SUMMARY:Code Optimization
DESCRIPTION:FuzzyFlow: Leveraging Dataflow to Find and Squash Program Opti
 mization Bugs\n\nThe current hardware landscape and application scale is d
 riving performance engineers toward writing bespoke optimizations. Verifyi
 ng such optimizations, and generating minimal failing cases, is important 
 for robustness in the face of changing program conditions, such as inputs 
 and sizes. However, i...\n\n\nPhilipp Schaad, Timo Schneider, Tal Ben-Nun,

 ntime Composition of Iterations for Fusing Loop-Carried Sparse Dependence\
 n\nDependence between iterations in sparse computations causes inefficient
  use of memory and computation resources. This paper proposes sparse fusio
 n, a technique that generates efficient parallel code for the combination 
 of two sparse matrix kernels, where at least one of the kernels has loop-c
