number '127'. This loop is inside another loop that rotates for another 100,000 times. The loop would go by faster as the array is already sorted and would be much easier now to find elements greater than 127. Profiling was performed on this c++ code on matrix. The project can be found here: [1]
Running the Program
The file can be simply compiled using g++ or clang++ on matrix.
Steps to compile the code and do the profiling on it:
0) Copy the code from GitHub and paste it into a cpp file (I named it sorted.cpp)
1) g++ -Wall -pg sorted.cpp -o sorted
2) ./sorted
3) gprof sorted gmon.out > prof_output
4) cat prof_output
Now you can see the flat and graph profiling for the code.
The Code
#include <algorithm>
#include <ctime>
#include <iostream>
int main()
{
// Generate data
const unsigned arraySize = 32768;
int data[arraySize];
for (unsigned c = 0; c < arraySize; ++c)
data[c] = std::rand() % 256;
// The next loop runs faster because we are using a sorted array
std::sort(data, data + arraySize);
// Test
clock_t start = clock();
long long sum = 0;
for (unsigned i = 0; i < 100000; ++i)
{
// Primary loop
for (unsigned c = 0; c < arraySize; ++c)
{
if (data[c] >= 128)
sum += data[c];
}
}
double elapsedTime = static_cast<double>(clock() - start) / CLOCKS_PER_SEC;
std::cout << elapsedTime << std::endl;
std::cout << "sum = " << sum << std::endl;
}

- The compilation of the code takes roughly 14 seconds and when the code is profiled we can see that the main uses most of the % processing time. i.e., 99.93%.
