SUMMARY:Gotcha: A Function-Wrapping Interface for HPC Tools
DESCRIPTION:Workshop\nPerformance, Productivity, Workshop Reg Pass\n\nGotc
 ha: A Function-Wrapping Interface for HPC Tools\n\nPoliakoff, LeGendre\n\n
 This paper introduces Gotcha, a function wrapping interface and library fo
 r HPC tools.  Many HPC tools, and performance analysis tools in particular
 , rely on function wrapping to integrate with applications.  But existing 
 mechanisms, such as LD_PRELOAD on Linux, have limitations that lead to too
 l instability and complexity.  Gotcha addresses the limitations in existin
 g mechanisms, provides a programmable interface for HPC tools to manage fu
 nction wrapping, and supports function wrapping across multiple tools.  In
  addition, this paper introduces the idea of interface-independent functio
 n wrapping, which makes it possible for tools to wrap arbitrary applicatio
 n functions.
