Assignment 1
Our group decided to profile a couple of different solutions, the first being a simple neural network and ray tracing solution, in order to determine the best project to generate a solution for.
Neural Network
Sebastian's findings
I found a simple neural network that takes a MNIST data set and preforms training on batches of the data. For a quick illustration MNIST is a numerical data set that contains many written numbers --in a gray scale format at 28 x 28 pixels in size. As well as the corresponding numerical values; between 0 and 9. The reason for this data set is to train networks such that they will be able to recognize written numbers when they confront them.

After the initial profile it is obvious that the dot product function consumes 97.94% of our run time. Additionally, the transpose function also consumes 1.45% which seems messily, however during back propagation transpose is also called, as well as two rectifiers(activation functions), reluPrime and relu. Where reluPrime is a binary activation function.
Relu = f(x) = {0 for x > 0, x otherwise}
ReluPrime = f(x) = {0 for x > 0, 1 otherwise}
Code Snippets
// Back propagation
vector<float> dyhat = (yhat - b_y);
// dW3 = a2.T * dyhat
vector<float> dW3 = dot(transpose( &a2[0], BATCH_SIZE, 64 ), dyhat, 64, BATCH_SIZE, 10);
// dz2 = dyhat * W3.T * relu'(a2)
vector<float> dz2 = dot(dyhat, transpose( &W3[0], 64, 10 ), BATCH_SIZE, 10, 64) * reluPrime(a2);
// dW2 = a1.T * dz2
vector<float> dW2 = dot(transpose( &a1[0], BATCH_SIZE, 128 ), dz2, 128, BATCH_SIZE, 64);
// dz1 = dz2 * W2.T * relu'(a1)
vector<float> dz1 = dot(dz2, transpose( &W2[0], 128, 64 ), BATCH_SIZE, 64, 128) * reluPrime(a1);
// dW1 = X.T * dz1
vector<float> dW1 = dot(transpose( &b_X[0], BATCH_SIZE, 784 ), dz1, 784, BATCH_SIZE, 128);
vector <float> dot (const vector <float>& m1, const vector <float>& m2, const int m1_rows, const int m1_columns, const int m2_columns) {
vector <float> output (m1_rows*m2_columns);
for( int row = 0; row != m1_rows; ++row ) {
for( int col = 0; col != m2_columns; ++col ) {
output[ row * m2_columns + col ] = 0.f;
for( int k = 0; k != m1_columns; ++k ) {
output[ row * m2_columns + col ] += m1[ row * m1_columns + k ] * m2[ k * m2_columns + col ];
}
}
}
return output;
}
Amdahl's law
When Amdahl's law is applied the theoretical speed up is 48.54x, however due to the exception the actual prediction is no more then 10x faster.
Theoretical:
s = 1/(1 - 97.94%) = 1/(1 - 0.9794) = 48.54
Prediction:
P = 102s
Possible complications
The main concern when parallelizing these code snippets is that memory copying is going to take up a lot of time, so despite the predicted speed up, there is no certain answer until the Cuda kernel is complete.
Hypothesis
Our Hypothesis for this solution is a acceleration of roughly 10x; when dot() is parallelized. This means that our code should take somewhere in the ball park of 102 seconds to train the network.
Ray Tracing
Henry's findings
I decided to choose a ray tracing program that draws graphics such as a block, cuboid and cylinder. The shapes are rendered with shadows. The program is from http://cosinekitty.com/raytrace.

Assignment 2
During assignment 2, we tried a simple kernel that took the shape of a dot product, what this achieved was nothing special, actually as predicted at the end of assignment 1, continuously calling cudaMalloc and cudaMemCpy had severe consequences on time.
Initial implementation
//version 1 dot product
__global__ void kdot(const float* d_a, const float* d_b, float* d_p, int ni, int nj, int nk) {
int i = blockIdx.x * blockDim.x + threadIdx.x;
int j = blockIdx.y * blockDim.y + threadIdx.y;
//matrix multiplication
if (i < ni && j < nj) {
float sum = 0.0f;
for (int k = 0; k < nk; k++)
sum += d_a[i * nk + k] * d_b[k * nj + j];
d_p[i * nj + j] = sum;
}
}
Naive
Naturally this is a naive implementation as we are calling cudaMalloc for each iteration of the training for loop.
cout << "Training the model ...\n";
for (unsigned i = 0; i < 10000; ++i) {
This actually costs us an additional 20 minutes when profiling could be done.
The next steps
Well firstly we had to engage in research as to understand how the actual neural network was learning; for example why they used relu() function, how back-propagation worked and so much more. Some additional sites will be included.
After that and many coffees!

// Updating the parameters

for (int i = 0; i < (64*10); i++) {
d_W3[i] = d_W3[i] - lr * d_dW3[i];

Dynamic Parallelism
Dynamic Parallelism in CUDA allows for the support of kernels to create and synchronize new nested kernels. Additionally, for our use case it also allows us to spend more time on the device to process information quickly without constant cudaMemcpy() or cudaMalloc() calls.
