ExaHyPE (exahype.eu) is an open source simulation engine to solve systems of hyperbolic equation systems. It uses the ADER-DG scheme and is built on top of dynamically adaptive meshes and a customisation engine to yield effective, parallel code. ExaHyPE is written in a way that most computer science aspects as well as most of the numerics are hidden away from the user. Users plug in their PDE formulation (as flux and eigenvalues) into the engine and then delegate all further work to ExaHyPE. For this workshop, we invite existing users and interested potential users alike to join us for four days. Our idea is that users try out the engine, while some developers are around, i.e. they start the week with a problem given as PDE in mind and go home with a working first prototype built on top of ExaHyPE.

What you have to bring along:

• Your hyperbolic PDE in a first order formulation.

• A laptop that you can use to develop a new simulation on top of ExaHyPE.

Supercomputer Access:

• Remote access to a supercomputer will be provided for the duration of the workshop.

• The compute and data resources are provided by the Leibniz Supercomputing Centre (www.lrz.de).

Time and location:

• The workshop takes place at Grey College at Durham University in the Holgate Main room.

• We start with a reception in the evening of Monday, 22 April 2019 and wrap up the workshop in the morning of Friday, 26 April 2019.

• The workshop is free of charge.

• We can provide a limited number of travel grants to European partners, if you would like to apply for a travel grant please send an email to reinarz@in.tum.de or tobias.weinzierl@durham.ac.uk.

Accomodation:

  Oliver Belcher: Sensing, Territory, Population: Computation, Embodied Sensing, and Hamlet Control in the Vietnam War
  
  Abstract: This presentation analyses a mid-twentieth century computerized pacification reporting system, the Hamlet Evaluation System (HES), used by the US military to measure hamlet-level security and development trends in the Vietnam War. The significance of the HES was its capacity to translate US Military Advisor observations of Vietnamese hamlet life into a machine-readable computer format used by US military systems analysts to disclose 'patterns of life.' I show how US Military Advisors operated as 'embodied sensors' within the HES, producing a distinctive location-based event ontology - a 'view of below' - accompanied by rudimentary digital maps in-formation from incoming hamlet-level observation streams. I argue that acts of translating the rich texture of hamlet and village life into an objectified information format constituted a unique form of 'epistemic violence,' rooted not so much in the narrative subjection of the 'Other,' but in the pure abstraction of life into a digitally stored data trace.
