i downloaded the fann library written by seth that runs on GPU.
http://leenissen.dk/fann/forum/viewtopic.php?f=2&t=658
i am running ubuntu, opengl, glut on nvidia graphics card. i tried to compile with fann_gpu.h and hit a brick wall here.
Here is the example code
gpu.c
include "fann/src/gpu/fann_gpu.h"
layer *A, *B, *C, *D, *E;
float *input, *weight_matrix, *mask_matrix;
int i,j;
double start, end, run_time;
//Dummy function for filling weights and mask with dummy data, it preserves the texture sizes wich is multiples of 4.
void fillWeights(layer *target);
//dummy vector data
void fillVector(layer *target);
int main(int argc, char *arg){
char error;
int n = 5;
//start OpenGL
initOpenGL();
//testing system compatibility
if ((error = test()) != 0){
printf("Error: %s\n", error);
return -1;
}
//initializing system.
if (!init()){
printf("Init not successful...");
return -1;
}
//create layers using the sigmoid_sum fragment program.
A = generateLayer("sigmoid_sum_masked.fp", 4, 40, 0);
B = generateLayer("sigmoid_sum_masked.fp", 40, 16, 0);
C = generateLayer("sigmoid_sum_masked.fp", 40, 22, 16);
D = generateLayer("sigmoid_sum_masked.fp", 38, 5, 0);
E = generateLayer(0, 5, 0, 0);
setOutput(A, B);
setInput(C, A);
setOutput(B, D);
setOutput(C, D);
setOutput(D, E);
//dummy values.
//fill vectors with values.
fillWeights(A);
copyWeightsToTexture(weight_matrix, A);
copyMaskToTexture(mask_matrix, A);
free(weight_matrix);
free(mask_matrix);
fillWeights(B);
copyWeightsToTexture(weight_matrix, B);
copyMaskToTexture(mask_matrix, B);
free(weight_matrix);
free(mask_matrix);
fillWeights(C);
copyWeightsToTexture(weight_matrix, C);
copyMaskToTexture(mask_matrix, C);
free(weight_matrix);
free(mask_matrix);
fillWeights(D);
copyWeightsToTexture(weight_matrix, D);
copyMaskToTexture(mask_matrix, D);
free(mask_matrix);
free(weight_matrix);
//Execute the network n times.
while (n-->0){
fillVector(A);
copyVectorToTexture(input, A);
run(A);
run(B);
run(C);
run(D);
printLayer(E);
free(input);
}
//clean up
destroyLayer(A);
destroyLayer(B);
destroyLayer(C);
destroyLayer(D);
destroyLayer(E);
return 0;
}
//Dummy function for filling weights and mask with dummy data, it preserves the texture sizes wich is multiples of 4.
void fillWeights(layer *target){
weight_matrix = calloc(target->out_size * target->size, sizeof(float));
mask_matrix = calloc(target->out_size * target->size, sizeof(float));
for(i=0; iout_size; i++){
for(j=0; jsize; j++){
weight_matrix[j+i_target->size] = RAND_UNI;
//weight_matrix[j+i_target->size] = j+i_target->size;
//weight_matrix[j+i_target->size] = 1.0f;
mask_matrix[j+i*target->size] = 1;
}
}
}
//dummy vector data
void fillVector(layer _target){
input = malloc(sizeof(float)_target->size);
for(i=0; isize; i++){
input[i] = RAND_UNI;
//input[i] = i;
//input[i] = 1;
}
}
compiling this file gives this.. Am i missing something here?
