Connor Browne, Nigel Tan, Scott Luedtke, Michela Taufer, and Brian Albright. Correctness Evidence for I/O Optimizations in VPIC-Kokkos: Preliminary Results

@article{browne_correctness_nodate,
title = {Correctness {Evidence} for {I}/{O} {Optimizations} in {VPIC}-{Kokkos}: {Preliminary} {Results}},
abstract = {Scientific input/output (I/O) optimizations require clear correctness evidence that application developers can review. We study deterministic export tests and scientist-vetted end-toend analyses within the Kokkos implementation of the Vector Particle-in-Cell (VPIC) application. These validations rely on different oracles and target different properties. This work in progress explores what kinds of correctness evidence should be provided alongside an application I/O optimization.},
