Hi,

Thanks very much for the info about the talk. I'm very interested in the topic, but unfortunately I have another commitment at the same time. Will the talk be recorded?

Thanks very much and have a nice weekend!

Alex

Hello all,

In next week's ET call slot 9:00 CST Adam Peterson (LBL) will present on:

Symbolic Code Generation for Tensorial PDEs with Applications to Black holes, Cosmic Strings, and Quantum Fields

Abstract: I will present the ongoing developments in code generation techniques for producing executable code blocks representing tensorial PDEs as encountered in numerical relativity. Specifically I will discuss code generation applications to AMReX based simulations of various systems including black hole mergers, cosmic string collapse, and more exoticly, lattice quantum field theories. I will demonstrate specific cases where symbolic tensorial expressions can be written in SymPy or Mathematica and then expanded into code blocks in C++ or Fortran. Simulations of black hole mergers and cosmic string collapse produced entirely from code generated applications will be shown with comparisons to standard testbeds in numerical relativity. Finally, a discussion of current and future developments will be presented.

This will be an informal presentation, with questions, discussion and technical talk welcome and encouraged.
