Subject: Software Release: ROSTAPACK: RObust STAbility PACKage 1.0


I am pleased to announce the 1.0 release of ROSTAPACK: RObust
STAbility PACKage. ROSTAPACK is a new AGPL-licensed library for
computation and fast approximation of robust stability measures for
linear dynamical systems. This initial 1.0 release contains scalable
methods intended for large-scale problems for approximating the
complex or real stability radius, the H-infinity norm, and the
spectral value set abscissa or radius (including the pseudospectral
abscissa and radius). A future update will add state-of-the-art exact
methods, intended for smaller-scale problems, for computing (not
approximating) these measures.

Subject: Inter-Facial Dynamics and FSI Problems, China, Jun 2018


We are organizing a workshop on inter-facial dynamics and
fluid-structure interaction problems. The focus will be on different
aspects of interface problems, free boundary and moving interface
problems, and fluid- structure interactions including modeling and
analysis, the related theory and analysis of partial differential
equations (PDEs), various numerical methods, and applications. The
interactions include fluid and fluid, fluid and solid, fluid and
elasticity materials interactions. An important goal of this workshop
is to foster collaboration between computational mathematicians and
engineers.

Subject: Microlocal Analysis Meets Data Science, UK, Jun 2018


We would like to bring to your attention the following workshop

"Microlocal analysis meets data science to solve large scale real life
inverse problems", 18-20 June 2018, Alan Turing Institute, London

A key consideration in inverse problems in imaging is whether sharp
edges and other features of the image are faithfully recovered in the
reconstruction process. To analyse this we must understand how such
features appear in the data. Microlocal analysis provides a
theoretical framework for studying this propagation of sharp, or high
frequency, features in the image to the corresponding features in the
data, and then the inversion of this process which occurs in the
reconstruction. In particular, microlocal analysis can tell us in many
cases what features of an object to be imaged are "visible" from a
given data set, and whether more data will be required for faithful
reconstruction.

Subject: PUMPS+AI Summer School, Spain, Jul 2018


On its ninth edition, the Programming and tUning Massively Parallel
Systems summer school (PUMPS) premiers a brand-new "+AI" design,
offering researchers and graduate students a unique opportunity to
improve their skills with cutting-edge techniques and hands-on
experience in developing and tuning applications for many-core
processors with massively parallel computing resources like GPU
accelerators, with more content devoted to artificial intelligence.

The summer school is oriented towards advanced programming and
optimizations, and thus previous experience in basic GPU programming
will be considered in the selection process. We will also consider the
current parallel applications, numerical methods, and AI techniques
you are familiar with, and the specific optimizations you would like
to discuss. Some of the topics that will be covered during the course
are: AI / DEEP Learning; High-level programming models on GPUs: OmpSs,
OpenACC; CUDA Algorithmic Optimization Strategies; Dealing with Sparse
and Dynamic data; Efficiency in Large Data Traversal; Reducing Output
Interference; Controlling Load Imbalance and Divergence; Acceleration
of Collective Operations; Dynamic Parallelism and HyperQ; Debugging
and Profiling CUDA Code; Multi-GPU and multi-node Execution;
Architecture Trends and Implications.

Participants will have access to a multi-node cluster of GPUs, and
will learn to program and optimize applications in languages such as
CUDA and OmpSs. Teaching Assistants will be available to help with
your hands-on lab assignments. At poster and code clinic sessions you
may show your current work and applications you are optimizing. NVIDIA
will award the best poster presentation and course achievements.

Applications due: May 31, 2018
Summer school: July 16-20, 2018

Location: Barcelona Supercomputing Center / Computer Architecture
