Detailed Description

Supplies reproducible MPI-aware random streams for collisions and sources.

The stream is seeded from ORB5X input and rank state, then consumed in marker order. Reproducibility therefore assumes the same backend, MPI decomposition, and particle ordering.

Fortran reference random_coll.F90, module random_coll.

Member Function Documentation

genere_random()

static void orb5x::RandomColl::genere_random ( std::vector< Real > &  rand, int  npart, int  choice  )

static

Fill rand with npart independent variates.

Parameters

[out]	rand	Resized/output random-number vector.
[in]	npart	Number of requested samples.
[in]	choice	1 standardized uniform, 2 standard normal, and—with CURAND support—3 device uniform or 4 device Gaussian.

init_random_coll()

static void orb5x::RandomColl::init_random_coll ( )

static

Parse/broadcast the configured seed and initialize the rank-local stream.
