Release 3.3 Information

Paradyn is a tool for measuring and analyzing the performance of sequential, parallel, and distributed programs. Paradyn can monitor large, long running programs and provides facilities for helping to automatically find performance problems in complex parallel programs. Paradyn operates on executable files by dynamically inserting and customizing measurement code while the program is running.

Release 3.0 Information

Dyninst is an Application Program Interface (API) that permits the insertion of code into a running program. The goal of this API is to provide a machine independent interface to permit the creation of tools and applications that use runtime code patching. This API is based on the idea of Dynamic Instrumentation.

Functional Improvements

ability to instrument more types of functions in applications on x86 and Sparc platforms
separate window to display application stderr/stdout output
ability to export data from visualizations
now handle MPI applications that create message tags at a rapid rate
now handle applications with multiple names for the same function

Technical Improvements

sampling of applications cputime can now use hardware counters on AIX
sampling of wall time has been made much more efficient for AIX
64 bit data path now from data collection to main Paradyn process
scalability improvements when aggregating sampling data
better handling of sample timestamps during data collection
increased optimization of instrumentation based on sharing of common subexpressions

Functional Improvements

ability to instrument more types of functions in applications on x86 and Sparc platforms
instrumentation can now be inserted at arbitrary points in code (all platforms)
findFunction call now finds uninstrumentable functions
new isInstrumentable method of BPatch_function, which indicates whether a function can be instrumented.
ability to save an instrumented application back to disk so Dyninst can be used as a static binary rewriting tool (implemented only on the Sparc/Solaris)
