We'll discuss the VTK-m project, an HPC library for scientific visualization algorithms, and describe how it changed over the past three years. Part of the Exascale Computing Project, VTK-m is designed around fine-grained concurrency and an abstraction between the low-level hardware architectures and the data-parallel high-level code. This allows developers to write small worklets that can be executed on any hardware. We'll examine significant performance and development lessons learned since the VTK-m project began and talk about the challenges we see ahead.
