Paraver

http://www.cepba.upc.es/paraver/index.html

Pros:

• Performance visualization tool
• performance views: timelines, textual, statistics
• 3D/2D analysis module
• Strong documentation + David :)
• Free (need to get a licence) 
• Done especially for OpenMP+MPI apps

Cons:

• Seems complicated
• We don't have that much time (REU students I mean)
• Apparently doesn't run on x86
  

Vampir

http://www.vampir-ng.de/

Pros:

• Good, stable GUI

• Provides a large number of view options

• Shows call trees
• Powerful
• Can do binary instrumentation
  

Cons:

• Offers no user guidance on analyzing data
  
• Only does MPI
• Solid learning curve
• $200 per license
  

TAU

http://www.cs.uoregon.edu/research/tau/home.php

Pros:

• TAUs profile visualization tool, paraprof, provides graphical displays of all the performance analysis results, in aggregate and single node/context/thread forms. [Website]
  

• TAU can generate event traces that can be displayed with the Vampir, Paraver or JumpShot trace visualization tools. [Website]
  

• Free license, just have to request a copy trough email

• OpenMP

• "Will have support of g95 in two months" (by insider)

• Already used for WRF

• lots of documentation

Cons:

• No g95 Support!
• Instrumenting is tedious and error prone
• Steep learning curve
• Many features depend on other software
  

gprof

http://www.cs.utah.edu/dept/old/texinfo/as/gprof_toc.html

Pros:

• Free user license

• OpenMP

• Good Tutorial on the web by GNU
• Quick and Easy to use
  

• Already works on our system!

Cons:

• Doesn't scale well to large jobs
• No useful MPI or I/O information
• Don't provide wall-clock time information
  

KOJAK

http://icl.cs.utk.edu/kojak/index.html

Pros:

• Event-trace generation

• Automatic diagnose of inefficient runtime behavior
  

Cons:

• "It does not work very well with long running programs" -Kojak's authors

PGI-CDK

http://www.pgroup.com/products/cdkindex.htm

Pros:

• MPI+OpenMP Profiling

• Includes the PGI Fortran Compiler and other cluster tools
  
• Powerful?
• Good documentation and support
• Measure scalability between multiple execution runs with varying number of processes/threads [4]
• Supports both sample-based and intsrumentation based profiling
  

Cons:

• Commercial, price on chart
  

• Annual Service Subscription

Opt

http://www.allinea.com/index.php?page=74

Pros:

• MPI+OpenMP Profiling

• Cross-platform

• OPT can compare multiple runs to assess code scalability [3]

• No need to instrument your code

• View statistical overviews and detailed views of user-defined metrics: for multiple jobs, across chosen processors and against time [3]

• Configure function measurement and granularity at run time [3]

• Grid-enabled

Cons:

• Commercial Software

• Price currently unknown
  

MPE/Jumpshot

http://www-unix.mcs.anl.gov/perfvis/software/viewers/index.htm

Pros:

• MPI Logging/tracing

• Cross-Platform (just need java2 runtime)

• Distributed with MPICH

• Scales well

• Free

• Auto-instrumentation

Cons:

• The auto-instrumentation could use some work
  

• Only event-based metrics

• Doesn't profile OpenMP
• Mostly only deals with MPI
  

MPIP

http://mpip.sourceforge.net/

Pros:

• Good high level statistics about MPI calls
• Scales Well
• Free!
• Might be useful in the beginning
  

Cons:

• Only does MPI, no OpenMP
• No call graphs
• Probably not detailed enough once we really get into profiling
  

http://www.paradyn.org/

Pros:

• Dynamic binary instrumentation - no need to modify code
• Free
• Scales extremely well
• MPI Profiling
• Can add user defined metrics
• Good documentation
  

Cons:

• No OpenMP Profiling
• Buggy
• Steep learning curve
  

http://www.renci.org/software/svpablo/

Pros:

• Supports MPI, OpenMP
• GUI based interactive instrumentation
• Really Good documentation
• Free
• Scalability analysis
  

Cons:

• Buggy
• Decent learning curve
• No communication profiling
  

VTune

http://www.intel.com/cd/software/products/asmo-na/eng/vtune/vlin/239145.htm

Pros:

• Powerful?
• Supports MPI, OpenMP
• Scales very well
• Modification of code not necessary
• Programming Language and Compiler Independent

Cons:
