Subject: Gary Leaf

Dr. Gary Kristian Leaf, a member of the Mathematics and Computer
Science Division at Argonne National Laboratory, passed away on
January 13, 2020, at the age of 84.

Gary graduated with a doctorate in mathematics and a master's in
physics from the University of Illinois Urbana- Champaign.  After
working for two years at the University of Chicago, Gary moved to his
permanent home at Argonne National Laboratory in 1963. He worked at
Argonne until 2019, a total of 56 years; his plans to return to work
were interrupted by his death. Despite battling retinitis pigmentosa,
a condition that rendered him legally blind, Gary continued to do
mathematics and publish well past his official retirement age.

Gary's passion was applying mathematics principles to solve a wide
range of problems in science and engineering. In the 1960s and 1970s,
he focused on modeling problems in nuclear reactor physics and
participated in the development of two important simulation codes,
PERC and ANL-CANDID. His work (along with collaborators) during the
1970s included the numerical solution of the neutron transport
equation, multigroup diffusion equations, and applications of the
newly successful finite element methods to problems in reactor
physics. He participated in the development of a third reactor physics
code, DISPL, that extended the range of the previous codes to simulate
both kinetics and diffusion problems.

From the 1980s to the mid-1990s, Gary broadened his areas of work and
focused on developing numerical techniques for solving problems in
fluid dynamics, combustion, wavelets, and chaotic dynamics among other
topics. In the mid-1990s, Gary developed a keen interest in
application of mathematics to physical systems, in particular to
materials science. His collaborations with Argonne's Materials Science
Division lasted decades and included work in superconductivity and
micromagnetics.  He co-authored papers on a broad range of topics
including parallel adaptive multigrid, wavelets, sedimentation, and
one of the first papers on adjoint- based data assimilation. In one of
his last publications, he collaborated with the Department of
Physiology and Molecular Biology at the Rush University Medical
Center.  There Gary worked on mathematical modeling and simulation of
ion channels --- doughnut-shaped proteins residing in the cell
membrane and regulating the flow of ions in and out of the cell. In
his work he actively used the latest supercomputers available at
Argonne, including Intel's Theta system.

Throughout his professional life, Gary touched and deeply impacted
many lives --- as a mentor, as a colleague,and as a friend. Gary was
very supportive of the work of early career staff and showed great
interest in learning more about their projects and always asked
challenging questions about their research topics. Gary-s thirst for
knowledge, his work ethic, and his undying curiosity to learn more
were great sources of inspiration to multiple generations of research
staff. Gary worked with a number of graduate students, postdocs, and
collaborators within the laboratory and academia, all of whom have
fond memories of their time with Gary.

Subject: Announcing FEAST Eigensolver v4.0

The FEAST library package represents an unified framework for solving
various family of eigenvalue problems and achieving accuracy,
robustness, high-performance and scalability on parallel
architectures.  FEAST is both a comprehensive library package, and an
easy to use software. Its originality lies with a new transformative
numerical approach to the traditional eigenvalue algorithm design -
the FEAST algorithm. The algorithm gathers key elements from complex
analysis, numerical linear algebra and approximation theory, to
construct an optimal subspace iteration technique using approximate
spectral projectors.  It belongs to the family of contour integration
eigensolvers which involves solving independent linear systems along a
complex contour.  FEAST v4.0 is a major upgrade. The entire code has
been re- implemented using an inverse residual iteration algorithm
allowing the linear systems to be solved with very low accuracy (in
single precision) with no impact on the FEAST double precision
convergence rate. As a result, v4.0 is on average 3 to 4 times faster
than v2.1 and v3.0 using new default optimization parameters (v2.1 has
been featured as Intel- MKL's principal HPC eigensolver since 2013).

FEAST v4.0 package include the following (many new) features:
1- Support for Hermitian and non-Hermitian systems (Standard or
2- Support for Polynomial systems such as quadratic, cubic, quartic, etc.
3- Finding eigenpair within a search contour (normal mode); Finding
extreme eigenvalues (lowest/largest);
4- Mixed precision (single precision operations leading to double
precision final results);
8- IFEAST- FEAST w/o factorization for sparse drivers;
9- PFEAST- FEAST using 3 levels of MPI parallelism (with MPI solvers);
5- Two libraries: SMP version (one node), and MPI version (multi-nodes);
6- Flexible Reverse communication interfaces (RCI);
7- Ready to use Driver interfaces for dense, banded, sparse  formats;
10- Large number of useful options, expert mode, examples, and

Subject: New preCICE Release v2.0

We are happy to announce a new preCICE release v2.0.

preCICE is a coupling library for partitioned multi-physics
simulations, including, but not restricted to fluid-structure
interaction and conjugate heat transfer simulations. Partitioned means
that preCICE couples existing programs (solvers) capable of simulating
a subpart of the complete physics involved in a simulation. This
allows for the high flexibility that is needed to keep a decent
time-to-solution for complex multi-physics scenarios. Ready-to-use
adapters for well-known commercial and open-source solvers, such as
OpenFOAM, deal.II, FEniCS, SU2, or CalculiX, are available. preCICE is
an open-source software under the LGPL3 license.

We decided to move to v2.0 to clean up some old baggage. Users need to
change a few things in their applications to move to v2.x, but it's
worth it, many things will get much simpler. To help moving, we
prepared a porting guide:

A few highlights:

- The Python bindings are now really pythonic and available through
- We now also have Matlab bindings.
- Configuration of OpenFOAM cases now directly use an OpenFOAM dictionary.
- We did several optimizations to better support very large cases.

Subject: EoCoE Webinar on MLD2P4, Feb 2020

The EoCoE team will give the second webinar of 2020 on Linear Algebra
software tools, taking place on February, 24, 2020 and starting at 3
PM.  During this webinar, Pasqua D'Ambra, Senior Research Scientist at
the National Research Council of Italy, will present MLD2P4
(MultiLevel Domain Decomposition Parallel Preconditioners Package
based on PSBLAS), which provides efficient and easy-to-use
preconditioners in the context of the PSBLAS (Parallel Sparse Basic
Linear Algebra Subprograms) computational framework. The package,
whose features are constantly updated within the Energy-Oriented
Center of Excellence (EoCoE) European project, includes multilevel
cycles and smoothers widely used in multigrid methods. A purely
algebraic approach is applied to generate coarse-level corrections so
that no geometric background is needed concerning the matrix to be
preconditioned.  The webinar will present the main features of the
package, and example of usage of the main APIs needed to setup the
preconditioner, together with its application within the Krylov
solvers available from PSBLAS. Some results on test cases relative to
the EoCoE application areas highlight how the PSBLAS/MLD2P4 software
framework can be used to obtain highly scalable linear solvers.  For
those of you who wish to participate, please register on the dedicated

Subject: PhD Position, Wind turbine Navier-Stokes CFD, Lancaster Univ

This cross-disciplinary project aims to substantially reduce Floating
Offshore Wind Turbine (FOWT) development uncertainty, which limits the
full exploitation of global wind energy resources.  Unlike
fixed-bottom turbines, which cannot be installed deeper than 50
meters, multi-megawatt FOWTS can be used at any depth. However,
further from the coast is a more extreme environment, with FOWT
stability, efficiency and durability determined by the interaction of
aerodynamic loads on rotor and tower, and wave- and current-induced
loads on floater. Reliably assessing these loads is paramount to
designing the system control tasked with guaranteeing operational
targets. The current uncertainty affecting low-fidelity engineering
codes for FOWT development presents a significant challenge for the
long-term success of FOWTs. No research worldwide has yet developed
blade-pitch control functionalities in Navier-Stokes (NS) CFD
simulations required for conclusive reliability assessment and
improvement of modern FOWT engineering codes.

The project will address this challenge by developing novel
high-performance-computing-enabled NS-CFD functionalities in the FOWT
NS-CFD research code COSA. Development tasks are: a) implement
accurate sliding mesh functionalities in COSA to simulate individual
blade pitch control responding to wind gusts and wave-induced turbine
oscillations, b) develop Graphic-card-unit (GPU) computing into the
existing distributed-memory COSA. Objectives are: a) study
design-driving FOWT regimes using state-of-the-art engineering codes
and new GPU-supported and pitch-control-enabled FOWT COSA code, b)
analyse key FOWT physics, c) assess shortfalls of engineering codes
and correct their low-fidelity models. Further information is
