Device API for random number generator

[Weiqun_Z_]

Does oneAPI have GPU device API for random number generator?  I understand I can build an engine for a GPU device queue and call `mkl::rng::generate` on the host to generate a number of random numbers.  But I would like to be able to call a function to generate random numbers on the fly in a GPU device function.  Thanks!

Hi,

With oneMKL, using mkl::rng::generate, random number generation happens on the device(callable from host) but there's no device specific API as such to generate random numbers on the fly. 

We will escalate this to the concerned team as a feature request. Thanks for the question.
