ScaLAPACK is portable across a wide range of distributed-memory environments such as the IBM SP series, Intel series (Gamma, Delta, Paragon), Cray T3 series, TM CM-5, clusters of workstations, and any system for which PVM  or MPI  is available. Similar to the BLAS and LAPACK, many of the goals of the ScaLAPACK project, particularly portability, are aided by developing and promoting standards, especially for low-level communication and computation routines. We have been successful in attaining these goals, limiting most machine dependencies to two standard libraries called the BLAS, or Basic Linear Algebra Subroutines, and BLACS, or Basic Linear Algebra Communication Subroutines. ScaLAPACK will run on any machine where both the BLAS and the BLACS are available.
