Subject: PARALUTION, New Release 1.0

PARALUTION is a library for sparse iterative methods which can be
performed on various parallel devices, including multi-core CPU, GPU
(CUDA and OpenCL) and Intel Xeon Phi.

The 1.0 version of the PARALUTION Library supports multi-node and
multi-GPU configuration via MPI. All iterative solvers support global
operations (i.e. distributed matrices and vectors) and all
preconditioners can be used in a block-Jacobi fashion locally on each
node/GPU. In addition, the software provides a global (fully
distributed) Pair-Wise AMG solver.

The global AMG solver builds all the levels (and the corresponding
operators) in parallel (i.e. by utilizing all MPI ranks). All AMG
solvers have optimized support for non-linear/time stepping schemes.
Typically, in such configuration the matrix values are changed while
the sparsity pattern of the matrix remains the same. In this case,
after the first call, the our AMG solvers need significantly less time
to re-build. Also, in the new version all multi-grid solvers support
V, W and K-cycles.

With the new release, we also provide multi-node benchmarks available

The library comes with a dual license model, where the user can choose
between three versions.

Subject: Uncertainty Quantification, USA, Jun 2015

The Institute for Mathematics and its Applications is hosting the New
Directions Short Course: Introduction to Uncertainty Quantification
from June 15-26, 2015.

Uncertainty quantification (UQ) lies at the confluence of many fields,
including probability, statistics, data analysis, computational
mathematics, and mathematical modeling. It touches upon almost any
field that involves models, whether of natural or engineered systems,
and data.

Organized by Luis Tenorio (Colorado School of Mines) and Youssef
Marzouk (Massachusetts Institute of Technology), the objective of the
course is to help participants from different backgrounds obtain the
basic understanding and tools needed to use UQ in their fields of
interest. In addition, the course will present snapshots of current
research and examples of UQ in different application areas, so that
the participants are aware of the types of methods that are in current

This course will be of interest to people involved in science and
engineering applications and information-based decision making, and it
will also be of interest to people who want to understand the
fundamental mathematical ideas and tools underlying this endeavor.
