Function Documentation

◆ forAllCellPairs()

template<ExecTag XTag, CellPairFunction Func>

void walberla::v8::sweep::forAllCellPairs	(	XTag	xtag,
		const CellInterval &	firstCi,
		const CellInterval &	secondCi,
		Func	func )

inline

Run an operation for every pair of cells in the given intervals.

Iterates the given cell intervals sequentially and in lockstep in z-y-x order (x is the fastest, z the slowest coordinate) and calls func for every pair of cells.

Exceptions

std::invalid_argument In debug mode, throws if the given cell intervals are of different size.

◆ forAllCells()

template<ExecTag XTag, CellFunction Func>

void walberla::v8::sweep::forAllCells	(	const XTag &	exTag,
		const StructuredBlockForest &	blocks,
		Func &&	func )

Invoke forAllCells on the default per-block cell interval.

◆ sync()

void walberla::v8::sweep::sync ( )

inline

Synchronize with concurrent execution on the default stream.

When running with a GPU programming model, wait for currently active work on the primary stream or queue is finished.

Note: This function only waits for executions dispatched on a default-constructed exectag::GPU.; When no GPU back-end is enabled, this function may still safely be called, but will do nothing
