Parallel Engineering and Scientific Subroutine Library for AIX Version 2 Release 3: Guide and Reference

|Changes for Parallel ESSL Version 2 Release 2

• The Parallel ESSL Libraries are tuned for the |POWER3-II thin, wide, and high nodes and the SP Switch2.
• The Dense Linear Algebraic Equations Subroutines now include these new subroutines:
  • Inverse of a real or complex general matrix
  • Reciprocal of the condition number of a real or complex general matrix
  • General Matrix QR factorization
  • Least Squares solutions to linear systems of equations for real general matrices
• The Eigensystems Analysis Subroutines now include these new subroutines:
  • Selected Eigenvalues and optionally the eigenvectors of a complex Hermitian matrix
  • Selected Eigenvalues and optionally the eigenvectors of a real symmetric positive definite generalized eigenproblem
  • Reduce a complex Hermitian matrix to tridiagonal form
  • Reduce a real symmetric positive definite generalized eigenproblem to standard form
• The Utilities Subroutines now include these new subroutines:
  • Compute the norm of a real or complex general matrix
• The Parallel ESSL POWER2 and Thread-Tolerant POWER2 libraries are no longer provided; the Parallel ESSL Serial and the Parallel ESSL SMP library should be used instead. See Migrating to Parallel ESSL Version 2 Release 2 for additional information.
• Support is withdrawn for calling Parallel ESSL from HPF; as a result the Parallel ESSL HPF libraries, HPF module, HPF IVP, and sample HPF programs are no longer provided.
• The Parallel ESSL Version 2 Guide and Reference manual is provided as a Portable Document Format (PDF) file with the product package; the postscript file is no longer provided
• The Parallel ESSL Product Package is now distributed on a CD.
