After three years in the Royal Naval Scientific Service, Jack became a PhD student of Ron Mitchell's at the University of St Andrews, completing his degree while also employed as a Lecturer. He was one of the organisers of the numerical analysis conference at the University of St Andrews in 1965 which is regarded as the first of the biennial series of conferences which moved to Dundee in 1969, and continues now at the University of Strathclyde. Jack joined Ron Mitchell in Dundee in 1967, after a brief period at the University of Aberdeen. His research interests lay in the numerical solution of ordinary differential equations on which he supervised many PhD students and authored two highly-regarded text books. As well as research and teaching, Jack served as Head of Department and Dean of the Faculty of Science and Engineering. He was elected a Fellow of the Royal Society of Edinburgh in 1976. Jack was a very warm man and splendid company at all times. He had a wise head and was a fount of sound advice. He will be sadly missed by his former colleagues and many friends worldwide, and we are sure they would ant to join us in passing on our condolences to his wife Heather and their sons Ian and Roddy.

The design of the library separates the FMM-core (octree management, data structure, parallelism, ...) and the kernels that allow you to easily introduce new kernels. Highlights - Kernel independent method based on interpolation. We provide as well as a method based on Chebyshev and equispaced grid points. - Scalar and tensorial kernels - Different implementations for Poisson kernel are available : spherical expansion with rotation and BLAS optimizations, Chebyshev points and equispaced grid points. - Shared memory (OpenMP and StarPU (runtime system) and hybrid distributed/shared memory (MPI/OpenMP) The project Home page is https://gitlab.inria.fr/solverstack/ScalFMM where instructions for obtaining the source code are provided. Installation instructions and a User's Guide are also available. Contributions and feedback from users are welcome.

Due to multiple requests, we decided to extend the deadline for submitting an abstract to the meeting. The new deadline is April 30. The acceptance notification will be on May 7, and the final deadline for registration is the 15th of May.

The short course will review the peridynamic theory, and it will discuss various applications as well as related modeling and computational aspects. Students, postdocs, as well as early-career and senior researchers are welcome to participate. The short-course description is given below. Title: Peridynamic Theory of Solid Mechanics: Modeling, Computation, and Applications Instructors - Dr. John Foster ([log in to unmask]) The University of Texas at Austin - Dr. David Littlewood ([log in to unmask]) Sandia National Laboratories - Dr. Pablo Seleson ([log in to unmask]) Oak Ridge National Laboratory Peridynamics is a nonlocal reformulation of classical continuum mechanics, based on integral equations, suitable for material failure and damage simulation. In contrast to classical constitutive relations, peridynamic models do not require spatial differentiability assumptions of displacement fields, leading to a natural representation of material discontinuities such as cracks. Furthermore, peridynamic models possess length scales, making them suitable for multiscale modeling. This course will provide an overview of peridynamics, including its mathematical, computational, and modeling aspects. The course will also review advanced research topics and software in peridynamics, and it will include a hands-on tutorial on 3D simulation of solid mechanics problems. ------------------------------------------------------- From: Paul Breiding [log in to unmask] Date: April 12, 2018 Subject: Numerical Computing in Algebraic Geometry, Germany, Aug 2018 This message is to advertise the upcoming Summer School on Numerical Computing in Algebraic Geometry to be held at MPI MiS Leipzig, 13-17 August 2018.
