How can we provide
<B>portable</B><A NAME="3588"> </A>
software for dense
linear algebra
computations that
is <B>efficient</B>
on a wide range of
modern distributed-memory
computers?
Answering this question --
and providing the
appropriate software --
has been an objective
of the ScaLAPACK
project.
<P>
The ScaLAPACK
software has been
designed specifically
to achieve high
efficiency for a
wide range of modern
distributed-memory
computers.
Examples of such
computers include
the Cray T3D and
T3E computers,
the IBM Scalable
POWERparallel SP
series, the Intel
iPSC and Paragon
computers, the
nCube-2/3 computer,
networks and clusters
of workstations (NoWs<A NAME="3590"> </A>
and CoWs<A NAME="3591"> </A>), and ``piles''
of PCs (PoPCs)<A NAME="3592"> </A>.
