Parallel PCG Solver for Nonconforming FE Problems: Overlapping of Communication and Computations
The paper deals with a parallel preconditioner for the solution of large nonconforming FE linear systems. The studied algorithm is based on the modified incomplete Cholesky factorization applied to a locally constructed app...

Semi-sparse Cholesky Factorization
The Cholesky factorization (shortly CHF) is one of basic methods to solve systems of linear equations (shortly SLEs). A task of the CHF is to compute the matrix. The process of Cholesky factorization of the origina...

Incremental Block Cholesky Factorization for Nonlinear Least Squares in Robotics
The paper presents an extension to the matrix factorization methods, a resumed factorization. It is suitable for incremental applications where the size of the system grows with time, but the rest remains without change. The impleme...

On Positive Semidefinite Modification Schemes for Incomplete Cholesky Factorization
Incomplete Cholesky factorizations have long been important as preconditioners for use in solving large-scale symmetric positive-definite linear systems. In this paper, we focus on the relationship between two important positive sem...

On Signed Incomplete Cholesky Factorization Preconditioners for Saddle-Point Systems
Limited-memory incomplete Cholesky factorizations can provide robust preconditioners for sparse symmetric positive-definite linear systems. In this paper, the focus is on extending the approach to sparse symmetric indefinite systems...

Analytical Model for Analysis of Cache Behavior during Cholesky Factorization and Its Variants
In this paper, we apply several transformations to Cholesky factorization and describe a new transformation called {em dynamic loop reversal} which can increase temporal and spatial locality. We also describe a probabilistic analyti...
