Subject: Tensorlab 3.0 Release

It is our pleasure to announce the release of Tensorlab 3.0.
Tensorlab is a Matlab toolbox for tensor computations, structured data
fusion and complex optimization.

In Tensorlab 3.0, dedicated algorithms for the decomposition in
multilinear rank-(Lr,Lr,1) terms have been added. The new release
introduces a tensorization framework and offers increased support for
handling large-scale and structured datasets. The performance,
user-friendliness and capabilities of the domain specific language for
structured data fusion have been enhanced, and a new tool has been
developed for the visualization of tensors of arbitrary order.

An extensive new online manual has been developed. A collection of
demos illustrates how Tensorlab can be used in various
applications. Code, manual, demos and detailed release notes are
available from the renewed website http://www.tensorlab.net/.

The toolbox is free to use for non-commercial research. We hope that
you will find it useful in your research. We welcome all suggestions
and feedback.

Subject: European Trilinos User Group Meeting, Germany, Apr 2016

The 5th European Trilinos User Group Meeting (EuroTUG2016) will take
place April 18-20 2016 in Garching near Munich at the Leibniz
Rechenzentrum (LRZ), jointly hosted this year by LRZ and TU Munich.

EuroTUG is an annual meeting that brings together researchers,
developers and users of the open source scientific software collection
'Trilinos' (http://www.trilinos.org) from Sandia National
Laboratories, USA. The meeting is a platform for discussions and
information on latest trends in HPC scientific software, massively
parallel computing, efficient algorithms and HPC enabling
technologies, with an emphasis on Trilinos usage.

EuroTUG will supply an overview of the Trilinos software suit as well
as beginners and advanced tutorials. One of this year-s focuses is on
usage of Trilinos-Kokkos, a programming model for performance portable
applications targeting all major platforms including Nvidia, Xeon Phi
and manycore complex hardware node architectures. Details can be
found at: http://www.mhpc.mw.tum.de/index.php?id=38

Subject: Postdoc/Researcher Position, Dynamism-aware HPC, NTNU, Norway

A postdoc/researcher position is available within the "Run-time
Exploitation of Application Dynamism for Energy-efficient eXascale
computing (READEX)" Horizon 2020 EU project at NTNU, Trondheim, Norway
with application deadline April 24 2016.

The objective of the READEX project is to develop a design methodology
and tool-suite that enables exploiting dynamic application behaviour
in HPC systems for improved energy efficiency. The project will build
on, combine and extend research results from system scenario based
design in the embedded domain and HPC auto-tuning technology.

The postdoctoral fellow/researcher will mainly contribute to the following
tasks in collaboration with other researchers at NTNU:
(a) Identify dynamic behaviour in HPC applications
(b) Determine the performance and energy impact of changing platform
    settings (e.g. voltages, clock frequencies, communication
    algorithms, etc.) for each application phase
(c) Develop design time techniques that detect dynamic behaviour and
    determine near-optimal platform settings for each application
    phase
(d) Develop low-overhead runtime techniques that select platform
    settings for each phase based on information from the design time
    analysis and additional dynamic measurements.

PhD/Doctorate Positions in High Performance Computing:
An Exascale Hyperbolic PDE Engine - www.exahype.eu
at Technical University of Munich and at Durham University

ExaHyPE is a Horizon 2020 project (2015-2019) to develop a novel
simulation engine for hyperbolic PDE problems at exascale. We
especially tackle grand-challenge simulations in Seismology and
Astrophysics. The underlying simulation engine will be based on
high-order discontinuous Galerkin discretization on dynamically
adaptive Cartesian grids. To strengthen our team, we're looking for a
doctoral researcher who ideally should already have a strong
background on HPC topics such as (but not restricted to) MPI
programming, load balancing or performance optimization for multi- and
manycore CPUs. Interest in the application areas is
advantageous. However, we see the ability and passion to integrate and
learn new techniques as your most important qualification.

See

for full details.

Applications will be considered until the positions are filled. To
ensure a timely start at Oct 1, 2016, we appreciate applications
before May 15. Please send your application as a single PDF document
