Building Blocks

• Basic Linear Algebra Communication Subprograms (BLACS) for communicating parts of a matrix. May be optimized for hardware.
• Parallel BLAS (PBLAS). Level 1, 2 and 3 BLAS routines for distributed matrices and vectors.
• Sequential BLAS. May be optimized for hardware.
• Matrix transpose routines.
• Data distribution transformation routines for dynamically changing data distribution.
