SC15 BoF on "REPRODUCIBILITY OF HIGH PERFORMANCE CODES AND SIMULATIONS – TOOLS, TECHNIQUES, DEBUGGING"

EVENT TYPE: Birds of a Feather at SC15

DAY: Thursday, November 19, 2015

TIME: 12:15PM - 1:15PM

SESSION LEADER(S):

Michela Taufer (University of Delaware)

ABSTRACT: As applications are run on increasingly parallel and heterogeneous platforms, reproducibility of numerical results or code behaviors is becoming less and less obtainable. The same code can produce different results or occasional failures such as a crash on different hardware or even across different runs on the same hardware. This is due to many factors including non-determinism and the lack of numerical reproducibility with floating-point implementations. The target audience is application and tool developers interested in discussing case studies, tools, and techniques needed to address reproducibility on exascale systems. The format will be a panel of experts plus audience participation.
