Curand_init
WebMay 31, 2011 · Putting the curand_init into a separate kernel allowed me to increase the number of trials by a couple orders of magnitude. Also I create a separate state array for y with a different seed value and curand_init call. This increased the runtime a little but gave me at least 1 extra digit than how it was earlier. Although it seems this monte ... WebMar 24, 2014 · So does it mean that the following argument should work? device void curand_init (unsigned long long seed, unsigned long long sequence, unsigned long long offset, curandState_t *state)__device__ float curand_normal (curandState_t *state) Or should I add more things here? Many thanks! – waynelee1217 Mar 24, 2014 at 14:47
