Detailed Description

Ordering of indices when a BlockXD is converted into a serial data stream.

Signification of constants:

• forward: Right-most index (y in 2D and z in 3D) is contiguous in memory. For non-allocated parts of the Block, the value 0 is produced for output, and values are ignored during input.
• backward: Left-most index (x) is contiguous in memory. For non-allocated parts of the Block, the value 0 is produced for output, and values are ignored during input.
• memorySaving: Ordering is forward (this respects the natural ordering in Palabos). Non-allocated parts of the Block are neither written or read: memory savings in the program are reflected by memory savings on the disk.
