Overview
Parallel Engineering and Scientific Subroutine Library (Parallel ESSL) is a scalable mathematical subroutine library that supports parallel processing applications. Parallel ESSL for AIX® 5L V3.2 adds support for clusters of IBM POWER5(TM) servers connected with an IBM pSeries® High Performance Switch (HPS), and BladeCenter(TM) JS20 processors and POWER5 servers connected with a Myrinet-2000 Switch with Myrinet/PCI-X adapters running the AIX 5L V5.2 64-bit kernel.
The AIX 5L V5.3 (32-bit and 64-bit kernels) and V5.2 (32-bit kernel) are only supported on stand-alone clusters or clusters connected via a LAN supporting Internet Protocol (IP).
For communication, Parallel ESSL includes Basic Linear Algebra Communications Subprograms (BLACS), which use the Message Passing Interface (MPI). For computations, Parallel ESSL uses ESSL for AIX 5L subroutines.
The Parallel ESSL SMP Libraries are provided for use with the Parallel Environment MPI threads library. You can run single or multithreaded user space (US) or IP applications on all types of nodes. However, you cannot simultaneously call Parallel ESSL from multiple threads.
The Parallel ESSL GM libraries are provided for use with the MPICH-GM library and the Myrinet-2000 Switch with Myrinet/PCI-X adapters. IP is not supported.
The Parallel ESSL for AIX 5L libraries support both 32-bit and 64-bit environment applications. The subroutines can be called from applications written in Fortran, C, and C++.
Parallel ESSL for AIX 5L:
Runs under the AIX 5L V5.2 and V5.3 operating systems
Provides support for the new Fortran and C compilers
Supports the C interface for the BLACS
This is the last release of Parallel ESSL for AIX 5L that will support Parallel Systems Support Programs (PSSP) and the SP(TM) Switch2.
Parallel ESSL V3.2 does not support the SP Switch.
