ENH: kernels for `random.vonmisses`; part 2

[samir-nasibli]

Description

Enable computations on devices [CPU/GPU].

Tests

• DPNP own:

tests/test_random.py::TestDistributionsVonmises::test_moments[large_kappa] PASSED
tests/test_random.py::TestDistributionsVonmises::test_moments[small_kappa] PASSED

tests/test_random.py::TestDistributionsVonmises::test_seed[large_kappa] FAILED
tests/test_random.py::TestDistributionsVonmises::test_seed[small_kappa] FAILED

• + numpy external

TODO

tests/test_random.py::TestDistributionsVonmises::test_seed failed on both devices. Bug.

@LukichevaPolina The use of extra memory with the amount of data is not a good practice in optimization. We must avoid this cases. We have to remove the possibilities for a potential race condition in the algorithm.

1. Any optimization with the use of additional memory can actually degrade (depending on the input data) and underestimate all the benefits from parallelism. Allocation/Deallocation/Working with additional memory is expensive.

2. We have to remove the possibilities for a potential race condition in the algorithm. - done

using extra mem is brute force approach.

3. - ideas?

We need to investigate it.

4. I also recommend to use perf tests and profiler tools during optimization. Comparative analysis is important in such work.
