THIS IS A MAJOR RELEASE, fruition of six years of development, which brings many innovative features. Thread management is now fully dynamic. Efficient multi-threaded versions of many time-consuming algorithms have been coded. These algorithms concern the SCOTCH (formerly) sequential library, as well as the PT-SCOTCH MPI-based library (which now provides hybrid parallel algorithms, mixing threads and MPI). New objects called "contexts" allow users to launch SCOTCH tasks concurrently. More here : https://www.labri.fr/perso/pelegrin/scotch/ IMPORTANT: YOUR HELP IS NEEDED: in 2022, the SCOTCH project will turn 30. In order to perpetuate software development around SCOTCH, a consortium is being created, to pool development goals and investments from its members so as to fund engineering staff to carry out strategic R&D. We are currently identifying ambitious key parties interested in joining the consortium. This is a great opportunity for people and organizations having needs in fast and efficient graph partitioning to support and ensure the sustainability of the Scotch software for its users all around the world. Would Scotch (prospective) users be so kind as to fill the questionnaire below? https://framaforms.org/feedback-on-the-scotch-software-1640960422 The preparatory document for the Scotch consortium is available here: https://framaforms.org/sites/default/files/forms/files/scotch_consortium_preparation_20211231.pdf ------------------------------------------------------- From: Kris ONeill [log in to unmask] Date: December 30, 2021 Subject: New Books, Mathematical Elasticity, Volumes I-III Mathematical Elasticity, Volumes I-III by Philippe G. Ciarlet The Mathematical Elasticity set contains three self-contained volumes that together provide the only modern treatise on elasticity. They introduce contemporary research on three-dimensional elasticity, the theory of plates, and the theory of shells. Each volume contains proofs, detailed surveys of all mathematical prerequisites, and many problems for teaching and self-study. An extended preface and extensive bibliography have been added to each volume to highlight the progress that has been made since the original publication. The first book, Three-Dimensional Elasticity, covers the modeling and mathematical analysis of nonlinear three-dimensional elasticity. In volume two, Theory of Plates, asymptotic methods provide a rigorous mathematical justification of the classical two-dimensional linear plate and shallow shell theories. The objective of Theory of Shells, the final volume, is to show how asymptotic methods provide a rigorous mathematical justification of the classical two-dimensional linear shell theories: membrane, generalized membrane, and flexural. These classic textbooks are for advanced undergraduates, first-year graduate students, and researchers in pure or applied mathematics or continuum mechanics. They are appropriate for courses in mathematical elasticity, theory of plates and shells, continuum mechanics, computational mechanics, and applied mathematics in general.

(This is in contrast with it being offered as a hybrid event as was originally announced.) The decision was based on several factors including the onset of the Omicron variant of COVID-19 which makes travel in February an unknown. The online event will run February 23-26, 2022, as originally planned. For more details, please see the conference website: https://internationalmeshingroundtable.com/ . Updated Research Abstract, Research Notes and Poster Session: Moving online allows greater flexibility with deadlines for Research Abstracts (single-paragraph abstract), Research Notes (short-form 4 page papers) and Poster Session entries. These have been updated to January 14, 2022. Submissions to all three will be accepted up until this date, even if a notification of commitment has not been received. Please see https://www.internationalmeshingroundtable.com/research- notes/ and https://www.internationalmeshingroundtable.com/poster/ Meshing Contest Deadline: The details of the meshing contest are online, at https://www.internationalmeshingroundtable.com/meshing-contest/. The deadline for submission is February 4, 2022. ------------------------------------------------------- From: Svetozar Margenov [log in to unmask] Date: December 30, 2021 Subject: Numerical Solutions of Fractional Diff Eqs, Bulgaria, Jun 2022 The Second International Workshop "Numerical Solution of Fractional Differential Equations and Applications" (NSFDE&A'22) will take place in June 8 - 13, 2022, Sozopol, Bulgaria: http://parallel.bas.bg/Conferences/NSFDE&A2022/ The workshop is organized by the Institute of Information and Communication Technologies, Bulgarian Academy of Sciences and MIV Consult Ltd. in cooperation with the Bulgarian Section of SIAM, and the Center of Excellence on Informatics and ICT The NSFDE&A'22 will be held in Sozopol (ancient Apolonia), a picturesque town on the Black Sea coast, 36 km south of Bourgas. The Bourgas International Airport is 50 km to the north from Sozopol. The workshop will be organized as a hybrid event: a) presence at the conference venue in Sozopol; and b) online through the free (for the participants) software platform Zoom. Specific topics of interest (but not limited to) are the following: (i) fractional in space problems; (ii) fractional in time problems; (iii) multigrid solvers; (iv) coupled problems; (v) phase separation and image segmentation; (vi) parallel algorithms and HPC tools; (vii) applications in science and engineering.

With this school we want to bridge the divide between simulation practice and fundamental research in electronic-structure methods. It is intended for both researchers with a background in mathematics or computer science willing to be introduced to the numerical aspects of electronic-structure calculations, as well as physicists or chemists interested in modern software development methodologies and the mathematical background of DFT. As part of the school we will discuss the methodology underpinning modern DFT approaches and there is ample time to conduct numerical experiments and simulation exercises in hands-on sessions. For the latter we will introduce participants to the Julia programming language as well as to DFTK, an accessible (less than 7000 lines) DFT code equipped with state-of-the-art performance to treat systems with 1000 electrons. See the school's website https://school2022.dftk.org/ for more details and https://school2022.dftk.org/registration to register. Note that the school is free of charge and there is limited funding to contribute towards local expenses of junior researchers. ------------------------------------------------------- From: Elfriede Friedmann [log in to unmask] Date: January 03, 2022 Subject: Postdoc Position, Applied PDEs, Kassel Univ We open a full postdoc position for 3 years with with the possibility of academic qualification.
