      org.griphyn.cPlanner.selector.site.Group

Group
public class Group extends Abstract (Code)
A site selector than ends up doing grouping jobs together on the basis of an identifier specifed in the dax for the jobs, and schedules them on to the same site. Currently, the identifier is key group in the vds profile namespace. All the jobs that do not have a group associated with them are put in one default group and end up being scheduled on the same pool. A limitation of this site selector is that it does not check whether all the jobs can be scheduled on a particular pool or not. It just checks whether the first job can be or not. The reason for that is after the grouping the the selector just hands the first job in each group to the other site selectors that work on jobs. Currently, it hands it to the Random Site Selector.

Constructor Detail
Group
public Group()(Code)
The default constructor.




Method Detail
description
public String description()(Code)
Returns the description of the site selector. description.



initialize
public void initialize(PegasusBag bag)(Code)
Initializes the site selector.
Parameters:
  bag - the bag of objects that is useful for initialization.



mapWorkflow
public void mapWorkflow(Graph workflow, List sites)(Code)
The call out to map a list of jobs on to the execution pools. A default implementation is provided that internally calls mapJob2ExecPool(SubInfo, String,String,String) to map each of the jobs sequentially to an execution site. The reason for this method is to support site selectors that make their decision on a group of jobs i.e use backtracking to reach a good decision. The implementation that calls out to an executable using Runtime does not implement this method, but relies on the default implementation defined here.
Parameters:
  workflow - the workflow that needs to be scheduled.
Parameters:
  sites - the list of String objects representing theexecution pools that can be used.
