# 3.1 Main Window

Figure 3.1: Main control window of Jumpshot-4.

The first window that pops up when invoking Jumpshot-4 is called the Main window, as shown in Figure 3.1. The buttons shown in the toolbar are shortcuts to the submenu items in the top menu bar. The function of each of these buttons is listed in Table 3.2. Two text fields display crucial information about the logfile being processed. The text field entitled LogName displays the pathname of the logfile being processed. The pulldown menu entitled ViewMap lists all the available ViewMaps in the SLOG-2 file. The CLOG3.1, older CLOG-23.2 and RLOG-converted3.3 SLOG-2 files contain one ViewMap, called the Identity Map. The recent CLOG-2 and IBM's UTE trace-converted SLOG-2 file contains multiple ViewMaps, e.g. a CLOG-2 logfile generated from a multi-threaded MPI program contains the Process-Thread and Communicator-Thread ViewMaps besides the Identity Map.
