Subject: A History of MATLAB, ACM Proceedings for HOPL IV

"A History of MATLAB", a 67-page paper that Jack Little and I have
written, has been published by the ACM in the proceedings of HOPL IV,
the Fourth ACM SIGPLAN History of Programming Languages Conference,
https://dl.acm.org/doi/10.1145/3386331. The conference, planned for
mid-June in London, has been postponed, but the proceedings have
arrived on schedule.

PACMPL in the ACM Digital Library is published with open access, so
the HOPL IV papers are freely available to ACM members and nonmembers
alike. In addition to MATLAB, the 19 papers in the HOPL IV volume
include histories of APL, C++, Clojure, Fortran coarrays, D, Emacs
Lisp, F#, Groovy, JavaScript, LabVIEW, Logo, Cambridge Polish,
Objective-C, Oz, R, S, Smalltalk, ML, and Verilog HDL.

Subject: MAGMA is now on BitBucket using git

Due to the Mercurial support being discontinued on BitBucket starting
July 1st 2020, the public repository of the MAGMA library is now
converted to the git version control system. Active developers and
users of the library should switch to the new repository effective
immediately. All branches, issues, and release tags are also
converted. To clone a clean copy of MAGMA:

git clone git@bitbucket.org:icl/magma.git

The MAGMA library provides many dense and sparse linear algebra
algorithms for heterogeneous HPC systems that take advantage of many-
core architectures such as GPUs. For more information, please visit:

Machine learning (ML) is currently undergoing a massive expansion, due
to the unprecedented availability of large amounts of data and
computational power. The last decade has seen tremendous improvements
in ML methods and achievements in many application areas including
(bio-) medical sciences, computer vision and finance to name but a
few. Remarkably, while ML relies on mathematical models and tools,
many ML algorithms do not have a rigorous mathematical foundation. One
reason for this is that ML has been historically developed as a
subfield of computer science rather than mathematics. Fundamental
analysis questions are open, such as convergence and convergence
rates, or the topology and geometry with which data should be
studied. It is essential that the mathematical community contributes
to ML and provides a solid underpinning of ML methods. This Symposium
will advocate the connection between ML and many mathematical
disciplines, such as numerical analysis, inverse problems,
optimisation, statistics, optimal transport, dynamical systems and
partial differential equations, in order to shed light into the
mysterious mathematical pathways of ML.

Subject: Postdoc Position, Computational Fluid Dynamics

Summary: The Center for Research in Mathematical Sciences Applied to
Industry (CEPID-CeMEAI) at University of Sao Paulo opens a
post-doctoral research position in Computational Fluid Dynamics. The
selected candidate will work at Institute of Mathematical and Computer
Sciences of the University of Sao Paulo in Sao Carlos/SP, Brazil. Sao
Paulo Research Foundation provides the financial support with a
monthly salary of BRL 7.373,10 (after taxes). Financial support can
also be provided to cover transportation expenses to move to Sao
Carlos - Brazil. An extra grant is also provided to cover
participation in highly relevant conferences and workshops, as well as
research trips (limited to 15% of the annual amount of the
fellowship). The position is for one year. Project: Multiscale
preconditioners for the simulation of petroleum
reservoirs. Supervisor: Fabricio Simeoni de Sousa Description: The
simulation of large oil reservoirs, such as those found in the
pre-salt layers of the Brazilian coast, require the use of
computational meshes of billions of elements, a scale that cannot be
handled efficiently with current commercial simulators. The use of
multiscale domain decomposition methods have shown great scalability
potential that allows an efficient parallelization of meshes with such
order of magnitude. Among the several methods found in the literature,
the Multiscale Robin Coupled Method (MRCM) has become a reference in
the area thanks to great flexibility introduced by the Robin boundary
conditions and the independent choice of interface spaces. The present
project aims the development and implementation of an efficient
preconditioner based on the MRCM in a high performance computing
environment taking advantage of its modern hybrid multicore
architecture. The final goal is to accelerate large-scale simulators
capable of handling meshes with billions of elements, required for the
accurate simulation of large petroleum reservoirs. Professor Sousa
will lead the research, jointly with his research group.
Requirements: Applicants should have PhD in Applied Mathematics,
Computer Sciences, or related fields, with experience in Computational
Fluid Dynamics. Experience in the implementation of multiscale methods
for reservoir simulation is required. We also require experience with
order reduction methods for subsurface flows problems and experience
in high performance computing with C/C++ languages. At least two
scientific journal paper published in the last 5 years in the field of
multiscale methods for reservoir simulation are required. Candidates
must have got their PhD in the last 5 years to be considered for this
position. Application: Please send your application before July 15,
2020 to: Dr. Fabricio Simeoni de Sousa (f.s.sousa@usp.br). Please

RSEs to develop and grow their skills, build new collaborations and
engage with RSEs worldwide. Until we can meet again in person, SORSE
(pronounced "Source"), will bridge the gap and be the source of
interesting and engaging events.

This is an open call to all RSEs and anyone involved with research
software, worldwide, to propose talks, workshops and other types of
online events.

The Call for Contributions form will remain open continuously and
there will be a rolling deadline at the end of the last day (UTC) of
