- These routines are part of the SCSL Scientific Library and can be loaded
- using either the -lscs or the -lscs_mp option. The -lscs_mp option
- directs the linker to use the multi-processor version of the library.
-
- When linking to SCSL with -lscs or -lscs_mp, 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 -lscs_i8 option or the -lscs_i8_mp option. A program may use
- only one of the two versions; 4-byte integer and 8-byte integer library
- calls cannot be mixed.

- SCSUM1 takes the sum of the absolute values of a complex vector and
- returns a single precision result. Based on SCASUM from the Level 1 BLAS.
- The change is to use the 'genuine' absolute value.

- N (input) INTEGER
- The number of elements in the vector CX.
-
- CX (input) COMPLEX array, dimension (N)
- The vector whose elements will be summed.
-
- INCX (input) INTEGER
- The spacing between successive values of CX. INCX > 0.
