accumulate()

void accumulate ( const RefVector< MCPWalker > &  walkers, const RefVector< ParticleSet > &  psets, const RefVector< TrialWaveFunction > &  wfns, const RefVector< QMCHamiltonian > &  hams, RandomBase< FullPrecRealType > &  rng  )

inlineoverridevirtual

Accumulate whatever it is you are accumulating with respect to walkers.

This method is assumed to be called from the crowd context It provides parallelism with respect to computational effort of the estimator without causing a global sync. Depending on data locality the accumlation of the result may be different from the single thread write directly into the OperatorEstimator data.

Parameters

[in]	walkers
[in,out]	pset_target	crowd scope target pset (should be returned to starting state after call)
[in]	psets	per walker psets
[in]	wnfs	per walker TrialWaveFunction
[in,out]	rng	crowd scope RandomGenerator

Implements OperatorEstBase.
