my $sacctmgr = new Slurm::Sacctmgr;
my $list = Slurm::Sacctmgr::Association->sacctmgr_list($sacctmgr);
#List all associations known to sacctmgr
foreach $association (@$list)
{ #association is a Slurm::Sacctmgr::Association object
$uname = $association->user;

$partition = $association->partition;
$cpumins = $association->grpcpumins;
print "$uname $cluster $partition $cpumins\n";
}
...DESCRIPTION
Represents a Association entity in Slurm::Sacctmgr. Together with an instance of Slurm::Sacctmgr, this class allows one to issue commands to the Slurm sacctmgr command list or show entities of type "association".
The Slurm::Sacctmgr class provides a Perlish wrapper around the actual Slurm sacctmgr command, thus the methods provided by this class largely map quite straightforwardly onto sacctmgr commands. When using the sacctmgr_list method for this class, the results from the sacctmgr command is automatically parsed and presented as objects of this class.
Objects of this class contain the following data members:
- account: the account for the association
- cluster: the cluster for the association
- user: the user for the association
- partition: the partition for the association
- defaultqos: the default QoS for this association
- grpcpumins: the total number of CPU minutes usable by jobs with this association
- grpcpus: the maximum number of CPUs running jobs in this association can have allocated
- grpjobs: the maximum number of running jobs this association can have
- grpnodes: the maximum number of nodes jobs running in this association can have allocated
- grpsubmitjobs: the maximum number of jobs (pending or running) the association can have at a time
- grpwall: the maximum wall clock time jobs running in the association can have
- id: the id number for this association
- lft, rgt: index numbers, all children of this association will have an lft between this lft and rgt
- maxcpumins: the maximum number of CPU minutes each job in this association can use
- maxcpus: the maximum number of CPUs each job in this association can use
- maxjobs: the maximum number of jobs each user in this association can run at one time
- maxsubmitjobs: the maximum number of jobs (pending or running) each user in this association can have at a given time
- maxwall: the maximum wall clock time each job in this association can use
- parentid: the id number of the parent of this association
- parent: the name of the parent of this association
- qos: the QoSes that jobs in this association can use
and these are the fields that will be set by the sacctmgr_list and similar methods. When filtering results, you can use any fields recognized by the sacctmgr command.
Most functionality is provided via the base classes,
As a result, the whole Slurm::Sacctmgr::* family (for different entity types) all have a very similar association interface (basically the differences are what operations sacctmgr allows on different entity types, and how the results of list/show operations get parsed).
Sacctmgr does NOT allow the direct addition, deletion and/or modification of associations --- instead you should add, delete, or modify the user or account, etc. entities to which the associations attach.
As such, the only real method provided by this package is sacctmgr_list($sacctmgr, %where). This will return a list reference of all associations matching the "where" clause. The "where" clause is a list of zero or more key => value pairs specifying the conditions. Only exact matching is supported, and keys cannot be usefully repeated (the "where" clause is treated as a hash, so later keys simply overwrite earlier keys). You can use any parameter the Slurm sacctmgr command allows you to filter on. If no key => value pairs are given, all entities of this type are returned.
EXPORT
Nothing. Pure OO interface.
