Time Ordered Astrophysics Scalable Tools

TOAST

Time Ordered Astrophysics Scalable Tools (TOAST) is a software framework built to enable simulation and reduction of millimeter-wave astrophysical data consisting of timestreams from individual detectors. Although this package can run on a laptop, it has been designed to scale to high concurrency on the largest HPC systems. I am one of the lead developers of TOAST and work to ensure that it meets the requirements of current and future experiments.

TOAST is available both on PyPI and on Conda-Forge.


Background

The development of this software grew from the heritage of CMB analysis tools developed since the late 1990’s at LBNL.

Recent Work

  • Version 3.0 was just released, representing the culmination of years of work.

  • Implementation of a fast HDF5 data format with global indexing.
