pdgemm_ algorithm

[mvairavan]

I have been using pdgemm_ scalapack function call for matrix multiplication. I am using square matrix and a square grid of processors.
And figured out that its calling PB_CpgemmAB function call, which says its "outer-product algorithm using the logical LCM hybrid algorithmic blocking technique".
Can anyone tell me whats the algorithm used in this call. Is it SUMMA or DIMMA ??

Thanks.

PBLAS matrix multiplication (included in ScaLAPACK library) is based on the SUMMA algorithm.
Hope it helps
