Getting Started

To start using Prism's TNF performance analysis, you can load your Sun MPI program into Prism and issue these three commands:

• Select Collection, from Prism's Performance analysis menu, or issue the tnfcollection on command from Prism's command line. For example:

(prism all) tnfcollection on

• Select the Run command from Prism's Execute menu or issue the run command from Prism's command line. For example:

(prism all) run

• Select Display TNF Data from Prism's Performance analysis menu, or issue the tnfview command from Prism's command line. For example:

(prism all) tnfview

The details that describe Prism's performance analysis, and how you can gain greater control of those details, are described in the rest of this chapter.
