Member Function Documentation

allocate()

void LatinHyperCube::allocate ( const CmdArguments_t &  , const Comm::Bundle_t &    )

inlinevirtual

Allocate memory for sampling. Not every sampling method requires that.

This function is used to reduce memory since only the sampler ranks need these sampling methods.

Parameters

args	samler arguments
comm	sampler communicator

Reimplemented from SamplingMethod.
