The format of the output from PDDTTRF and DTTRF has changed. Therefore, the factorization and solve must be performed using Parallel ESSL Version 2 Release 1.2.
Banded Linear Algebraic Equations 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. For all other subroutines, no changes to your application programs are required if you are migrating from Parallel ESSL Version 2 Release 1.1 to Parallel ESSL Version 2 Release 1.2.
