Cuda

Simple CUDA example (experimental)

shared.h

struct WTGPos {

    float x = 0;

    float y = 0;

};

Cuda.cpp

#include <Core/Core.h>

#include "shared.h"

using namespace Upp;

void cuda_mul_a(float a, float *x, int count);

CONSOLE_APP_MAIN

{

    StdLogSetup(LOG_COUT|LOG_FILE);

    Vector<float> x;

    for(float i = 0; i < 10; i++)

        x << i;

    DDUMP(x);

    cuda_mul_a(10, x.begin(), x.GetCount());

    DDUMP(x);

    x.Clear();

    for(int i = 0; i < 123456780; i++)

        x << (float)i;

    auto xx = clone(x);

    for(float& m : xx)

        m *= 13;

    cuda_mul_a(13, x.begin(), x.GetCount());

    ASSERT(x == xx);

}
