Overview
IBM Parallel ESSL is a scalable mathematical subroutine library that supports parallel processing applications on clusters of IBM pSeries(TM) servers running Linux.
Parallel ESSL supports the Single Program Multiple Data (SPMD) programming model.
Parallel ESSL provides over 100 subroutines in six major areas of mathematical computations:
Level 2 parallel basic linear algebra subprograms (PBLAS)
Level 3 PBLAS
Linear algebraic equations
Eigensystem analysis and singular value analysis
Fourier transforms
Random number generation
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 Linux on pSeries subroutines.
The Parallel ESSL GM libraries are provided for use with the MPICH-GM library and the Myrinet-2000 switch with Myrinet/PCI-X adapters. Internet protocol (IP) is not supported.
The Parallel ESSL GM libraries support both 32-bit environment and 64-bit environment applications. The subroutines can be called from application programs written in Fortran, C, and C++.
Parallel ESSL runs under the SuSE Linux Enterprise Server 8 (SLES) for IBM iSeries(TM)/pSeries operating system.

Description
IBM Parallel Engineering and Scientific Subroutine Library for Linux on pSeries is functionally equivalent to the Parallel ESSL for AIX® 5L V2.3 (5765-C41) product, except that:
The switch supported is the Myrinet-2000 with Myrinet/PCI-X adapters.
IP is not supported.
Multiple Computational Threads are not supported.
The Parallel ESSL header file does not support the IBM Open Class® Complex Mathematics Library.
All Parallel ESSL libraries provide high levels of performance for numerically intensive computing jobs on the respective processors. All versions provide mathematically equivalent results.
Refer to the Parallel Engineering and Scientific Subroutine Library for AIX, V2.3 and Linux on pSeries, V3.1 Guide and Reference, V3.1 for details. Hardcopy documentation is not shipped with the product. Documentation can be viewed or printed as detailed in the Publications section.
The Parallel ESSL software license agreement is shipped, viewed, and accepted electronically.
