The Run menu button is the second button from the left at the top of
the main PADE window. When this button is clicked with the left mouse button,
the Run pulldown menu appears. This menu is pictured in Fig. (5.2). The entries in this menu allow the user to perform
two major operations: (1) executing pvmmake and (2) executing the
parallel application currently under development. There are five entries in
the Run menu. These entries are
- pvmmmake config file - enables the user to select the
pvmmake configuration file to be used when pvmmake is launched.
When this menu-entry is selected, a dialog box appears. This dialog box is
divided into two parts. The top part consists of a text-entry box preceded
by the words Enter pvmmake config file:. The user is requested here to
enter the fully qualified path name of the pvmmake config file
needed. On the bottom of this dialog box are four buttons. These buttons
are the Clear, File Browser, Done, and Cancel
buttons. These buttons perform the following functions
- Clear - Erase any text in the text-entry box.
- File Browser - Invoke a file browser/selection window allowing
the user to select the needed pvmmake config file using the mouse.
- Done - With this button, the user indicates that the required
file has been entered. Note that, if the file name entered does not exist,
this information will appear stating this. To re-enter a file name, the user
must reselect the pvmmake config file menu entry in the Run menu.
- Cancel - Selecting this button causes the dialog box to disappear
with no pvmmake config file having been selected.
Note that if there is a file currently selected as the pvmmake config
file, its name appears in the pvmmake config file menu-entry.
- List pvmmake config file - Selection of this menu-entry causes
a window to appear in which the current pvmmake config file is displayed.
The user can scroll through this file to ensure that the correct pvmmake
commands will be executed. There are two buttons at the bottom of this
display window. They are
- Save - Selection of this button causes the file browser window
to appear; the user can enter a file name in which the contents of the
display window are saved.
- Done - Selection of this button causes the display window to
disappear.
Experience shows that this display window is quite useful in guarding against
incorrect pvmmake commands being executed. Users are encouraged to
always examine the pvmmake config file before launching pvmmake.
- Run pvmmake - This menu entry launches pvmmake. Any
output that pvmmake would normally write to stdout is collected
by PADE and displayed in a window identical to that used to display the
pvmmake config file.
- PVM application - This menu entry enables the user to indicate to
PADE the command used to launch the parallel application currently under
development. Its selection causes the file browser window to be invoked.
- Run - This menu entry enables the user to launch the application
being developed. The application to be launched must have been previously
selected using the PVM application menu-entry. Selection of this
entry opens a new xterm window in which the previously selected command
is executed. When the application has ended, the xterm window remains
on the screen for an hour unless closed by the user and then exits. Launching
the application in an xterm window enables the user to interactively
provide input to the application. If such interaction can be avoided, there
is another method by which the application can be launched which may be more
desirable. This method is described in Chapter 4.
