Constructor & Destructor Documentation

Batches() [1/3]

Batches::Batches	(	RestrictArr	output,
		size_t	nEvents,
		const VarVector &	vars,
		const ArgVector &	extraArgs = {},
		double *	buffer = nullptr
	)

Construct a Batches object.

Parameters

output	The array where the computation results are stored.
nEvents	The number of events to be processed.
vars	A std::vector containing pointers to the variables involved in the computation.
extraArgs	An optional std::vector containing extra double values that may participate in the computation.
buffer	A 2D array that is used as a buffer for scalar variables. For every scalar parameter a buffer (one row of the buffer) is filled with copies of the scalar value, so that it behaves as a batch and facilitates auto-vectorization. The Batches object can be passed by value to a compute function to perform efficient computations.
