Clicker polling is a well-established method for increasing active participation of students in lectures and has also been associated with improving students' overall learning experience. Devising good questions can be a huge challenge, and although extensive collections of clicker questions are available for introductory courses in calculus and linear algebra, there is very little available that focuses on numerical analysis. These clicker questions are written in LaTeX so that they can be easily presented as slides, or else incorporated into existing LaTeX lecture notes. The question bank has been released under the Creative Commons ShareAlike (CC BY-NC-SA) license which allows anyone free access to use, copy/redistribute, and adapt/remix the materials. The complete resource can be downloaded from this web page http://www.sfu.ca/~jstockie/NAclicker/ which includes LaTeX source code for all questions (and partial solutions), macro definitions for displaying the questions in various formats (including beamer and non-beamer slide formats), image files for all plots and graphics, and the Matlab code used to produce them. This page also has a link to a preprint which serves as a "how-to guide" of sorts and also summarizes the results of a student satisfaction survey held in a "face-to-face" class. With the recent switch in many universities to on-line learning, instructors may also find these clicker questions a useful tool for better engaging students in a remote setting. The question bank is by no means complete and there is clearly room for improvement in terms of providing more solutions, and expanding the topics covered. We welcome all comments, corrections and especially additions to this open educational resource.

This was by no means an easy decision. The tentative date for MOPTA 2021 is August 2-4, 2021. The MOPTA-AIMMS competition will proceed as planned but will be virtual. The finalists will be contacted in the next couple of weeks and presentations will be on-line and made freely available. Thank you very much for your understanding. ------------------------------------------------------- From: Philipp Neumann [log in to unmask] Date: May 29, 2020 Subject: Computer Scientist Position, High Performance Computing, Hamburg This permanent position is hosted at the chair for high performance computing (HPC), Prof. Philipp Neumann, at Helmut-Schmidt-University Hamburg.

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 ([log in to unmask]). Please indicate "CEPID Postdoc - Multiscale Methods" in the subject line.
