warp.rand_init

warp.rand_init(seed: int32) → uint32

Kernel

Python

Initialize a random number generator.

Initialize from a user-defined seed.

Returns:

A 32-bit integer representing the RNG state.

warp.rand_init(seed: int32, offset: int32) → uint32

Kernel

Python

Initialize a random number generator.

Initialize from a user-defined seed and an offset.

This alternative constructor can be useful in parallel programs, where a kernel as a whole should share a seed, but each thread should generate uncorrelated values. In this case usage should be r = rand_init(seed, tid).
