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.

DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN These routines perform the following Hermitian rank 1 operation: _A <- _a_l_p_h_a _x_x_H + _A where _a_l_p_h_a is a real scalar, _x is an _n-element vector, _x_H is the conjugate transpose of _x, and _A is an _n-by-_n packed complex Hermitian matrix. See the NOTES section of this man page for information about the interpretation of the data types described in the following arguments. These routines have the following arguments: _u_p_l_o Character. (input) Specifies whether the upper or lower triangular part of matrix _A is packed into the array argument _a_p, as follows: _u_p_l_o= 'U' or 'u': the upper triangular part of _A is supplied in the argument _a_p. _u_p_l_o= 'L' or 'l': the lower triangular part of _A is supplied in the argument _a_p. _n Integer. (input) Specifies the order of matrix _A. _n >= 0. _a_l_p_h_a Scalar alpha. (input) CCCCHHHHPPPPRRRR: Real. ZZZZHHHHPPPPRRRR: Double precision. _x Array of dimension 1+(_n-1) * |_i_n_c_x|. (input) CCCCHHHHPPPPRRRR: Single precision complex array. ZZZZHHHHPPPPRRRR: Double precision complex array. Contains vector _x. _i_n_c_x Integer. (input) Specifies the increment for the elements of _x. _i_n_c_x must not be 0. _a_p Array of dimension (_n(_n+1))/2 . (input and output) CCCCHHHHPPPPRRRR: Single precision complex array. ZZZZHHHHPPPPRRRR: Double precision complex array. Before entry with _u_p_l_o = 'U' or 'u', array _a_p must contain the upper triangular part of the Hermitian matrix packed sequentially, column-by-column, so that _a_p(1) contains _A(1,1), _a_p(2) contains _A(1,2), _a_p(3) contains _A(2,2), and so on. On PPPPaaaaggggeeee 2222 CCCCHHHHPPPPRRRR((((3333SSSS)))) CCCCHHHHPPPPRRRR((((3333SSSS)))) exit, the upper triangular part of the updated matrix overwrites array _a_p. Before entry with _u_p_l_o = 'L' or 'l', array _a_p must contain the lower triangular part of the Hermitian matrix packed sequentially, column-by-column, so that _a_p(1) contains _A(1,1), _a_p(2) contains _A(2,1), _a_p(3) contains _A(3,1), and so on. On exit, the lower triangular part of the updated matrix overwrites array _a_p. The imaginary parts of the diagonal elements need not be set. They are assumed to be 0; on exit, they are set to 0. NNNNOOOOTTTTEEEESSSS CCCCHHHHPPPPRRRR/ZZZZHHHHPPPPRRRR is a Level 2 Basic Linear Algebra Subprogram (Level 2 BLAS).
