Function Documentation

collectSendIndices()

real Gravity::Kernel::Launch::collectSendIndices	(	Tree *	tree,
		Particles *	particles,
		integer *	sendIndices,
		integer *	particles2Send,
		integer *	pseudoParticles2Send,
		integer *	pseudoParticlesLevel,
		integer *	particlesCount,
		integer *	pseudoParticlesCount,
		integer	n,
		integer	length,
		Curve::Type	curveType
	)

Collect the send indices.

Collect the previous marked indices to be sent by copying to contiguous memory in order to send the particles or rather particle entries using MPI.

The function copies the (pseudo-)particles to contiguous memory as preparation for the communication process via MPI. Particles and pseudo-particles are copied to distinct buffers and are distinguishable by checking the index of the node.

Parameters

	tree	Tree class instance.
	particles	Particles class instance.
	sendIndices	Marked as to be sent or not.
[out]	particles2Send	Particles to be sent.
[out]	pseudoParticles2Send	Pseudo-particles to be sent.
[out]	pseudoParticlesLevel	Pseudo-particles level(s) (to be sent).
	particlesCount	Particles to be sent counter.
	pseudoParticlesCount	Pseudo-particles to be sent counter.
	n
	length
	curveType	Space-filling curve type.
