This document is a submission to the CG&A special issue on High Performance Visualization and Analysis. The paper, titled "VTK-m: Accelerating the Visualization Toolkit for Massively Threaded Architectures," describes a new toolkit named VTK-m that supports efficient scientific visualization algorithms on multicore and manycore devices.

VTK-m is developed from a collaboration between many DOE researchers and is the conglomeration of multiple previous threaded visualization toolkits. This paper describes how the pieces of the previous-generation toolkits come together. We also provide several example usages of the new toolkit to demonstrate its utility and flexibility.

The paper is written at a high level to be accessible to a range of CG&A readers. We discuss the background of the problem and clearly describe the challenges of the work before explaining our solution.
