<P>
Extensions to the library are
under way and will remove the
majority of the alignment
restrictions in the PBLAS.
The ScaLAPACK library and the
PBLAS are also being modified
to allow the possibility of a
partial first block, as well
as the incorporation of aggregate
(algorithmic) blocking. The
partial first block extension
makes ScaLAPACK fully compatible
with HPF and necessitates the
establishment of a new matrix
descriptor.
<P>
The incorporation of aggregate
(algorithmic) blocking at the
top-level ScaLAPACK routines,
as well as in the PBLAS, removes
the restriction of a user's
performance being tied to his
physical matrix distribution.
Instead, the algorithms will
perform at an optimal block size
predetermined inside the PBLAS.
