vis_cpu
Fast visibility simulator capable of running on CPU and GPU.
Description
vis_cpu
is a Python/numpy-based simulator for interferometer visibilities.
It models the sky as an ensemble of point sources, each with their own frequency
spectrum. Diffuse emission can be modelled by treating (e.g.) each pixel of a Healpix
map as a separate source. The code is capable of modelling polarized visibilities
and primary beams, but currently only a Stokes I sky model.
vis_cpu
includes a separate pycuda
-based implementation called vis_gpu
.
This is intended to keep feature parity with the vis_cpu
code to the greatest
extent possible.
An example wrapper for the main vis_cpu
simulator function is provided in this
package (vis_cpu.wrapper.simulate_vis()
).
Installation
Merely do pip install vis_cpu
. If you want to use the GPU functions, install
with pip install vis_cpu[gpu]
.
