  MagAO-X is an extreme adaptive optics (ExAO) instrument for the Magellan Clay
6.5-meter telescope at Las Campanas Observatory in Chile. Its high spatial and
temporal resolution can produce data rates of 1 TB/hr or more, including all AO
system telemetry and science images. We describe the tools and architecture we
use for commanding, telemetry, and science data transmission and storage. The
high data volumes require a distributed approach to data processing, and we
have developed a pipeline that can scale from a single laptop to dozens of HPC
nodes. The same codebase can then be used for both quick-look functionality at
the telescope and for post-processing. We present the software and
infrastructure we have developed for ExAO data post-processing, and illustrate
their use with recently acquired direct-imaging data.
