-# VORTEX
-VORTEX is a containerized web application for orchestrating data pipelines and workflows with an emphasis on GPU processing tasks.
-A data pipeline, or a data workflow as it is often referred to, defines a set of repeatable and automatable data processing operations.
-VORTEX is an especially useful tool for the prototyping, and deployment of these data workflows to support fast-paced missions in the fields of Machine Learning (ML) and Artificial Intelligence (AI).
