Tile Size (NB) and Inner Block Size (IB) question

Postby zcosmos » Thu Nov 29, 2012 10:01 pm

Hi,

I have a quick question regarding the NB and IB parameters passed to the "PLASMA_Set(PLASMA_TILE_SIZE, NB)" and "PLASMA_Set(PLASMA_INNER_BLOCK_SIZE, IB)" functions.

Does the NB parameter indicate the size of each tile? i.e., NB=4 means the matrix will be broken up into several tiles each being 4 by 4 elements.

Or does it indicate how many tiles we want the matrix to be divided into? i.e. NB=4 means there will be 4 squared tiles regardless of the matrix size.

Similarly for the IB parameter, and given the constraint that IB cannot be larger than NB, does IB indicate the size of each inner block or does it indicate how many blocks we want per NB?

Thank you so much for your help! :)
