curandGenerateNormalDouble usage Not working with large sample size

Accelerated Computing CUDA CUDA Programming and Performance

Hi,

In the code below, the call to curandGenerateNormalDouble is failing as it is not returning the Success status.

If I change the 125000 to a smaller value, it runs okey. Is there a limitation of the curandGenerateNormalDouble function.

If I use curandGenerateUniformDouble, it runs okey.

If it is timeout, how could it fix it?

The card we have is GTX295 and running on windows server 2008.

cudaResult = cudaMalloc((void **)&data, 125000 * sizeof(double)); 

for (unsigned int i = 0; i <= 1000000 ; i++) 

{ 

      curandResult = curandGenerateNormalDouble(gen, data, 125000, mean, stddev);

}

Thanks
