DISTRIBUTED AND PARALLELIZED VISUALIZATION FRAMEWORK

A technique for rendering database data in visualized form using a distributed computer system including a plurality of networked worker nodes each including a graphics processing unit (GPU) is disclosed. The technique includes receiving, at a head node, a user request to render data, forwarding the request to the worker nodes, processing, in parallel, by the worker nodes, chunks of respective shards of data to be rendered. The technique also includes merging, in parallel, by each of the worker nodes, initial images formed by the processing within respective shards, to form a plurality of integrated images, merging, in parallel, respective integrated images to form worker node images, and transmitting respective worker node images to the sink node. The technique also includes merging the worker node images to form a final image, converting the final image to an output image, and providing the output image to the user.
