### Assignment 1

#### Sudoku Puzzle Solver by Gurpreet Singh

Is it a program that solves Sudoku puzzles(9X9) using Bruteforce algorithm. The user can either pass a Sudoku files as an input or enter the values manually. Moreover, the file or the manual entry must strictly have 9 rows and 9 columns in them. Last but not the least, all the cells must be separated by a space and the cells that needs to be solved must have 0 in them as their value.

The original source code can be found at Link

##### Logic

In this program the Bruteforce algorithm first put 1 in the first cell. Then it moves to the second cell and put 1 in there and check if it satisfies all the rules and conditions. If it don't, then the algorithm will increment it's value to 2 and then check again. The value can change from 0-9 to find the correct value for a cell. If none of the value from the range of 0-9 satisfies the cell, then the program will iterate back and change the value of the first cell to 2 and then try the whole process again. In this way it will solve the puzzle.

##### Compiling the program

Enter the following commands:

g++ -std=c++0x -pg solver.cpp checks.cpp checksolution.cpp -o a
a fileName

-pg directs the compiler to include the executable code required for profiling.

-o directs the compiler to name the executable a.

If we run the sample-puzzle-1 (level- easy) file, which has the following text inside it:

0 6 0 0 0 0 9 7 2
0 5 0 0 0 2 0 0 3
0 7 0 3 9 0 5 0 0
2 0 0 0 0 5 4 0 8
0 0 0 0 0 0 0 0 0
3 0 1 8 0 0 0 0 6
0 0 4 0 2 3 0 8 0
7 0 0 9 0 0 0 2 0
9 2 5 0 0 0 0 4 0

The output will be:

1 6 3 4 5 8 9 7 2
4 5 9 7 1 2 8 6 3
8 7 2 3 9 6 5 1 4
2 9 7 1 6 5 4 3 8
5 8 6 2 3 4 1 9 7
3 4 1 8 7 9 2 5 6
6 1 4 5 2 3 7 8 9
7 3 8 9 4 1 6 2 5
9 2 5 6 8 7 3 4 1

##### Analysis

To analyze the call graph, enter the following command:

gprof -q -b a> a.clg

-q directs the profiler (gprof) to output a call graph.

-b directs the profiler to omit detailed explanations of the column headings from the output.

The call graph for the above execution looks like:

[11] checkSquare(int, int, int) [19] __static_initialization_and_destruction_0(int, int) [10] placeNum(int, int)

From the above Call graph we can see that the program took no time in finding the solution and the maximum number of calls were made to the checkRow, checkColumn and checkSquare function. However, to get a better understanding of the program let's try a harder Sudoku puzzle.

If we run the sample-puzzle-2-hard (Level- hard) file, which has the following text inside it:

0 0 0 0 0 0 0 0 0
0 0 0 0 0 3 0 8 5
0 0 1 0 2 0 0 0 0
0 0 0 5 0 7 0 0 0
0 0 4 0 0 0 1 0 0
0 9 0 0 0 0 0 0 0
5 0 0 0 0 0 0 7 3
0 0 2 0 1 0 0 0 0
0 0 0 0 4 0 0 0 9

The output will be:

9 8 7 6 5 4 3 2 1
2 4 6 1 7 3 9 8 5
3 5 1 9 2 8 7 4 6
1 2 8 5 3 7 6 9 4
6 3 4 8 9 2 1 5 7
7 9 5 4 6 1 8 3 2
5 1 9 2 8 6 4 7 3
4 7 2 3 1 9 5 6 8
8 6 3 7 4 5 2 1 9

The Call graph for the following looks like:

From the above Call graph we can see that for a harder Sudoku puzzle, the time increased significantly. Moreover, it can also be seen that almost 50% of the time is consumed by the checkRow function, 18.8% by checkColumn and finally 12% by the checkSquare function. Thousand of calls were made to these 3 functions, if we parallelizing these functions then the efficiency of the program can be increased significantly.

#### Simple Artificial Neural Network by Sukhbeer

##### Introduction

I am very interested in neural networks and I started learning about them recently. I think this is a good opportunity to build on my knowledge of a NN while also parallelising it. For that purpose, I have selected a very basic neural network which feeds forward with ReLu and softmax and back-propagates on a sample batch from MNIST handwritten digits dataset. In each iteration, the weights are adjusted to train the network for better predictions. The code performs matrix-multiplication(dot-product) each time that the activation vector and delta vector are calculated for the next node and the previous node respectively.

##### Source Code

Here is the source code used. The result given below is the comparison of predictions as made by the trained network after 10000 iterations. The ground truth is the actual value of the labels between 0-9 (true for the corresponding digit in the dataset).

##### Analysis

The total execution time of the program is around 10 minutes. As is evident from profiling results, most of the execution time is taken up by the dot() function as it does matrix-matrix multiplication. This is the hotspot of the program that can be made efficient by doing this computation and other vector multiplications on the GPU.

#### Sorting Algorithms - Merge Sort - Edgar Giang

##### Intro

The topic I chose is sorting algorithms. The algorithm that I'll be profiling and analyzing would be a merge sort algorithm written in c++ which can be found Here. This code would ask the user to input the size of the array and then fill the array with random elements. The size of the array can be extremely large. From the original creator, the size of the array entered was in the tens of thousands. Theoretically, there would be no limit to how much the user can input however the original creator of this code said it would take the user several hours to sort 10 million elements in the entered array.

### How to run the program

The following commands was tested in putty:

g++ fileName.cpp -pg -o test

./test

### Running the program

This would be the following output:

200000
unsorted
sorted
time: 166100

As you can see the input used was 200,000. The time indicated in the output is in milliseconds so it took 166100 milliseconds to complete. A much larger input would result in the program running for a very long time.

### Analysis

21.90      0.07     0.07   600021     0.00     0.00  int* std::__copy_move<false, true, std::random_access_iterator_tag>::__copy_m<int>(int const*, int const*, int*)
15.64      0.12     0.05   200006     0.00     0.00  merge(std::vector<int, std::allocator<int> >, unsigned int, unsigned int, unsigned int)

From the flat profile,the hotspots for this program would be the function merge function whih was called 200,006 times and thee int* std::__copy__move. The merge function would take up 52.3% of the time
