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

Changes for Parallel ESSL Version 2 Release 1.2

• The Parallel ESSL POWER Libraries and the Parallel ESSL SMP Libraries are tuned for the |POWER3 SMP thin, wide, and high nodes.
• New Level 2 and Level 3 PBLAS long-precision complex message-passing subroutines are provided.
• New Dense Linear Algebraic Equation long-precision real and complex combined factorization and solve message-passing subroutines are provided.
• Updated Banded Linear Algebraic Equation Subroutines, PDDTTRS and DTTRS, support Diagonally-Dominant General Tridiagonal Matrix Transpose Solve
• Banded Linear Algebraic Equation Subroutines, PDPBSV, PDGTSV, PDDTSV and PDPTSV have been modified for the case where N is greater than zero and NRHS is zero so that the matrix is factored. Previously, this was a quick return condition and the matrix was not factored.
