Engineering and Scientific Subroutine Library for AIX Version 3 Release 3: Guide and Reference

Changes for ESSL Version 3 Release 1.2

• The ESSL POWER Library, the ESSL Thread-Safe Library, and the ESSL Symmetric Multi-Processing (SMP) Library are tuned for the |POWER3 SMP thin, wide, and high nodes.
• The serial and SMP performance of the packed Dense Linear Algebraic Equation subroutines, _PPF, _PPFCD, and _PPICD have been improved in many cases by utilizing new algorithms based on recursive packed storage format (see references [52], [66], and [67]).
• The SMP performance of the Dense Linear Algebraic Equation subroutine, DPOF, has been improved for a positive definite symmetric matrix stored in upper storage mode.
• Additional multithreaded ESSL SMP subroutines are provided (see Table 21).
