Dear all,
I am trying to generate an array of 1000 random numbers.
#include <cuda.h>
#include <cutil_inline.h>
#include “MersenneTwister.h”
#include “MersenneTwister_kernel.cu”
//ceil(a / b)
extern “C” int iDivUp(int a, int b){
return ((a % b) != 0) ? (a / b + 1) : (a / b);
}
//floor(a / b)
extern “C” int iDivDown(int a, int b){
return a / b;
}
//Align a to nearest higher multiple of b
extern “C” int iAlignUp(int a, int b){
return ((a % b) != 0) ? (a - a % b + b) : a;
}
//Align a to nearest lower multiple of b
extern “C” int iAlignDown(int a, int b){
return a - a % b;
}
int main(){
int N = 1000;
const int N_PER_RNG = iDivUp(N, MT_RNG_COUNT);
seedMTGPU(777);
float Rand_d;
cudaMalloc((void **) &Rand_d, Nsizeof(float));
RandomGPU<<<32, 128>>>(Rand_d, N_PER_RNG);
}
However, all the elements of Rand_d are the same. Am I doing something wrong? Thanks for the help.
