The Parallel Solution of Triangular Systems of Linear Equations
We present a parallel algorithm for solving triangular systems of linear equations on distributed-memory multiprocessor machines. The parallelism is achieved by partitioning the rows of the coefficient matrix in segments of a fixed size and distributing these sets in a wrap-around fashion among the processors, connected in a ring. The granularity of the algorithm is controlled by varying the se...
متن کاملStructure-adaptive parallel solution of sparse triangular linear systems
Solving sparse triangular systems of linear equations is a performance bottleneck in many methods for solving more general sparse systems. Both for direct methods and for many iterative preconditioners, it is used to solve the system or improve an approximate solution, often across many iterations. Solving triangular systems is notoriously resistant to parallelism, however, and existing paralle...
متن کاملOn Parallel Solution of Sparse Triangular Linear Systems in CUDA
The acceleration of sparse matrix computations on modern many-core processors, such as the graphics processing units (GPUs), has been recognized and studied over a decade. Significant performance enhancements have been achieved for many sparse matrix computational kernels such as sparse matrix-vector products and sparse matrix-matrix products. Solving linear systems with sparse triangular struc...
متن کاملParallel complexity of linear system solution
Spend your few moment to read a book even only few pages. Reading book is not obligation and force for everybody. When you don't want to read, you can get punishment from the publisher. Read a book becomes a choice of your different characteristics. Many people with reading habit will always be enjoyable to read, or on the contrary. For some reasons, this parallel complexity of linear system so...
