GEMM은 무엇일까?

 GEneral Matrix to Matrix Multiplication

multiplies two input matrices together to get an output one

C := alpha*op(A)*op(B) + beta*C,

scalar-matrix-matirx product 

op(X) is one of op(X) = X, or op(X) = XT, or op(X) = XH,

alpha and beta are scalars,

A, B and C are matrices:

op(A) is an m-by-k matrix,

op(B) is a k-by-n matrix,

C is an m-by-n matrix.
