Detailed Description

Thread-safe random engine for OpenMP threads

Each thread owns its private sub- random engine, and calls to OpenMPRandomEngine is lock-free

For debugging with deterministic psudo random numbers, just ensure two things:

The seed is deterministic
Tasks are distrubuted to threads in a deterministic way (parallel for schedule(static))

Member Typedef Documentation

◆ result_type

typedef RNG::result_type freetensor::OpenMPRandomEngine::result_type

sub-engines for each thread

Constructor & Destructor Documentation

◆ OpenMPRandomEngine() [1/3]

freetensor::OpenMPRandomEngine::OpenMPRandomEngine ( RNG::result_type seed )

Requried by STL, but not enforced in std::uniform_random_bit_generator

◆ OpenMPRandomEngine() [2/3]

freetensor::OpenMPRandomEngine::OpenMPRandomEngine ( const OpenMPRandomEngine & )

delete

Disable copy so we won't accidentally repeat some sequences

◆ OpenMPRandomEngine() [3/3]

freetensor::OpenMPRandomEngine::OpenMPRandomEngine ( OpenMPRandomEngine && )

default

◆ max()

static constexpr RNG::result_type freetensor::OpenMPRandomEngine::max ( )

◆ min()

static constexpr RNG::result_type freetensor::OpenMPRandomEngine::min ( )

inlinestaticconstexpr

◆ operator()()

OpenMPRandomEngine::RNG::result_type freetensor::OpenMPRandomEngine::operator() ( )

◆ operator=() [1/2]
