Message

A different random number generator is used. You may need to adjust the code.

Detailed Help

Intel® oneAPI Math Kernel Library (oneMKL) RNG currently does not support the following engine types:

XORWOW generator
Sobol generator of 64-bit sequences
Scrambled Sobol generator

The engine types are migrated to the following supported generators, respectively:

MCG59 generator
Basic Sobol generator
Basic Sobol generator

Suggestions to Fix

You may need to adjust the code.

For example, this original CUDA* code:

 __global__ void kernel(curandStateXORWOW_t rng) {
   ...
 }

results in the following migrated SYCL* code:

 /*
 DPCT1032:0: A different random number generator is used. You may need to adjust
 the code.
 */
 void kernel(
     dpct::rng::device::rng_generator<oneapi::mkl::rng::device::mcg59<1>> rng) {
   ...
 }

which is rewritten to:

 void kernel(
     dpct::rng::device::rng_generator<oneapi::mkl::rng::device::mcg59<1>> rng) {
   ...
 }
