Documentation: Changes: 2.1.5

General:

• Replace autoconf-configure with python-configure. Tested on Linux, IRIX, Alpha-OSF, Mac OSX
• Added PETSc interface to UMFPACK (Seq)
• SuperLU & SuperLU_DIST insterface is updated to the latest download versions. Complex version of these packages are now supported.
• Added Support for QR factorization into PETSc/SPOOLES interface (Seq)
• Added Support for installing PETSc with TAU instrumentation package. Please check config files in bmake/linux_tau.
• Added support for Cray SX-6 vector machine

Vec:

• Added VecMaxPointwiseDivide()

Mat:

• Added MatTranspose() for SBAIJ
• Added MatConvert_SeqAIJ_SeqSBAIJ()
• Added MatGetInertia()
• Added MatAXPY() to SBAIJ and BAIJ mat formats
• Added MatSetValuesBlocked() for SEQSBAIJ and MPISBAIJ formats
• Improved single precision SSE factorization routines
• Added scalable parallel binary viewer for MPIAIJ matrix

SLES:

• PCSetUp() now defaults to ICC for SBAIJ
• BoomerAMG preconditioner now defaults to zero initial guess
• Added GetTotalBlocks() and GetLocalBlocks() to PCBJacobi
• Improved LU and ILU damping for AIJ matrix type - New factorization damping policy (check manual)

SNES:

TS:

• Added TSGetDuration()

Other:

• Turned off logging of objects and actions by default - saves memory usage
• Reduce memory usage for DA and SDA objects
• Support generation of SBAIJ matrices from DA

Fortran:

• Added f90 support for intel compilers on linux and linux64
