      List of main options that can be used in timing:
-     * ~--help~: show usage
-     * ~--threads~: Number of CPU workers (default:
-       ~_SC_NPROCESSORS_ONLN~)
-     * ~--gpus~: number of GPU workers (default: ~0~)

-     * ~--m=X~: dimension (M) of the matrices (default: ~N~)
-     * ~--k=X~: dimension (K) of the matrices (default: ~1~), useful for
-       GEMM algorithm (k is the shared dimension and must be defined
-       >1 to consider matrices and not vectors)
