Abstract

Domi (Greek for "structure") is a Trilinos package that provides support for multi-dimensional data arrays distributed over multiple processors of a high performance computing system. The software supports data arrays of arbitrary number of dimensions mapped to a multi-dimensional grid of processors. Domi provides local access to the data, as well as the ability to compute global quantities such as norms, maxima and minima. Data arrays can be constructed with boundary and communication padding, necessary for finite difference algorithms, and provides high-level methods for communicating data between processors to update these buffers. The distributed maps and vectors in Domi can be converted to the equivalent data structures in Epetra and Tpetra (both of which assume unstructured data), using view semantics when appropriate, for use with other Trilinos solvers.

Tifpack v 1.0

Software Heroux, Michael

A package for computing and applying algebraic preconditioners in the context of preconditioned iterative methods. It is related to the existing Ifpack package in Trilinos but provides support for template scalar and ordinal types and explicitly relies on Tpetra and Kokkos instead of Epetra. Algebraic preconditioners are used by iterative solvers as solution method in engineering and scientific applications, including nonlinear equation solving, time integration, sensitivity analysis, stability analysis, optimization, and uncertainty quantification.

Tpetra Kernel Package

Software Heroux, Michael

A package of classes for constructing and using distributed sparse and dense matrices, vectors and graphs. Templated on the scalar and ordinal types so that any valid floating-point type, as well as any valid integer type can be used with these classes. Other non-standard types, such as 3-by-3 matrices for the scalar type and mod-based integers for ordinal types, can also be used. Tpetra is intended to provide the foundation for basic matrix and vector operations for the next generation of Trilinos preconditioners and solvers, It can be considered as the follow-on to Epetra. Tpetra provides distributed memory operations viamore »« less
Continuation and bifurcation analysis of large-scale dynamical systems with LOCA.

Conference Salinger, Andrew; Phipps, Eric; Pawlowski, Roger

Dynamical systems theory provides a powerful framework for understanding the behavior of complex evolving systems. However applying these ideas to large-scale dynamical systems such as discretizations of multi-dimensional PDEs is challenging. Such systems can easily give rise to problems with billions of dynamical variables, requiring specialized numerical algorithms implemented on high performance computing architectures with thousands of processors. This talk will describe LOCA, the Library of Continuation Algorithms, a suite of scalable continuation and bifurcation tools optimized for these types of systems that is part of the Trilinos software collection. In particular, we will describe continuation and bifurcation analysis techniquesmore »« less
Aleph

Software

Aleph is a PIC/DSMC (particle-in-cell/direct simulation Monte Carlo) software package for the simulation of low temperature plasmas. Aleph is intended to be a production quality code capable of handling complex 3D geometries. Unstructured triangular (2D) or tetrahedral (3D) meshes are used to represent simulation domains. Aleph runs either in serial on a single processor or desktop machine, or can be run in parallel using the MPI message-passing library, to enable faster performance on large problems. Aleph employs dynamic load balancing to efficiently harness thousands of processors on high performance computers and enable simulations of up to millions of mesh elementsmore »« less
Xpetra Package

Software

Xpetra provides a single interface that allows the use of either Epetra or Tpetra linear algebra libraries from the same source code. Library developers need only learn and use the syntax of Xpetra; the resulting libraries can use either Epetra or Tpetra.
