This repository implements both F- and X-engines for a GPU-based correlator, developed for the MeerKAT Extension Radio Telescope by the South African Radio Astronomy Observatory (SARAO). A B-engine for beamforming is planned, but not yet included.
Detailed documentation can be found on
readthedocs, including a guide for
development.
The documentation sources are in the doc/ folder, and can be
built with Sphinx.
The following requirements are what we consider to be the minimum for making use of this module. Listed are the tested / supported software versions and hardware generations. Other platforms may well work, but have not been tested.
- An Nvidia GPU. For the XB-engine, it needs to be of compute capability 7.2 or greater and have tensor cores.
- Mellanox OFED Drivers v5.3.1 for ibverbs functionality. (Any v5+ should work.) For best performance, ibverbs is recommended.
- Ubuntu 22.04
- Python 3.10.
- CUDA version 12.0.1. (Most early development was done using 10.1, which may still work but has not been tested for some time.)
