Parallel linear algebra library for the Denelcor HEP
Technical Report
·
OSTI ID:6255455
This paper discusses the implementation of a library of algorithms for problems in linear algebra on the Denelcor HEP. The package includes some of the most heavily used subroutines from LINPACK, that is, solution of linear systems based on LU, Cholesky, and QR factorizations as well as the appropriate triangular solvers. The concept followed is to code these routines in terms of high-level modules, which provides a vehicle to achieve both transportability and efficiency across a wide range of architectures. We discuss this concept in the context of a numerical linear algebra software library which is adaptable to highly parallel computing systems. However, the concept is expected to applicable to other libraries as well.
