perl v5.38.2                                       2024-08-10                VM::EC2::REST::placement_group(3pm)

       Placement groups provide low latency and high-bandwidth connectivity between cluster instances within a
       single Availability Zone. Create a placement group and then launch cluster instances into it. Instances
       launched within a placement group participate in a full-bisection bandwidth cluster appropriate for HPC
       applications.

       Implemented:
        CreatePlacementGroup
        DeletePlacementGroup
        DescribePlacementGroups

   @groups=$ec2->describe_placement_groups(@group_names)@groups=$ec2->describe_placement_groups(\%filters)@groups=$ec2->describe_placement_groups(-group_name=>\@ids,-filter=>\%filters)
       This method will return information about cluster placement groups as a list of VM::EC2::PlacementGroup
       objects.

       Optional arguments:

        -group_name         -- Scalar or arrayref of placement group names.

        -filter             -- Tags and other filters to apply.

       The filters available are described fully at:
       http://docs.amazonwebservices.com/AWSEC2/latest/APIReference/ApiReference-query-DescribePlacementGroups.html

           group-name
           state
           strategy

   $success=$ec2->create_placement_group($group_name)$success=$ec2->create_placement_group(-group_name=>$name,-strategy=>$strategy)
       Creates a placement group that cluster instances are launched into.

       Required arguments:
        -group_name          -- The name of the placement group to create

       Optional:
        -strategy            -- As of 2012-12-23, the only available option is 'cluster'
                                so the parameter defaults to that.

       Returns true on success.

   $success=$ec2->delete_placement_group($group_name)$success=$ec2->delete_placement_group(-group_name=>$group_name)
       Deletes a placement group from the account.

       Required arguments:
        -group_name          -- The name of the placement group to delete

       Returns true on success.
