A Parallel Multi-threaded Solver for Symmetric Positive Definite Bordered-Band Linear Systems
Springer (2016-04)We present a multi-threaded solver for symmetric positive definite linear systems where the coefficient matrix of the problem features a bordered-band non-zero pattern. The algorithms that implement this approach heavily ... -
A Proposal to Extend the OpenMP Tasking Model for Heterogeneous Architectures
Springer Berlin Heidelberg (2009)OpenMP has evolved recently towards expressing unstructured parallelism, targeting the parallelization of a broader range of applications in the current multicore era. Homogeneous multicore architectures from major vendors ...

Accelerating BST Methods for Model Reduction with Graphics Processors
Springer Berlin Heidelberg (2012)Model order reduction of dynamical linear time-invariant system appears in many scientific and engineering applications. Numerically reliable SVD-based methods for this task require O(n3) floating-point arithmetic operations, ... -
Accelerating Model Reduction of Large Linear Systems with Graphics Processors
Springer Berlin Heidelberg (2012)Model order reduction of a dynamical linear time-invariant system appears in many applications from science and engineering. Numerically reliable SVD-based methods for this task require in general O(n3) floating-point ...

An Extension of the StarSs Programming Model for Platforms with Multiple GPUs
Springer Berlin Heidelberg (2009)While general-purpose homogeneous multi-core architectures are becoming ubiquitous, there are clear indications that, for a number of important applications, a better performance/power ratio can be attained using specialized ...

Leveraging Task-Parallelism in Energy-Efficient ILU Preconditioners
Springer Berlin Heidelberg (2012)We analyze the energy-performance balance of a task-parallel computation of an ILU-based preconditioner for the solution of sparse linear systems on multi-core processors. In particular, we elaborate a theoretical model ...

Parallelization of Multilevel ILU Preconditioners on Distributed-Memory Multiprocessors
Springer Berlin Heidelberg (2012)In this paper we investigate the parallelization of the ILUPACK library for the solution of sparse linear systems on distributed-memory multiprocessors. The parallelization approach employs multilevel graph partitioning ...

Revisiting the Gauss-Huard Algorithm for the Solution of Linear Systems on Graphics Accelerators
Springer (2016-04-02)In 1979, P. Huard presented an efficient variant of the Gauss-Jordan elimination for the solution of linear systems. In particular, this alternative algorithm exhibits the same computational cost as the traditional LU-based ...
