PerfExplorer uses TAUdb and PerfDMF databases so if you have not already you will need to install TAUdb, see Chapter 28, Introduction. After installing and configuring TAU the perfexplorer executable should be available in your [path to tau]/tau2/[arch]/bin directory. You will need to run perfexplorer_configure, installed at the same location as perfexplorer, to set up your database for use with perfexplorer and to download additional 3rd party jar files perfexplorer requires. When prompted by perfexplorer_configure give the name of your PerfDMF or TAUdb database and press Y to agree to download the jar files.
