Tool Evaluation Report Overview

• Evaluation report is coming along
• Course of action
• Write report of tools evaluated thus far
  (including HPC toolkit)
• Post report (5/31/2005) summary (6/2/2005)
• Update report summary after new tool
  evaluations as needed
• Originally summary presentation first, but want
  to push back
• Make sure the presentation is an accurate
  reflection of report

Tool Evaluation Report Outline

• Writing in the form of a conference/journal
  paper, although probably not enough publishable
  content
• Outline
• Abstract
• Introduction brief overview of project,
  motivation behind evaluating tools
• Evaluation methodology quick overview of
  evaluation strategy given by Hung-Hsun in report
  and refined by Adam Hans last semester
• Tool evaluations section follow general report
  outlines
• Installation usage overview
• Measurement overhead results
• Bottleneck analysis results
• Describe good/bad points of tool
• Discuss tool extendibility
• Give standard scores for each evaluation category
• Recommendations
• Which tool, if any, we should use and how
• Generate list of candidate tools we could/should
  possibly work with
• From list of candidate tools (possibilities that
  we should extend), rank on the following
  categories TBD
• A slightly edited version will go in our final
  report to the NSA
• Will probably need to do some extra work for TAU
  and Paradyn for overhead measurements and
  bottleneck analysis

Prototype Plan

• Emailed Sameer (TAU contact), found no support
  for GPSHMEM
• After tool report done, going to work with him to
  add GPSHMEM support to TAU
• Accomplishes two goals
• Strengthens relationship with TAU developers if
  we decide to use parts or all of TAU
• Demonstrates we are able to back up our design
  with code
• Plan of action
• Create PSHMEM wrappers for GPSHMEM
• Link PSHMEM wrappers with TAU and existing
  GPSHMEM code
• Work with Sameer for getting TAU ready to work
  with GPSHMEM
• Update ./configure script
• Add appropriate other code
• Note that TAU GPSHMEM will provide a basic but
  not very user-friendly or advanced way of
  analyzing SHMEM programs
