The ESSL SMP Library provides thread-safe versions of the ESSL
subroutines for use on RS/6000 SMP (for example 604e) processors. In
addition, a subset of these subroutines are also multithreaded versions;
that is, they support the shared memory parallel processing programming
model. You do not have to change your existing application programs
that call ESSL to take advantage of the increased performance of using the SMP
processors. You can simply re-link your existing programs. For a
list of the multithreaded subroutines in the ESSL SMP Library, see Table 21.
The ESSL Thread-Safe Library provides thread-safe versions of
the ESSL subroutines for use on all RS/6000 processors. You may use
this library to develop your own multithreaded applications.
If your existing application program calls ESSL, you only need to re-link
your program to take advantage of the increased performance of the ESSL SMP
Library or to use the ESSL Thread-Safe Library.
ESSL provides new subroutines (_GETRF and _GETRS), bringing the total
number of subroutines to 458.
For those ESSL subroutines that require extra working storage to perform
computations, ESSL now provides a way to dynamically allocate storage when it
does not need to persist after the subroutine call. See Using Auxiliary Storage in ESSL.
