SUMMARY:A Compiler and Profiler Based Tool for Querying HPC Application Ch
 aracteristics
DESCRIPTION:Workshop\nCollaborative Environments, Reproducibility, System 
 Administration, System Software, Tools, Workshop Reg Pass, HPC\n\nA Compil
 er and Profiler Based Tool for Querying HPC Application Characteristics\n\
 nWelch\n\nEmerging HPC platforms are becoming extraordinarily difficult to
  program as a result of complex, deep and heterogeneous memory hierarchies
 , heterogeneous cores, and the need to divide work and data among them. Ne
 w programming models and libraries are being developed to aid in porting e
 fforts of application developers, but substantial code restructuring is st
 ill necessary to fully make use of these new technologies. To do this effe
 ctively, these developers need information about their source code charact
 eristics, including static and dynamic (e.g. performance) information to d
 irect their optimisation efforts and make key decisions. On the other hand
 , system administrators need to understand how users are using the softwar
 e stack and resources on their systems to understand what software they ne
 ed to provide to improve the productivity of the users on a platform.\n\nI
 n this presentation, we describe a tool that combines compiler and profile
 r information to query performance characteristics within an application o
 r across multiple applications on a given platform. Static and dynamic dat
 a about applications are collected and stored together in an SQL database 
 that can be queried by either a developer or a system administrator. We wi
 ll demonstrate the capabilities of this tool via a real-world example from
  application-driven case studies that aims at understanding the use of sci
 entific libraries on a routine from the molecular simulation application C
 P2K.
