TPTP User Experiences Profiling

Note that when you edit a page on the wiki, there is a checkbox you can click to be notified of updates to the page. I'm not 100% sure if it works but if it does, it will be a good way to avoid having to cc a mailing list whenever you update the wiki...

This page discusses user types that we are hoping to solicit feedback regarding user experiences. In particular, we hope to get pointed feedback and make TPTP better for these classes of users.

J2SE

J2SE 5 and J2SE 6 are supported in TPTP by the new JVMTI interface while J2SE 1.4 and below are supported using the old JVMPI interface. The components of TPTP profiler that are evolving the most relate to the JVMTI profiling experience. If you don't know what version of Java you are using, please use java -version.

• Users of J2SE 5 and J2SE 6 JVMs
• Doesn't require third party's software

• Easy to deploy
• Isn't very specific application field. Purpose and simple use cases are understandable without special knowledge. Short time for familiarization
• Absence or minimum of native libraries
• Can be downloaded from CVS and built from scratch in Eclipse
