IHP Trimester Workshops programme 2018

Computational Methods

The "Computational Methods” workshop is the final of three workshops taking place during the Fall 2018 Trimester on "Analytics, Inference, and Computation in Cosmology", held at the Institut Henri Poincaré in the latin quarter of Paris.

The general theme of the three-month event is to ask the questions: do we have the right methods and tools in place for the next decade in cosmology? What are the key challenges and promising new avenues to solve them? The "Computational Methods"" workshop will focus on the unique computational challenges of numerical modeling of the universe at the level of precision required for the next generation of surveys. Analytical and Statistical methods are the focus of two other workshops.

This 5-day workshop will take place from the 26th until the 30th of November 2018. The program will consist of 45-minute invited talks (three per half day, with Wednesday afternoon off and an early close on Friday) leaving plenty of time for discussion and collaboration. Some speakers will be specifically invited to focus on challenges, that is on identifying the main open methodological problems that must be overcome to raise the quality and speed of computational cosmology to the level of upcoming data sets in certain subfields of cosmology.

We have identified advances and challenges in computational methodology in the following areas as the main topics for this workshop:

  • N-body simulation and Vlasov solvers
  • Fast approximate solvers
  • Generation of mock Surveys
  • Hydrodynamical simulations
  • Statistical properties of galaxies
  • Subgrid physics
  • Radiative Transport
  • Computing Beyond Lambda-CDM Cosmology
  • Fast transforms and multipole methods
  • Simulating the Simons Observatory and CMB stage 4
  • Computing the Early Universe
  • To help inspire discussions and collaborations during this workshop and throughout the trimester we encourage all speakers, not just those giving "challenge talks", to highlight important open questions as well as present solutions.
