The goal of the LAPACK project is to design and implement a portable linear algebra library for efficient use on variety high-performance computers. based widely used LINPACK EISPACK packages solving equations, eigenvalue problems, least-squares but extends their functionality in number ways. major methodology making algorithms run faster restructure them perform block matrix operations (e.g., matrix-matrix multiplication) inner loops. These may be optimized exploit memory hierarchy specific...
This paper describes and compares three parallel algorithms for solving sparse triangular systems of equations. These methods involve some preprocessing overhead are primarily interest in many with the same coefficient matrix. The first approach is to use a fixed blocksize form inverse diagonal blocks. second variable reorder unknowns so that blocks matrices. We call latter technique level scheduling because how it represented adjacency graph, we consider both row-wise jagged storage...
The CRAY T3E is a scalable shared-memory multiprocessor based on the DEC Alpha 21164 microprocessor. system includes number of novel architectural features designed to tolerate latency, enhance scalability, and deliver high performance scientific engineering codes. Included among these are stream buffers, which detect prefetch down small-stride reference streams, E-registers, provide latency hiding non-unit-stride access capabilities, barrier fetch_and_op synchronization support, scalable,...
We present a scale-invariant theory, conformal gravity, which closely resembles the geometrodynamical formulation of general relativity (GR). While previous attempts to create theories gravity have been based on Weyl's idea compensating field, our direct approach dispenses with this and is built by extension method best matching w.r.t scaling developed in parallel particle dynamics paper one authors. In spatially-compact GR, there an infinity degrees freedom that describe shape 3-space...
The LAPACK project, an effort to produce a numerical linear algebra library that runs efficiently on shared-memory vector and parallel processors, is discussed. A description given of what was done achieve performance, results are for various computers. Future directions research computers also discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The square root of a sum squares is well known to be prone overflow and underflow. Ad hoc scaling intermediate results, as has been done in numerical software such the BLAS LAPACK, mostly avoids problem, but it can still occur at extreme values range representable numbers. More careful scaling, implemented recent versions standard algorithms, may come expense performance or clarity. This work reimplements vector 2-norm generation Givens rotations from Level 1 improve their design. In...
