Public Talk
info  Heidelberg Chapter of SIAM Public Lecture "Navier-Stokes existence and uniqueness: how to win a $1 million Clay prize"Prof. David SilvesterNovember 27, 2019 / 16:15ECTS-Points: not yet determined
Abstract, registration & information:
In the year 2000, the Clay Mathematics Institute selected seven of the most important open problems in modern mathematics and offered a prize of $1 million for a solution to any of them. Nineteen years on, only one millennium prize problem has been solved. In this talk, Prof. David Silvester will discuss the Navier-Stokes existence and smoothness problem, one of the six remaining unsolved problems.

The Navier-Stokes equations are central to fluid dynamics and its applications to engineering and physics, describing viscous turbulent flow, e.g. of air around an aeroplane wing, weather patterns and blood flow through arteries. Despite the wide-ranging applicability of the Navier-Stokes equations, it is still not known whether they always admit smooth solutions, which contain no unphysical "blow-ups", or singularities.

info  AnyDSL: A Partial Evaluation Framework for Programming High-Performance LibrariesSebastian HackNovember 7, 2019, 16:15ECTS-Points: 0
Abstract, registration & information:
riting performance-critical software productively is still a
challenging task because performance usually conflicts genericity.
Genericity makes programmers productive as it allows them to separate
their software into components that can be exchanged and reused
independently from each other. To achieve performance however, it is
mandatory to instantiate the code with algorithmic variants and
parameters that stem from the application domain, and tailor the code
towards the target architecture. This requires pervasive changes to
the code that destroy genericity.

In this talk, I advocate programming high-performance code using
partial evaluation and present AnyDSL, a clean-slate programming
system with a simple, annotation-based, online partial evaluator. I
will show that AnyDSL can be used to productively implement
high-performance codes from various different domains in a generic way
map them to different target architectures (CPUs with SIMD units,
GPUs). Thereby, the code generated using AnyDSL achieves a performance
that is in the range of multi man-year, industry-grade,
manually-optimized expert codes and highy-optimized code generated
from domains specific languages.

info  Agile management approaches for research groupsManuela SchmidtDecember 4, 2019, 9:00-15:15ECTS-Points: 1
Abstract, registration & information:
Scrum is an agile framework within which people can address complex adaptive problems, while productively and creatively delivering products. Kanban uses a visual system for managing work as it moves through a process, allowing team members to see the state of every piece of work at any time.

Both of them are agile approaches to project management. Agile project management is one answer to the growing speed in which projects need to be delivered and the realization that many projects are not delivered as originally planned. This is especially true for projects with volatile or unclear requirements at project start.

Concepts like continuous improvement, fast feedback cycles, limiting work in progress and transparency can bring value to teams as well as to individuals.

During this workshop you will learn:

- What is Agile? Get an overview of agile principles, values, techniques and methods
- How to use Kanban for your personal use? Boost your productivity and get things done!
- How can Kanban be introduced to a team? Streamline work between team members and create transparency on status
- How can Scrum be adapted in an academic environment? Use a process framework to improve collaboration and knowledge-sharing between lab members and cut down your fixed meeting times

Program:

9:00-12:00

- Agile introduction - origins, mindset & term definition
- Introduction to Scrum Framework
- Introduction to Kanban
- Applying theory into practice (Part 1)
- Personal Kanban - how to gain focus and transparency in your daily work

13:00-15:15

- Applying theory to practice (Part 2)
- Kanban for teams - lightweight way to introduce an agile method to a team
- LabScrum - a process framework to manage work in academic scientific research

info  Workshop on analyzing stresses in moleculesVarious SpeakersNov 4-5, 2019ECTS-Points: not yet determined
Abstract, registration & information:
This workshop aims at discussing and devising new and unifying concepts to calculate and understand molecular stresses in complex materials. Such molecular stresses can stem from quantum chemical calculations, atomistic or coarse-grained Molecular Dynamics simulations. They could be inherent to the system, i.e. reflect intrinsic tension or pre-stress, or build up upon applying external mechanical perturbations.

In an informal workshop we will bring together experts from the relevant scientific areas, computational physics, materials science, and biological matter, and will leave room for a few contributed talks from participants as well as many discussions among speakers and participants. There is the possibility to participate in a small practical workshop on force distribution analysis (FDA).

The workshop is completely free of charge.
