The taskers.tcl File
The taskers.tcl file describes the taskers for a project.
The taskers.tcl file is a Tcl script based
on the procedure vtk_tasker_define. The
synopsis for this
procedure:
vtk_tasker_define hostname [options]The two following examples both declare three taskers on the
hosts apple orange and pear:
# Fragment of taskers.tcl file
vtk_tasker_define apple
vtk_tasker_define orange
vtk_tasker_define pear# Fragment of taskers.tcl file
foreach host {apple orange pear} {
vtk_tasker_define $host
}The following procedure supports many options to define the characteristics of the tasker. The options include "-resources <string>"
to set the resource list offered by a tasker and -CPUS n
to define the number of CPUs in a machine. In the following example, the
tasker on apple is set up to offer the resource
"big_memory":
# Fragment of tasker file
vtk_tasker_define apple -resources "@STD@ big_memory" -CPUS 2
vtk_tasker_define orange -resources "@STD@ big_memory" -CPUS 2
vtk_tasker_define pear -resources "@STD@ big_memory" -CPUS 4The default value for all options can be changed with the following procedure
vtk_tasker_set_defaults,
as shown below:
# Fragment of taskers.tcl file
vtk_tasker_set_default -resources "@STD@ big_memory" -CPUS 2
vtk_tasker_define apple
vtk_tasker_define orange
vtk_tasker_define -CPUS 4
