executeSerialMerge

public MatrixObject executeSerialMerge()

Description copied from class: ResultMerge

Merge all given input matrices sequentially into the given output matrix. The required space in-memory is the size of the output matrix plus the size of one input matrix at a time.

Specified by:

executeSerialMerge in class ResultMerge

Returns:

output (merged) matrix

executeParallelMerge

public MatrixObject executeParallelMerge(int par)

Description copied from class: ResultMerge

Merge all given input matrices in parallel into the given output matrix. The required space in-memory is the size of the output matrix plus the size of all input matrices.

Specified by:

executeParallelMerge in class ResultMerge

Parameters:

par - degree of parallelism

Returns:

output (merged) matrix
