Subject: Software Release: ChASE v. 1.0.0

We are happy to announce the official release of the ChASE library
version 1.0.0.

ChASE (Chebyshev Accelerated Subspace Eigensolver) is an eigensolver
for the solution of the extremal spectrum of algebraic eigenproblems
generated by dense real symmetric and complex Hermitian
matrices. ChASE is a modern parallel C++ library. The library comes in
two versions and multiple builds. The current GPU build supports the
use of one or more GPU cards per computing node in a number of
flexible configurations. For more information please visit the
official online documentation at https://chase-library.github.io/ChASE

ChASE 1.0.0 has been extensively tested on both artificial problems
and eigenproblems extracted from electronic structure simulations up
to matrices of size N~5e+05 on a number of different supercomputing
clusters (Blue Waters, JUWELS, JUWELS Booster, JURECA-DC). The library
has been integrated in a Bether-Salpeter code
(https://doi.org/10.1016/j.cpc.2021.108081). ChASE is particularly
effective when used to solve for sequences of correlated eigenproblems
such as the one appearing from the Self-Consistent Field iterations of
Density Functional Theory codes.

ChASE library can be freely downloaded from
https://github.com/ChASE-library/ChASE

The development of the library is partly supported by the PRACE 6IP
WP8 project "Forward looking Software Solutions". The main development
team is the Simulation and Data Lab Quantum Materials located at the
Juelich Supercomputing Centre (Germany) supported by the Rudjer
Boskovic Institute (Croatia) for the multi-GPU implementation.

Subject: Firedrake Tutorial/ARCHER2, ONLINE, Aug 2021

The Firedrake team will be delivering an online training session on
23rd August 2021, 13:00 - 17:00 BST (12:00 - 16:00 UTC). This course
will introduce users to Firedrake, an automated system for the
solution of partial differential equations using the finite element
method. The training will also be an opportunity to get hands on
experience using ARCHER2, the UK national supercomputer.

Participants will gain experience writing Firedrake code to solve
PDEs, configure solvers and preconditioners for HPC and run the
resultant code on ARCHER2. Our course is aimed at researchers who have
little or no previous experience of using Firedrake and have a desire
to run on HPC.

Subject: Postdoc Position, Univ of Sao Paulo, Brazil

Post-Doc position in Modelling the Wheatley heart valve This project
involves the mathematical modelling of blood flow from the left
ventricle into and through a novel heart valve. The flow emerges from
the left ventricle as a spiral flow and enters the aortic valve. This
artificial valve consists of a titanium ring attached to a special
flexible polymer with a complex mathematical shape designed to rapidly
open during systole and close rapidly during diastole. It has three
leaflets (flaps) which may be modelled as curved elastic membranes.
Thus the modelling problem involves fluid/structure interaction, that
may be modelled by the immersed boundary method. The fluid (blood) may
require to be treated as non-Newtonian. The candidate will need to
have expertise in computational fluid dynamics, especially in CFD
packages for simulation of fluid-structure interactions or the
immersed boundary method, a good working knowledge of fluid simulation
package(s), and a high-level programing language. The candidate will
be based in Sao Carlos, Brazil, and will be required to spend some
time at Strathclyde University, Glasgow, UK., Covid permitting. The
post is initially for one year and can be renewed for another two
depending on performance. Starting date is expected to be from October
1st, 2021.  To apply, please send a CV and a reference letter to
