SUMMARY:Guarding Numerics Amidst Rising Heterogeneity
DESCRIPTION:Workshop\n\nGuarding Numerics Amidst Rising Heterogeneity\n\nG
 opalakrishnan, Laguna, Li, Panchekha, Rubio-Gonzalez...\n\nNew heterogeneo
 us computing platforms---especially GPUs and other accelerators---are bein
 g introduced at a brisk pace, motivated by the goals of exploiting paralle
 lism and reducing data movement. Unfortunately, their sheer variety as wel
 l as the optimization options supported by them have been observed to alte
 r the computed numerical results to the extent that reproducible results a
 re no longer possible to obtain without extra effort.  Our main contributi
 on in this paper is to document the scope and magnitude of this problem th
 at has not received much attention.  We propose a taxonomy of sub-topics a
 nd details under each, and close with a summary table of these discussions
 .  Given the magnitude of maintaining reliable information, we issue a cal
 l for community action, helping us maintain a website containing curated i
 nformation.\n\nTag: Online Only, Correctness, Heterogeneous Systems, Relia
