Overview of the Level 2 PBLAS Subroutines

The Level 2 PBLAS include a subset of the standard set of distributed memory parallel versions of the Level 2 BLAS.

Note:: These subroutines are designed in accordance with the proposed Level 2 PBLAS standard. (See references [14], [15], and [17].) If these subroutines do not comply with the standard as approved, IBM will consider updating them to do so. If IBM updates these subroutines, the update could require modifications of the calling application program.
