Function Documentation

template<int numComponentsPerElement>

static void clearBufferFlagged	(	const nbnxn_atomdata_t &	nbat,
		int	outputIndex,
		gmx::ArrayRef< real >	buffer
	)

static

Clears elements of size and stride numComponentsPerElement.

Only elements with flags in nbat set for index outputIndex are cleared.

Clears the force buffer.

Either the whole buffer is cleared or only the parts used by thread/task outputIndex when nbat->bUseBufferFlags is set.

Parameters

[in,out]	nbat	The Nbnxm atom data
[in]	outputIndex	The index of the output object to clear
