Class ov::reference::philox::PhiloxGenerator

class PhiloxGenerator

Generator of random numbers based on the Philox algorithm. Abstract base class for various specializations used to match outputs based on input seed(s) for supported frameworks.

Subclassed by ov::reference::philox::MockPhiloxGenerator, ov::reference::philox::PytorchPhiloxGenerator, ov::reference::philox::TensorflowPhiloxGenerator

Public Functions

virtual PhiloxOutput random() = 0

Get a set of 4 random 32-bit unsigned integers based on the seed(s).

Returns:

A vector with a random set of 4 32-bit unsigned integers.

virtual std::pair<uint64_t, uint64_t> get_next_state() = 0

Returns the modified state to feed to the next execution.

Returns:

A pair of uint64s that represent the output state to be fed to the next generator execution.

uint64_t get_global_seed() const

Returns the global seed of the generator.

uint64_t get_operator_seed() const

Returns the operator seed of the generator.

ov::op::PhiloxAlignment get_alignment() const

Returns the alignment mode of the generator.

std::pair<uint64_t, uint64_t> get_previous_state() const

Returns the input (previous execution) state of the generator.

void set_global_seed(const uint64_t global_seed)

Setter for the global seed.

Parameters:

global_seed – The new global seed for the Philox algorithm

void set_operator_seed(const uint64_t op_seed)

Setter for the operator seed.

Parameters:

op_seed – The new operator seed for the Philox algorithm
