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.

Most of the time (99.3%) is spent executing the SaveImage function (Imager::Scene::SaveImage(char const*, unsigned long, unsigned long, double, unsigned long) const). In the additional lodepng code that runs alongside the ray tracer, 94.4% of time is spent in the CalculateLighting function (Imager::Scene::CalculateLighting(Imager::Intersection const&, Imager::Vector const&, double, Imager::Color, int) const).
