Keyword descriptions

FORCE_BLOCKSIZE: logical = F

Lone keyword: T

Usage: FORCE_BLOCKSIZE

Forces the blocksize, even if this implies that a few processes might have no data [Edit on GitHub]

GRID_2D: integer[2] = 1 1

Usage: GRID_2D 64 16

Explicitly set the blacs 2D processor layout. If the product differs from the number of MPI ranks, it is ignored and a default nearly square layout is used. [Edit on GitHub]

K: integer = 256

Usage: A 1024

Dimension 1 of C [Edit on GitHub]

M: integer = 256

Usage: A 1024

Inner dimension M [Edit on GitHub]

N: integer = 256

Usage: A 1024

Dimension 2 of C [Edit on GitHub]

NCOL_BLOCK: integer = 32

Usage: nrow_block 64

N_LOOP: integer = 10

Usage: N_LOOP 10

Number of cp_fm_gemm operations being timed (useful for small matrices). [Edit on GitHub]

Usage: ROW_MAJOR .FALSE.

Use a row major blacs grid [Edit on GitHub]

TRANSA: logical = F

Lone keyword: T

Usage: TRANSA
