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

Changes for ESSL Version 3 Release 1.1

• The ESSL POWER Library, the ESSL Thread-Safe Library, and the ESSL SMP Library are tuned for the RS/6000 POWER3.
• The ESSL POWER Library, the ESSL Thread-Safe Library, and the ESSL SMP Library now support both 32-bit environment and 64-bit environment applications. For details on creating 64-bit environment applications see Chapter 4, Coding Your Program and Chapter 5, Processing Your Program. If you are migrating to a 64-bit environment, you may need to make changes to your calls to ERRSET. For details see ERRSET--ESSL ERRSET Subroutine for ESSL.
• ESSL for AIX provides distinct libraries for AIX 4.2.1 and AIX 4.3.2:
  • The AIX 4.2.1 ESSL Thread-Safe Library, the ESSL Thread-Safe POWER2 Library, and the ESSL SMP Library were built using the pthreads draft 7 library supplied on AIX 4.2.1. This is the same as ESSL Version 3.1.
  • The AIX 4.3.2 ESSL Thread-Safe Library, the ESSL Thread-Safe POWER2 Library, and the ESSL SMP Library were built using the pthreads library that conforms to the IEEE POSIX 1003.1-1996 specification supplied on AIX 4.3.
