Figure 4.17 gives a simple example of the encapsulation of
a non-standard call to a simulation tool.
By the deftool statement, residing in a configuration file
loaded on start-up of VISTA/SFC,
the process simulator TSUPREM4 is defined to be
called via the script local-ts4, which needs additional options.
The VLISP command vos::tool returns an
object job that represents the tool call.
The last line of the example shows the UNIX command line that
is generated by the tool call
.
Figure 4.18 gives an example of a tool that is only
authorized to run on certain hosts. In this case, only two hosts,
h50 and h51 are allowed for the simulator to run on.
On invocation time, the VISTA/SFC load balancing mechanism
[KPR
96] selects the best available host and starts the simulator.
