=head1 NAME VM::EC2::REST::placement_group - Placement groups
=head1 SYNOPSIS
use VM::EC2 ':hpc'
=head1 METHODS
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
=head2 @groups = $ec2->describe_placement_groups(@group_names)
=head2 @groups = $ec2->describe_placement_groups(\%filters)
=head2 @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

=head2 $success = $ec2->create_placement_group($group_name)
=head2 $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.

=head2 $success = $ec2->delete_placement_group($group_name)
=head2 $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.
