As the name suggests, applications in computational fluid dynamics (CFD) were the primary focus of the effort. « lessĪ novel parallel processing supercomputer, called the Navier-Stokes Computer (NSG), has been designed and built for the solution of scientific problems. These operations can be optimized for each architecture, but the underlying numerical algorithms will be the same for all machines. We propose to restructure the algorithms in terms of calls to a small number of extended Basic Linear algebra Subroutines each of which implements a basic operation such as matrix multiplication, rank-k matrix updates, and the solution of triangular systems. LINPACK and EISPACK have provided an important infrastructure for scientific computing on serial machines, but they were not designed to exploit the profusion of parallel and vector architectures not becoming available. The library will be based on the well-known and widely used LINPACK and EISPACK more » packages for linear equation solving, eigenvalue problems, and linear least squares. This library, which will be freely accessible via computer network, not only will ease code development, make codes more portable among machines of different architectures, and increase efficiency, but also will provide tools for evaluating computer performance. The library is intended to provide a uniform set of subroutines to solve the most common linear algebra problems and to run efficiently on a wide range of architectures. We propose to design and implement a transportable linear algebra library in Fortran 77 for efficient use on high-performance computers.
