Detailed Description

Module: CLA_Matrix Purpose: dense matrix-matrix multiplication.

Usage:

• To create the arrays, use the make_multiplier call detailed in CLA_Matrix.h.

• To multiply once you have the CLA_Matrix_interface object o, do this: o.multiply(alpha, beta, data, fptr, usr_data, thisIndex.x, thisIndex.y)

  Note: When mentioning which parameters below are used, we refer only to the 2D algorithm. Notes for the 3D algorithm will be added later.

  Alpha and beta should be doubles. Only the alpha and beta passed to the C array will be used. Data should be a double* pointing to the data to be multiplied if we are at the chare array bound to the A or B arrays. Otherwise (we are at C), it should be the location where to store the result. We need to pass the index since we will use ckLocal calls. Once the multiplication has finished, the C array will call to function pointed to by fptr, passing it usr_data. These arguments will be ignored by A and B. fptr should take a void* as an argument are return void.
