text: We model negative polarization, which is observed for planetary regoliths
at backscattering, solving a full wave problem of light scattering with a numerically
exact Discontinuous Galerkin Time Domain (DGTD) method. Pieces of layers with
the bulk packing density of particles close to 0.5 are used. The model particles
are highly absorbing and have irregular shapes and sizes larger than the wavelength
of light. This represents a realistic analog of low-albedo planetary regoliths.
Our simulations confirm coherent backscattering mechanism of the origin of negative
polarization. We show that angular profiles of polarization are stabilized if
the number of particles in a layer piece becomes larger than ten. This allows
application of our approach to the negative polarization modeling for planetary
regoliths.

text: 'We review our results of numerical simulations of light scattering from different
systems of densely packed irregular particles. We consider spherical clusters,
thick layers and monolayers with realistic topologies and dimensions much larger
than the wavelength of light. The maximum bulk packing density of clusters is
0.5. A numerically exact solution of the electromagnetic problem is obtained using
the Discontinuous Galerkin Time Domain method and with application of high- performance
computing. We show that high packing density causes light localization in such
structures which makes an impact on the opposition phenomena: backscattering intensity
surge and negative linear polarization feature. Diffuse multiple scattering is
significantly reduced in the case of non-absorbing particles and near-field interaction
results in a percolation-like light transport determined by the topology of the
medium. With this the negative polarization feature caused by single scattering
gets enhanced if compared to lower density samples. We also confirm coherent double
scattering mechanism of negative polarization for light scattered from dense absorbing
slabs. In this case convergent result for the scattering angle polarization dependency
at backscattering can be obtained for a layer of just a few tens of particles
if they are larger than the wavelength.'

text: We study a double-scattering coherent mechanism of negative polarization (NP)
near opposition that is observed for powder-like surfaces. The problem is solved
numerically for absorbing structures with irregular constituents, cubes, spheres,
and ellipsoids larger than the wavelength of incident light. Our simulations show
that double scattering between two random irregular particles shows weak NP. Adding
one more particle significantly increases the relative contribution of double
scattering which enhances NP. Simulations with regular shapes and controlled geometric
parameters show that the interference mechanism is sensitive to the geometry of
the scattering system and can also result in no polarization or even strong enhancement
of positive polarization at backscattering.

text: Solving partial differential equations on unstructured grids is a cornerstone
of engineering and scientific computing. Nowadays, heterogeneous parallel platforms
with CPUs, GPUs, and FPGAs enable energy-efficient and computationally demanding
simulations. We developed the HighPerMeshes C++-embedded Domain-Specific Language
(DSL) for bridging the abstraction gap between the mathematical and algorithmic
formulation of mesh-based algorithms for PDE problems on the one hand and an increasing
number of heterogeneous platforms with their different parallel programming and
runtime models on the other hand. Thus, the HighPerMeshes DSL aims at higher productivity
in the code development process for multiple target platforms. We introduce the
concepts as well as the basic structure of the HighPerMeshes DSL, and demonstrate
its usage with three examples, a Poisson and monodomain problem, respectively,
solved by the continuous finite element method, and the discontinuous Galerkin
method for Maxwell’s equation. The mapping of the abstract algorithmic description
onto parallel hardware, including distributed memory compute clusters, is presented.
Finally, the achievable performance and scalability are demonstrated for a typical
example problem on a multi-core CPU cluster.

text: 'In scientific computing, unstructured meshes are a crucial foundation for
the simulation of real-world physical phenomena. Compared to regular grids, they
allow resembling the computational domain with a much higher accuracy, which in
turn leads to more efficient computations.
There exists a wealth of supporting
libraries and frameworks that aid programmers with the implementation of applications
working on such grids, each built on top of existing parallelization technologies.
However, many approaches require the programmer to introduce a different programming
paradigm into their application or provide different variants of the code. SYCL
is a new programming standard providing a remedy to this dilemma by building on
standard C ++17 with its so-called single-source approach: Programmers write standard
C ++ code and expose parallelism using C++17 keywords. The application is
then
transformed into a concrete implementation by the SYCL implementation. By encapsulating
the OpenCL ecosystem, different SYCL implementations enable not only the programming
of CPUs but also of heterogeneous platforms such as GPUs or other devices. For
the first time, this paper showcases a SYCL-
based solver for the nodal Discontinuous
Galerkin method for Maxwell’s equations on unstructured meshes. We compare our
solution to a previous C-based implementation with respect to programmability
and performance on heterogeneous platforms.Proceedings of the 29th Annual IEEE International
Conference on Application-Specific Systems, Architectures and Processors (ASAP).

text: Semi-guided waves confined in dielectric slab waveguides are being considered
for oblique angles of propagation. If the waves encounter a linear discontinuity
of (mostly) arbitrary shape and extension, a variant of Snell's law applies, separately
for each pair of incoming and outgoing modes. Depending on the effective indices
involved, and on the angle of incidence, power transfer to specific outgoing waves
can be allowed or forbidden. In particular, critical angles of incidence can be
identified, beyond which any power transfer to non-guided waves is forbidden,
i.e. all radiative losses are suppressed. In that case the input power is carried
away from the discontinuity exclusively by reflected semi-guided waves in the
input slab, or by semi-guided waves that are transmitted into other outgoing slab
waveguides. Vectorial equations on a 2-D cross sectional domain apply. These are
formally identical to the equations that govern the eigenmodes of 3-D channel
waveguides. Here, however, these need to be solved not as an eigenvalue problem,
but as an inhomogeneous problem with a right-hand-side that is given by the incoming
semi-guided wave, and subject to transparent boundary conditions. The equations
resemble a standard 2-D Helmholtz problem, with an effective permittivity in place
of the actual relative permittivity. Depending on the properties of the incoming
wave, including the angle of incidence, this effective permittivity can become
locally negative, causing the suppression of propagating outgoing waves. A series
of high-contrast example configurations are discussed, where these effects lead
to - in some respects - quite surprising transmission characteristics.

text: The exploration of FPGAs as accelerators for scientific simulations has so
far mostly been focused on small kernels of methods working on regular data structures,
for example in the form of stencil computations for finite difference methods.
In computational sciences, often more advanced methods are employed that promise
better stability, convergence, locality and scaling. Unstructured meshes are shown
to be more effective and more accurate, compared to regular grids, in representing
computation domains of various shapes. Using unstructured meshes, the discontinuous
Galerkin method preserves the ability to perform explicit local update operations
for simulations in the time domain. In this work, we investigate FPGAs as target
platform for an implementation of the nodal discontinuous Galerkin method to find
time-domain solutions of Maxwell's equations in an unstructured mesh. When maximizing
data reuse and fitting constant coefficients into suitably partitioned on-chip
memory, high computational intensity allows us to implement and feed wide data
paths with hundreds of floating point operators. By decoupling off-chip memory
accesses from the computations, high memory bandwidth can be sustained, even for
the irregular access pattern required by parts of the application. Using the Intel/Altera
OpenCL SDK for FPGAs, we present different implementation variants for different
polynomial orders of the method. In different phases of the algorithm, either
computational or bandwidth limits of the Arria 10 platform are almost reached,
thus outperforming a highly multithreaded CPU implementation by around 2x.
