PerfExplorer uses TAUdb and PerfDMF databases so if you have not already you will need to install TAUdb, see [taudb.intro] . 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.
