The ----llllssssccccssss____mmmmpppp option directs the linker to use the multi-processor version of the library. When linking to SCSL with ----llllssssccccssss or ----llllssssccccssss____mmmmpppp, the default integer size is 4 bytes (32 bits). Another version of SCSL is available in which integers are 8 bytes (64 bits). This version allows the user access to larger memory sizes and helps when porting legacy Cray codes. It can be loaded by using the ----llllssssccccssss____iiii8888 option or the ----llllssssccccssss____iiii8888____mmmmpppp option. A program may use only one of the two versions; 4-byte integer and 8-byte integer library calls cannot be mixed. The C and C++ prototypes shown above are appropriate for the 4-byte integer version of SCSL. When using the 8-byte integer version, the variables of type iiiinnnntttt become lllloooonnnngggg lllloooonnnngggg and the <<<<ssssccccssssllll____bbbbllllaaaassss____iiii8888....hhhh>>>> header file should be included.

ZZZZAAAAXXXXPPPPBBBBYYYY: Double precision complex array. The vector _x. If _i_n_c_x > 0, the _i-th element of the vector _x is located in _x(1+(_i-1) * |_i_n_c_x|). If _i_n_c_x < 0, the _i-th element of the vector _x is located in _x(1+(_n-_i) * |_i_n_c_x|). _i_n_c_x Integer. (input) Increment between elements of the vector _x. If _i_n_c_x < 0, _x is processed in reverse order. _b_e_t_a Scalar beta. (input) SSSSAAAAXXXXPPPPBBBBYYYY: Single precision scalar. DDDDAAAAXXXXPPPPBBBBYYYY: Double precision scalar. CCCCAAAAXXXXPPPPBBBBYYYY: Single precision complex scalar. ZZZZAAAAXXXXPPPPBBBBYYYY: Double precision complex scalar.

If _i_n_c_y < 0, the _i-th element of the vector _y is located in _y(1+(_n-_i) * |_i_n_c_y|). On exit, _y is overwritten with the vector ssssuuuummmm _a_l_p_h_a_x+ _b_e_t_a_y. _i_n_c_y Integer.
