Changes for Parallel ESSL Release 2.0 for AIX

• Parallel ESSL Release 2.0 provides a new set of subroutines that are callable from application programs written in High Performance Fortran (HPF). The HPF subroutines covers the same range of mathematical function that the message passing subroutines cover.

• The Dense Linear Algebraic Equations subroutines now include solutions to linear systems of equations for complex general and complex Hermitian matrices.

• The Banded Linear Algebraic Equations subroutines now include solutions to linear systems of equations for real positive definite symmetric band matrices, real general tridiagonal matrices, and diagonally-dominant real general tridiagonal matrices.

• New short-precision versions for the Fourier transforms subroutines are provided in the product package.

• Parallel ESSL Release 2.0 supports clusters of IBM RS/6000* workstations.
