A many-core capable lightweight in situ visualization and analysis infrastructure for multi-physics HPC simulations.


Strawman is no longer being actively developed. ALPINE Ascent is an evolution of and a successor to Strawman.


Strawman is a system designed to explore the in situ visualization and analysis needs of simulation code teams running multi-physics calculations on many-core HPC architectures. It provides rendering pipelines that can leverage both many-core CPUs and GPUs to render images of simulation meshes.

Strawman focuses on ease of use and reduced integration burden for simulation code teams:

  • It does not require any GUI or system graphics libraries.
  • It includes integration examples which demonstrate how to use Strawman inside of three different HPC simulation proxy applications.
  • It provides a built-in web server that supports streaming rendered images directly to a web browser.
