Method Detail

computeChunkShape

public int[] computeChunkShape(long maxChunkElems)

Computes the shape of the largest possible contiguous chunk, starting at Index.getCurrentCounter() and with numElems <= maxChunkElems.

Parameters:

maxChunkElems - the maximum number of elements in the chunk shape. The actual element count of the shape returned is likely to be different, and can be found with Index.computeSize(int[]).

Returns:

the shape of the largest possible contiguous chunk.
