PADE is designed to execute on workstations running the Unix
operating system and its variants. Most of its functionality consists of
executing other standalone programs. These programs therefore define the
basic system requirements, which can be summarized as follows:
- PADE needs to run on only one node of the virtual machine,
called the development host. Communication among nodes is
handled by a message-passing library (PVM), and the only requirement
upon the other nodes is that they support that library and pvmmake.
Operation of PADE takes place entirely on the development host.
The pvmmake utility, which performs all essential file transfers
and command executions, must be installed on all nodes of the VM,
however.
- The development host must run basic Unix commands (including in
particular man, col, and wc), and the X-windows
windowing system. In addition, it essential that the development
host run the following programs, which are freely available over
the Internet:
- PVM (version 3.0 or later)
- Tcl/Tk (version 7.3 of Tcl, version 3.6 of Tk, or later)
- Obtaining PADE's full functionality requires that the development
host run the following programs, also freely available over the
Internet
- XPVM
- Mosaic, or any other X-Windows-based WWW browser
Information on how to get these programs is contained in Section
2.4 below.
A key tenet of the PADE design concept is that it must enhance the utility
of the underlying message-passing library, and thus it must be accessible to
any user of that library. Thus, like all the programs itemized above, PADE
can be installed by any user; no system privileges are required. However,
the installer will need to know the locations of certain system resources,
as described in Section 2.5.
