Developing software for current and especially for future
architectures will require knowledge about parallel programming
techniques of applications and library p- grammers. Multi-core
processors are already available today, and processors with a dozen
and more cores are on the horizon. The major driving force in
hardware development, the game industry, has - ready shown interest
in using parallel programming paradigms, such as OpenMP for further
developments. Therefore developers have to be supported in the even
more complex task of programming for these new architectures. HLRS
has a long-lasting tradition of providing its user community with
the most up-to-date software tools. Additionally, important
research and development projects are worked on at the center:
among the software packages developed are the MPI correctness
checker Marmot, the OpenMP validation suite and the M-
implementations PACX-MPI and Open MPI. All of these software
packages are - ing extended in the context of German and European
community research projects, such as ParMA, the InterActive
European Grid (I2G) project and the German C- laborative Research
Center (Sonderforschungsbereich 716). Furthermore, ind- trial
collaborations, i.e. with Intel and Microsoft allow HLRS to get its
software production-grade ready. In April 2007, a European project
on Parallel Programming for Multi-core - chitectures, in short
ParMA was launched, with a major focus on providing and developing
tools for parallel programming.
This state-of-the-art survey features topics related to the impact
of multicore, manycore, and coprocessor technologies in science and
large-scale applications in an interdisciplinary environment. The
papers included in this survey cover research in mathematical
modeling, design of parallel algorithms, aspects of microprocessor
architecture, parallel programming languages, hardware-aware
computing, heterogeneous platforms, manycore technologies,
performance tuning, and requirements for large-scale applications.
The contributions presented in this volume are an outcome of an
inspiring conference conceived and organized by the editors at the
University of Applied Sciences (HfT) in Stuttgart, Germany, in
September 2012. The 10 revised full papers selected from 21
submissions are presented together with the twelve poster abstracts
and focus on combination of new aspects of microprocessor
technologies, parallel applications, numerical simulation, and
software development; thus they clearly show the potential of
emerging technologies in the area of multicore and manycore
processors that are paving the way towards personal supercomputing
and very likely towards exascale computing.

The contributions presented in this volume offer a survey on the
state of the art, the concepts and perspectives for future
developments. They are an outcome of an inspiring conference
conceived and organized by the editors at the Karlsruhe Institute
Technology (KIT) in September 2011. The twelve revised full papers
presented together with two contributed papers focus on combination
of new aspects of microprocessor technologies, parallel
applications, numerical simulation, and software development; thus
they clearly show the potential of emerging technologies in the
area of multicore and manycore processors that are paving the way
towards personal supercomputing and very likely towards exascale
computing.
Insects as a group occupy a middle ground in the biosphere between
bacteria and viruses at one extreme, amphibians and mammals at the
other. The size and general nature of insects present special
problems to the study of ento mology. For example, many
commercially available instruments are geared to measure in grams,
while the forces commonly encountered in studying insects are in
the milligram range. Therefore, techniques developed in the study
of insects or in those fields concerned with the control of insect
pests are often unique. Methods for measuring things are common to
all sciences. Advances some times depend more on how something was
done than on what was measured; indeed a given field often
progresses from one technique to another as new methods are
discovered, developed, and modified. Just as often, some of these
techniques find their way into the classroom when the problems
involved have been sufficiently ironed out to permit students to
master the manipulations in a few laboratory periods. Many
specialized techniques are confined to one specific research labora
tory. Although methods may be considered commonplace where they are
used, in another context even the simplest procedures may save
considerable time. It is the purpose of this series (1) to report
new developments in method ology, (2) to reveal sources of groups
who have dealt with and solved particular entomological problems,
and (3) to describe experiments which may be appli cable for use in
biology laboratory courses."
