• Keyword descriptions

  K
  	A 1024
  	Dimension 1 of C
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 256

  M
  	A 1024
  	Inner dimension M
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 256

  N
  	A 1024
  	Dimension 2 of C
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 256

  NCOL_BLOCK
  	NROW_BLOCK 64
  	block_size for cols
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 32

  NROW_BLOCK
  	NROW_BLOCK 64
  	block_size for rows
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 32

  N_LOOP
  	N_LOOP 10
  	Number of cp_fm_gemm operations being timed (useful for small matrices).
  	This optional keyword cannot be repeated and it expects precisely one integer.
  	Default value: 10

  TRANSA
  	TRANSA
  	Transpose matrix A
  	This optional keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.

  TRANSB
  	TRANSB
  	Transpose matrix B
  	This optional keyword cannot be repeated and it expects precisely one logical.
  	The lone keyword behaves as a switch to .TRUE.
  	Default value: .FALSE.
