WebSep 12, 2024 · CURAND library doesn't work inside it (pyCUDA). Since, there is lot of work to be done in GPU, generating random number inside CPU and then transferring them to GPU won't work, rather dissolve the motive of using GPU. Supplementary Questions: Is there a way to allocate memory on GPU using 1 block and 1 thread. I am using more … WebMar 15, 2014 · curand_init (clock64 (), i, 0, &state); EDIT Following Roger Dahl's comment, I have done a comparison (Kepler K20c) between four different possibilities for the generation of arrays of 131072 elements: Single random number generation: separate kernels for initialization and random number generation;

This gives you more power to control what’s going on and perhaps use the generated random numbers without ever having to write them to memory. But it’s more complicated. dfs bank investor relations https://fritzsches.com

Many thanks! – waynelee1217 Mar 24, 2014 at 14:47 WebJul 6, 2015 · You're running init each time you ask for a random value. Instead you should run curand_init () once, in a separate kernel at the start of your code. Then when you want a new random value, just call curand_normal (). Then the values will change each time you call your device function. For an example see my answer here.

In device code, it is designed to return one or a small number of random numbers per thread. The thread's random generators run independently of each other, and it is usually advised for performance reasons to give each thread a different seed, rather than a different offset.
